BACKGROUND
The present disclosure relates generally to information handling systems, and more particularly to producing an image with a printing device which is coupled to the information handling system.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Many information handling systems typically include a printing device coupled to the information handling system for producing images. Printing devices such as, for example, laser printers, exhibit a noticeable failure rate due to a large number of moving and wearing mechanical parts. For example, conventional laser printers may use a laser beam directed at a high speed rotating polygon mirror which reflects the laser beam towards a photoconductor to remove charge from the photoconductor as part of producing an image. The beam from the laser strikes one of the mirror surfaces on the polygon mirror and is reflected across a range of angles as the polygon mirror rotates in front of the beam. When the mirror facet turns out of the beam path of the laser, a new mirror facet is rotated into the laser beam path, and that mirror facet moves across the beam path to repeat the sweep of beam angles that were made by the previous facet. This rotating polygon mirror is a mechanical part which is prone to failures, while the drive motor and circuitry for the polygon mirror create undesirable heat. To mitigate this and other reliability issues the industry uses preventive maintenance, where either a technician or the customer must replace certain wearing parts on a predetermined basis.
Furthermore, due to the fact that cost increases as the speed of the paper path increases in the laser printer, low cost laser printers tend to be slow.
Accordingly, it would be desirable to provide for producing an image absent the disadvantages found in the prior methods discussed above.

Referring now to FIG. 2, a conventional printing device 200 is illustrated. The printing device 200 includes a photoconductor drum 202 having a charging surface 202a and a rotation axis 202b. In an embodiment, the photoconductor drum 202 may be a variety of photoconductors known in the art such as, for example, an Organic Photo Conductor (OPC), a photoconductor belt, a photoconductor plate, combinations thereof, or a variety of other photoconductors known in the art. A printing medium path 204 is located adjacent the photoconductor drum 202. An input engine 206 is located adjacent the printing medium path 204. A first charging member 208 is located adjacent the printing medium path 204 and opposite the photoconductor drum 202. A fusing device 210 is located adjacent the printing medium path 204 and includes a fuser 210a and a fusing engine 210b located on opposite sides of the printing medium path 204. An output engine 212 is located adjacent the printing medium path 204. A cleaning member 214 is located in a housing 214a and adjacent the photoconductor drum 202 such that a plurality of cleaning fins 214b on the cleaning member 214 may engage the charging surface 202a of the photoconductor drum 202. A second charging member 216 is located adjacent the photoconductor drum 202. A toner application device 218 is located adjacent the photoconductor drum 202 and includes a plurality of toner application members 218a and 218b located in a housing 218c.
Referring now to FIG. 3, an image producing apparatus 300 is illustrated. The image producing apparatus 300 includes a substrate 302 having a top surface 302a. A control layer 304 includes a top surface 304a, is coupled to the top surface 302a of the substrate 302, and includes a variety of conventional control circuitry known in the art. A photonic energy device 306 is coupled to the top surface 304a of the control layer 304 and may be controlled by the control layer 304. In an embodiment, the photonic energy device 306 may be, for example, a laser, a controlled pulse laser, a light emitting device (LED), or a variety of equivalent photonic energy devices known in the art. An optics device 308 is positioned adjacent the photonic energy device 306. In an embodiment, the optics device 308 includes a static optics device operable to focus a photonic energy beam from the photonic energy device 306. A reflecting member 310 is located proximate the photonic energy device 306 and the optics device 308 on the top surface 304a of the control layer 304 and, in an embodiment, is coupled to the top surface 304a of the control layer 304 by a support structure 312. In an embodiment, the support structure 312 and/or the reflecting member 310 are fabricated from a piezoelectric material known in the art such as, for example, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, barium sodium niobate, barium titanate (BaTiO3), Lithium Niobate, Lithium tantalate, Lead Zirconate Titanate (PZT-2, PZT-4, PZT-4D, PZT-5A, PZT-5H, PZT-5J, PZT-7A, PZT-8), Bismuth Germanate, Quartz, Rochelle Salt, Polyvinylidene Flouride, Cadmium Sulfide, Gallium Arsenide, Tellurium Dioxide, Zinc Oxide, and/or Zinc Sulfide, each which may be doped onto or built up as part of the image producing apparatus 300. In an embodiment, the image producing apparatus 300 may include a layer of transparent material such as, for example, transparent silicon, pyrex, glass, and/or a variety of other transparent materials known in the art, in order to protect the components of image producing apparatus 300.
