Claims
- 1. A one color copying machine capable of color annotation in a different color of the type having a transporting means for transporting a copy sheet along a transport path from an entrance location to an outlet location; a recording member; charging means for uniformly charging the recording member in preparation for imaging; means for exposing the recording member to produce a latent electrostatic copy image on the recording member; developing means for developing the image on the recording member; transfer means for transferring the developed image to a copy sheet to reproduce an original; and a fuser assembly for fusing developed images onto the copy sheet, said recording member, charging means, exposing means, developing means, transfer means and fuser assembly being located along said transport path, the machine further comprising:
- a memory capable of storing annotated image data;
- a thermal ink jet printing array, of a color, other than said one color copying machine, located along said transport path between said transfer means and said fuser assembly; and
- control means for controlling printing of annotated image data by said thermal ink jet printing array onto said copy sheet after transfer of a first unfused image portion to said copy sheet by said copying machine and before fusing by said fuser assembly.
- 2. A printing device comprising a black-only electrophotographic printing assembly and a thermal ink jet printing assembly capable of forming a composite image, comprising:
- first data supplying means for supplying a first set of data signals representing a first portion of an image to be reproduced, the first portion being scanned from an original document;
- second data supplying means separate from said first data supplying means for supplying a second set of data signals representing a second portion of an image to be reproduced:
- receiving means for receiving and storing said first set of data signals and said second set of data signals;
- a black-only electrophotographic printing assembly located along a copy sheet transport path;
- a fuser located downstream of said electrophotographic printing assembly along said sheet transport path; and
- a thermal ink jet printing assembly located between said electrophotographic printing assembly and said fuser along said sheet transport path, wherein said first set of data signals is used to form an unfused first image portion onto a copy sheet using said electrophotographic printing assembly and said second set of data signals is used to form a second image portion onto the copy sheet using said thermal ink jet printing assembly, said second image being formed onto the copy sheet prior to fusing of said first portion.
- 3. The apparatus of claim 2, wherein said second data supplying means includes at least one device from the group consisting of a personal computer, a word processor, a User Interface and a facsimile machine.
- 4. The apparatus of claim 2, further including an inverting means for inverting said second set of data signals prior to printing to provide an inverted black outline wherein a black outline of said second set of data signals is printed using said electrophotographic printing assembly and an inner fill area of said second set of data signals is printed using said thermal ink jet printing assembly.
- 5. A method of forming a composite color image, comprising the steps of:
- (a) receiving a first set of data signals representing a first portion of an image to be reproduced;
- (b) receiving a second set of data signals representing a second portion of an image to be reproduced;
- (c) inverting said second set of data signals to provide a negative image having a black outline and colored inner fill area;
- (d) printing the first portion of the image and said black outline of said inverted second set of data signals using electrophotographic printing assembly in a first resolution; and
- (e) printing the colored inner fill area of said second portion of the image on top of the first portion using a thermal ink jet printing assembly in a second, lower resolution.
- 6. A method of forming a composite color image using a xerographic device having an electrophotographic printing assembly with a single, black-only developer unit, comprising the steps of:
- (a) receiving a first set of data signals representing at least a portion of an original document;
- (b) receiving a second set of data signals representing a color portion of said composite color image;
- (c) transporting a copy sheet along a transport path within the xerographic device past a black-only electrophotographic printing assembly;
- (d) utilizing said first set of data signals to print an unfused first portion of said composite image on said copy sheet using said black-only electrophotographic printing assembly;
- (e) transporting said copy sheet to a thermal ink jet printing assembly located along said transport path; and
- (f) utilizing said second set of data signals to print a second portion of said composite image on said copy sheet in a color other than black using said thermal ink jet printing assembly, said step being performed prior to fusing of said unfused first portion.
- 7. The method of claim 6, wherein said step of printing with said xerographic printing assembly prints at a higher resolution than said step of printing with said thermal ink jet printing assembly.
- 8. The method of claim 7, wherein one set of said data signals are inverted prior to printing to provide a negative image.
- 9. The method of claim 1, wherein said step of printing with said thermal ink jet printing assembly prints at a resolution substantially the same as said electrophotographic printing assembly.
- 10. The method of claim 6, wherein a drying step is performed after step (e) to dry both the first portion and the second portion simultaneously.
- 11. The method of claim 10, wherein said drying step is performed by a fuser assembly.