Referring now to FIGS. 2, 3, 4a, 4b, and 4c, a method 400 for producing an image is illustrated. In the illustrations describing the method 400, for clarity, some components have been illustrated larger than normal such that the illustration is not to scale. The method 400 begins at step 402 where printing device 200 including the photoconductor drum 202 is provided. In an exemplary embodiment, the printing device 200 may be coupled to the information handling system 100, described above with respect to FIG. 1, and controlled by the microprocessor 102, described above with respect to FIG. 1. The image producing apparatus 300 including the photonic energy device 306 and the reflecting member 310 is positioned adjacent the photoconductor drum 202 using methods known in the art, as illustrated in FIGS. 4b and 4c. The method 400 then proceeds to step 404 where the photoconductor drum 202 is charged. The photoconductor drum 202 rotates about the rotation axis 202b in a direction A, and during the rotation of the photoconductor drum 202, the cleaning fins 214b on the cleaning member 214 engage the surface 202 of the photoconductor drum 202 to clean off a waste toner 402a that may exist due to prior use of the photoconductor drum 202. Further rotation of the photoconductor drum 202 allows the cleaned surface 202a of the photoconductor drum 202 to be positioned adjacent the second charging member 216, which charges the surface 202a of the photoconductor drum 202 using methods known in the art.
Referring now to FIGS. 4a, 4b, 4d, 4e, 4f, 4g, 4h, and 4i, the method 400 proceeds to step 406 where portions of the photoconductor drum 202 are discharged. The control layer 304 supplies an electrical voltage to the support structure 312 using methods known in the art which, due to the material the support structure 312 is fabricated from, results in the deformation of the support structure 312.
In an embodiment, a relatively low electrical voltage is supplied from the control layer 304 to the support structure 312, resulting in the deformation of the support structure 312 illustrated in FIGS. 4d and 4e. In an embodiment, the electrical voltage may be a sinusoidal voltage in order to create a sinusoidal bending pattern in the support structure 312. The deformation of the support structure 312 positions the reflecting member 310 in an orientation B. The photonic energy device 306 is then activated, which sends a photonic energy beam 406a through the optics device 308 and towards the reflecting member 310. The photonic energy beam 406a is then reflected off the reflecting member 310 and onto an edge 406aa of the surface 202a of the photoconductor drum 202. The contact of the photonic energy beam 406a and the surface 202a of the photoconductor drum 202 discharges the edge 406aa of the surface 202a which had been charged in step 404 of the method 400.
In an embodiment, a relatively average electrical voltage is supplied from the control layer 304 to the support structure 312, resulting in the deformation of the support structure 312 illustrated in FIGS. 4f and 4g. In an embodiment, the electrical voltage may be a sinusoidal voltage in order to create a sinusoidal bending pattern in the support structure 312. The deformation of the support structure 312 positions the reflecting member 310 in an orientation C. The photonic energy device 306 is then activated, which sends a photonic energy beam 406b through the optics device 308 and towards the reflecting member 310. The photonic energy beam 406b is then reflected off the reflecting member 310 and onto a portion 406ba of the surface 202a of the photoconductor drum 202. The contact of the photonic energy beam 406b and the surface 202a of the photoconductor drum 202 discharges the portion 406ba of the surface 202a which had been charged in step 404 of the method 400.
In an embodiment, a relatively large electrical voltage is supplied from the control layer 304 to the support structure 312, resulting in the deformation of the support structure 312 illustrated in FIGS. 4h and 4i. In an embodiment, the electrical voltage may be a sinusoidal voltage in order to create a sinusoidal bending pattern in the support structure 312. The deformation of the support structure 312 positions the reflecting member 310 in an orientation D. The photonic energy device 306 is then activated, which sends a photonic energy beam 406c through the optics device 308 and towards the reflecting member 310. The photonic energy beam 406c is then reflected off the reflecting member 310 and onto an edge 406ca of the surface 202a of the photoconductor drum 202. The contact of the photonic energy beam 406c and the surface 202a of the photoconductor drum 202 discharges the edge 406ca of the surface 202a which had been charged in step 404 of the method 400.
In an embodiment, different electrical voltages may be supplied by the control layer 304 in order to deform the support structure 312 such that different photonic energy beams such as, for example, the photonic energy beams 406a, 406b, and 406c linearly scan across the surface 202a of the photoconductor drum 202 as the photoconductor drum 202 rotates in the direction A in order to discharge portions on the surface 202a of the photoconductor drum 202 corresponding to an image to be produced. In an embodiment, rather than being a relatively rigid reflecting member 310 coupled to a deformable support structure 312, as illustrated in FIGS. 4d, 4e, 4f, 4g, 4h, and 4i, a deformable reflecting member may replace the reflecting member 310 and support structure 312 combination such that the deformable reflecting member deforms upon application of an electrical voltage, which allows reflection of the photonic energy beam in substantially the same manner as described above for FIGS. 4d, 4e, 4f, 4g, 4h, and 4i.
Referring now to FIGS. 4a and 4b, the method 400 proceeds to step 408 where toner is applied to the charged areas of the photoconductor drum 202. The photoconductor drum 202 continues to rotate in the direction A, which results in the partially charged surface 202a of the photoconductor drum 202 being positioned adjacent the toner application device 218. The toner application members 218a and 218b then supply a toner 408a adjacent the photoconductor drum 202, and as a result of the remaining charge on portions of the surface 202a of the photoconductor drum 202, the toner 408a is drawn to and held on the portions of the surface 202a which have not been discharged by the image producing apparatus 300 in step 406 of the method 400.
The method 400 then proceeds to step 410 where the toner 408a is transferred to a printing medium. A printing medium 410a such as, for example, paper, is supplied. The printing medium 410a is engaged by the input engine 206 and moved along the paper path 204 in a direction E such that it is positioned adjacent the first charging member 208. The first charging member 208 charges the printing medium 410a such that the charge level of the printing medium 410a is greater than the charge level given to the charging surface 202a of the photoconductor drum 202 by the second charging member 216 in step 404 of the method 400. As the photoconductor drum 202 continues to rotate in the direction A and the printing medium 410a continues to move in the direction E, the portions of the charging surface 202a of the photoconductor drum 202 including the toner 408a are positioned adjacent the charged printing medium 410a. Because the printing medium 410a is charged at a higher level than the surface 202a of the photoconductor drum 202, the toner is drawn to and held by the printing medium 410a.
The method 400 then proceeds to step 412 where an image is produced on the printing medium 410a. The printing medium 410a continues to move along the paper path 204 in the direction E until the printing medium 410a engages the fuser engine 210b and is adjacent the fuser 210a. The fuser 210a heats the toner 408a to its melting point and the fuser engine 210b presses the toner 408a into the printing medium 410a, providing an image on the printing medium 410a. The printing medium 410a then engages the output engine 212, which moves the printing medium 410a out of the paper path 204. Thus, an image producing apparatus 300 is provided which is relatively cheap to produce and maintain compared to a conventional image producing apparatus, exhibits a lower failure rate than a conventional image producing apparatus, and provides increased scalability and speed compared to a conventional image producing apparatus.
Referring now to FIG. 5, in an alternative embodiment, an image producing apparatus 500 is illustrated. The image producing apparatus 500 is substantially similar in design and operation to the image producing apparatus 300 described above with respect to FIGS. 1, 2, 3, 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, and 4i, with the provision of a plurality photonic energy devices 306, a plurality of optics devices 308, and a plurality of reflecting members 310 and support structures 312, coupled to the top surface 304a of the control layer 302 in place of the single photonic energy device 306, optics device 308, reflecting member 310 and support structure 312 of image producing apparatus 300. In an embodiment, the plurality of photonic energy devices 306 may be, for example, a laser, a controlled pulse laser, a light emitting device (LED), or a variety of equivalent photonic energy devices known in the art. In an embodiment, the support structure 312 and/or the reflecting member 310 are fabricated from a piezoelectric material known in the art such as, for example, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, barium sodium niobate, barium titanate (BaTiO3), Lithium Niobate, Lithium tantalate, Lead Zirconate Titanate (PZT-2, PZT-4, PZT-4D, PZT-5A, PZT-5H, PZT-5J, PZT-7A, PZT-8), Bismuth Germanate, Quartz, Rochelle Salt, Polyvinylidene Flouride, Cadmium Sulfide, Gallium Arsenide, Tellurium Dioxide, Zinc Oxide, and/or Zinc Sulfide, each which may be doped onto or built up as part of the image producing apparatus 500. In an embodiment, the image producing apparatus 500 may include a layer of transparent material such as, for example, transparent silicon, pyrex, glass, and/or a variety of other transparent materials known in the art, in order to protect the components of image producing apparatus 500.
Referring now to FIGS. 4a, 6a, and 6b, the image producing apparatus 500 may be operated in substantially the same manner as the image producing apparatus 300 using method 400, with the provision of a modified step 406, where the surface 202a of the photoconductor drum 202 is discharged. In the illustrations 6a and 6b, for clarity, some components have been illustrated larger than normal such that the illustration is not to scale. At step 406, the control layer 304 may apply varying electrical voltages to the support structures 312 in order to deform the support structures 312 and position the reflecting members 310 in different orientations such as, for example, the orientations B, C, and D, illustrated in FIGS. 4d, 4f, and 4h. In an embodiment, the electrical voltage may be a sinusoidal voltage in order to create a sinusoidal bending patterns in the support structures 312. The photonic energy devices 306 are then activated, which sends a plurality of photonic energy beams through the optics devices 308 and towards the reflecting members 310. The photonic energy beams are then reflected off the reflecting members 310 and onto the surface 202a of the photoconductor drum 202, each reflecting member 310 having a possible beam path 600 which provides a linear scan across the surface 202a of the photoconductor drum 202. The contact of the photonic energy beams and the surface 202a of the photoconductor drum 202 discharges the surface 202a which had been charged in step 404 of the method 400. In an embodiment, the possible beam paths 600 overlap such that any one beam path 600 is redundant, as illustrated in FIG. 6b, and failure of any one reflecting member 310 or photonic energy devices 306 may be compensated for by adjacent reflecting members 310 and photonic energy devices 306. In an embodiment, an image producing apparatus may include a plurality of the image producing apparatus 500 described above in order to provide a two dimensional multilinear scanning array. Thus, an image producing apparatus 500 is provided which is relatively cheap to produce and maintain compared to a conventional image producing apparatus, exhibits a lower failure rate than a conventional image producing apparatus, and provides increases scalability and speed compared to a conventional image producing apparatus.
Referring now to FIG. 7, in an embodiment, a printing device 700 is substantially similar in design and operation to the printing device 200, described above with reference to FIG. 2, with the provision of a photoconductor belt 702 replacing the photoconductor drum 202. The photoconductor belt 702 includes a charging surface 702a which is operable to move in a direction F, as illustrated in FIG. 7.
Referring now to FIG. 8, in an embodiment, an image producing apparatus 800 is substantially similar in design and operation to the image producing apparatus 300 described above with respect to FIG. 3, with the provision of a reflecting member 802 replacing the reflecting member 310 and the support structure 312. The reflecting member 802 includes a first deformable member 802a which is coupled to the top surface 304a of the control layer 304. A second reflective deformable member 802b is coupled to the first deformable member 802a. In an embodiment, the first deformable member 802a and the second reflective deformable member 802b are operable to deform in different orientations upon the application of an electrical voltage. In an embodiment, the first deformable member 802a and the second reflective deformable member 802b are fabricated from different piezoelectric materials. In an embodiment, the first deformable member 802a and the second reflective deformable member 802b may be fabricated from a piezoelectric material known in the art such as, for example, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, barium sodium niobate, barium titanate (BaTiO3), Lithium Niobate, Lithium tantalate, Lead Zirconate Titanate (PZT-2, PZT-4, PZT-4D, PZT-5A, PZT-5H, PZT-5J, PZT-7A, PZT-8), Bismuth Germanate, Quartz, Rochelle Salt, Polyvinylidene Flouride, Cadmium Sulfide, Gallium Arsenide, Tellurium Dioxide, Zinc Oxide, and/or Zinc Sulfide, each which may be doped onto or built up as part of the image producing apparatus 800. In an embodiment, the image producing apparatus 800 may include a layer of transparent material such as, for example, transparent silicon, pyrex, glass, and/or a variety of other transparent materials known in the art, in order to protect the components of image producing apparatus 800.
Referring now to FIGS. 7, 9a, 9b, 9c, 9d, and 9e, the image producing apparatus 800 may be positioned adjacent the printing device 700 and operated in substantially the same manner as the image producing apparatus 300 and the printing device 200 according to the method 400, with the provision of a modified step 406. In the illustrations 9a and 9d, for clarity, some components have been illustrated larger than normal such that the illustration is not to scale. At step 406, the control layer 304 applies an electrical voltage to the reflecting member 802. Due to the reflecting member 802 including the first deformable member 802a and the second reflective deformable member 802b which are operable to deform in different orientations, the application of the electrical voltage causes the reflecting member 802 to deform into an orientation G, as illustrated in FIG. 9b. In an embodiment, the electrical voltage may be a sinusoidal voltage in order to create a sinusoidal bending pattern in the first deformable member 802a and the second deformable member 802b. The photonic energy device 306 is then activated, which sends a photonic energy beam through the optics device 308 and towards the reflecting member 802. The photonic energy beam is then reflected off the second reflective deformable member 802b on reflecting member 802 and towards the surface 702a of the photoconductor belt 702. Application of different electrical voltages from the control layer 304 to the reflecting member 802 result in different deformation orientations of the reflecting member 802, which allow the photonic energy beam from the photonic energy device 306 to be reflected in variety of directions H such that the photonic energy beam may contact a portion I of the surface 702a on the photoconductor belt 702, as illustrated in FIGS. 9c, 9d, and 9e. The contact of the photonic energy beam and the surface 702a of the photoconductor drum 702 discharges the surface 702a which had been charged in step 404 of the method 400. Thus, an image producing apparatus 800 is provided which is relatively cheap to produce and maintain compared to a conventional image producing apparatus, exhibits a lower failure rate than a conventional image producing apparatus, and provides increased scalability and speed compared to a conventional image producing apparatus.
Referring now to FIG. 10, in an embodiment, an image producing apparatus 1000 is substantially similar in design and operation to the image producing apparatus 300 described above with respect to FIG. 3, with the provision of a reflecting member 1002 replacing the reflecting member 310 and the support structure 312. The reflecting member 1002 is coupled to the control layer 304 and defines a channel 1002a extending into the reflecting member 1002. In an embodiment, the reflecting member 1002 may be fabricated from a piezoelectric material known in the art such as, for example, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, barium sodium niobate, barium titanate (BaTiO3), Lithium Niobate, Lithium tantalate, Lead Zirconate Titanate (PZT-2, PZT-4, PZT-4D, PZT-5A, PZT-5H, PZT-5J, PZT-7A, PZT-8), Bismuth Germanate, Quartz, Rochelle Salt, Polyvinylidene Flouride, Cadmium Sulfide, Gallium Arsenide, Tellurium Dioxide, Zinc Oxide, and/or Zinc Sulfide, each which may be doped onto or built up as part of the image producing apparatus 1000. In an embodiment, the photonic energy device 306 and the optics device 308 may be mounted offset from the position illustrated in FIG. 10. In an embodiment, the image producing apparatus 1000 may include a layer of transparent material such as, for example, transparent silicon, pyrex, glass, and/or a variety of other transparent materials known in the art, in order to protect the components of image producing apparatus 1000.
Referring now to FIGS. 7, 11a, 11b, 11c, 11d, and 11e, the image producing apparatus 1000 maybe be positioned adjacent the printing device 700 and operated in substantially the same manner as the image producing apparatus 300 and the printing device 200 according to the method 400, with the provision of a modified step 406. In the illustrations 11a and 11d, for clarity, some components have been illustrated larger than normal such that the illustration is not to scale. At step 406, the control layer 304 applies an electrical voltage to the reflecting member 1002. Due to the channel 1002a defined by reflecting member 1002, the application of the electrical voltage causes the reflecting member 1002 to deform into an orientation J, as illustrated in FIG. 11b. In an embodiment, the electrical voltage may be a sinusoidal voltage in order to create a sinusoidal bending pattern in reflecting member 1002. The photonic energy device 306 is then activated, which sends a photonic energy beam through the optics device 308 and towards the reflecting member 1002. The photonic energy beam is then reflected off the reflecting member 1002 and towards the surface 702a of the photoconductor belt 702. Application of different electrical voltages from the control layer 304 to the reflecting member 1002 result in different deformation orientations of the reflecting member 1002, which allow the photonic energy beam from the photonic energy device 306 to be reflected in variety of directions K such that the photonic energy beam may contact a portion L of the surface 702a on the photoconductor belt 702, as illustrated in FIGS. 11c, 11d, and 11e. In an embodiment, the photonic energy device 306 and the optics device 308 may be mounted offset from the position illustrated in FIG. 10 such that the photonic energy device 306 may direct a photonic energy beam towards the reflecting member 1002 at an angle relative to the photonic energy beam illustrated in FIG. 11c in order to take advantage of different orientations of the reflecting member 1002 upon the application of an electrical voltage. The contact of the photonic energy beam and the surface 702a of the photoconductor drum 702 discharges the surface 702a which had been charged in step 404 of the method 400. Thus, an image producing apparatus 1000 is provided which is relatively cheap to produce and maintain compared to a conventional image producing apparatus, exhibits a lower failure rate than a conventional image producing apparatus, and provides increased scalability and speed compared to a conventional image producing apparatus.
Referring now to FIG. 12, in an embodiment, an image producing apparatus 1200 is substantially similar in design and operation to the image producing apparatus 300 described above with respect to FIG. 3, with the provision of a reflecting member 1202 replacing the reflecting member 310 and the support structure 312. The reflecting member 1202 is coupled to the control layer 304 and includes a first deformable member 1204 having a first axis 1204a. A support 1206 extends from the first deformable member 1204 and is operably coupled to the control layer 304. A second deformable member 1208 is coupled to the support 1206 and includes a second axis 1208a which is substantially perpendicular to the first axis 1208a. A reflecting device 1210 is coupled to the second deformable member 1208. In an embodiment, the first deformable member 1204 and the second deformable member 1208 may be fabricated from a piezoelectric material known in the art such as, for example, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, barium sodium niobate, barium titanate (BaTiO3), Lithium Niobate, Lithium tantalate, Lead Zirconate Titanate (PZT-2, PZT-4, PZT-4D, PZT-5A, PZT-5H, PZT-5J, PZT-7A, PZT-8), Bismuth Germanate, Quartz, Rochelle Salt, Polyvinylidene Flouride, Cadmium Sulfide, Gallium Arsenide, Tellurium Dioxide, Zinc Oxide, and/or Zinc Sulfide, each which may be doped onto or built up as part of the image producing apparatus 1200. In an embodiment, the image producing apparatus 1200 may include a layer of transparent material such as, for example, transparent silicon, pyrex, glass, and/or a variety of other transparent materials known in the art, in order to protect the components of image producing apparatus 1200.
Referring now to FIG. 13, the image producing apparatus 1200 maybe be positioned adjacent the printing device 700 in substantially the same manner as the image producing apparatus 800 and 1000, described above with reference to FIGS. 9a and 11a, and operated in substantially the same manner as the image producing apparatus 300 and the printing device 200 according to the method 400, with the provision of a modified step 406. At step 406, the control layer 304 may apply an electrical voltage to the first deformable member 1204 and the second deformable member 1208. The application of the electrical voltage to the first deformable member 1204 causes the first deformable member 1204 to deform such that the support 1206, the second deformable member 1208, and the reflecting device 1210 rotate about the first axis 1204a in a direction M. The application of the electrical voltage to the second deformable member 1208 causes the reflecting device 1210 to rotate about the second axis 1208a in a direction N. In an embodiment, the electrical voltage may be a sinusoidal voltage in order to create a sinusoidal bending pattern in the first deformable member 1204 and the second deformable member 1208. The photonic energy device 306 is then activated, which sends a photonic energy beam through the optics device 308 and towards the reflecting device 1210. The photonic energy beam is then reflected off the reflecting device 1210 and towards the surface 702a of the photoconductor belt 702. Application of different electrical voltages from the control layer 304 to the first deformable member 1204 and the second deformable member 1208 result in different deformation orientations of the reflecting member reflecting device 1210, which allow the photonic energy beam from the photonic energy device 306 to be reflected in variety of directions O such that the photonic energy beam may contact a portion L of the surface 702a on the photoconductor belt 702, as illustrated in FIG. 11e. The contact of the photonic energy beam and the surface 702a of the photoconductor drum 702 discharges the surface 702a which had been charged in step 404 of the method 400. Thus, an image producing apparatus 1200 is provided which is relatively cheap to produce and maintain compared to a conventional image producing apparatus, exhibits a lower failure rate than a conventional image producing apparatus, and provides increased scalability and speed compared to a conventional image producing apparatus.
Referring now to FIG. 14, in an embodiment, an image producing apparatus 1400 is substantially similar in structure and operation to the image producing apparatus 300 described above with respect to FIG. 3, with the removal of the reflecting member 310 and the support structure 312 and the provision of a plurality of walls 1402a and 1402b extending from the top surface 304a of the control layer 304, a first reflecting member 1404 including a first deformable member 1404a having a deformation axis 1404aa and a first reflecting device 1404b coupled to the top surface of the control layer 304, a support beam 1406 extending from the wall 1402b, and a second reflecting member 1408 including a second deformable member 1408a and a second reflecting device 1408b coupled to the support beam 1406. The second deformable member 1408 is coupled to the control layer 304 through the wall 1402b and the support beam 1406. In an embodiment, the first deformable member 1404a and the second deformable member 1404b may be fabricated from a piezoelectric material known in the art such as, for example, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, barium sodium niobate, barium titanate (BaTiO3), Lithium Niobate, Lithium tantalate, Lead Zirconate Titanate (PZT-2, PZT-4, PZT-4D, PZT-5A, PZT-5H, PZT-5J, PZT-7A, PZT-8), Bismuth Germanate, Quartz, Rochelle Salt, Polyvinylidene Flouride, Cadmium Sulfide, Gallium Arsenide, Tellurium Dioxide, Zinc Oxide, and/or Zinc Sulfide, each which may be doped onto or built up as part of the image producing apparatus 1400. In an embodiment, the image producing apparatus 1400 may include a layer of transparent material such as, for example, transparent silicon, pyrex, glass, and/or a variety of other transparent materials known in the art, in order to protect the components of image producing apparatus 1400.
Referring now to FIG. 15, the image producing apparatus 1400 may be positioned adjacent the printing device 700 in substantially the same manner as the image producing apparatus 800 and 1000, described above with reference to FIGS. 9a and 11a, and operated in substantially the same manner as the image producing apparatus 300 and the printing device 200 according to the method 400, with the provision of a modified step 406. At step 406, the control layer 304 may apply an electrical voltage to the first deformable member 1404a and/or the second deformable member 1408a. The application of the electrical voltage to the first deformable member 1404a causes the first deformable member 1404a to deform about the axis 1404aa. The application of the electrical voltage to the second deformable member 1408a causes the second deformable member 1408a to deform as illustrated in FIG. 15. In an embodiment, the electrical voltage may be a sinusoidal voltage in order to create a sinusoidal bending pattern in the first deformable member 1404a and the second deformable member 1408a. The photonic energy device 306 is then activated, which sends a photonic energy beam through the optics device 308 and towards the first reflecting device 1408b. The photonic energy beam is then reflected off the first reflecting device 1408b and towards the second reflecting device 1404b. The photonic energy beam is then reflected off the second reflecting device 1404b and towards the surface 702a of the photoconductor belt 702. Application of different electrical voltages from the control layer 304 to the first deformable member 1404a and the second deformable member 1408a result in different deformation orientations of the first reflecting member 1404 and the second reflecting member 1408, which allow the photonic energy beam from the photonic energy device 306 to be reflected in variety of directions such that the photonic energy beam may contact a substantially two dimensional area of the surface 702a on the photoconductor belt 702 similar to the portion L, as illustrated in FIG. 11e. The contact of the photonic energy beam and the surface 702a of the photoconductor drum 702 discharges the surface 702a which had been charged in step 404 of the method 400. Thus, an image producing apparatus 1400 is provided which is relatively cheap to produce and maintain compared to a conventional image producing apparatus, exhibits a lower failure rate than a conventional image producing apparatus, and provides increased scalability and speed compared to a conventional image producing apparatus.
