This application relates to and claims priority from Japanese Patent Application No. 2013-204469, filed in the Japan Patent Office on Sep. 30, 2013, and Japanese Priority Patent Application No. 2014-134623 based on Japanese Patent Application No. 2013-204469, filed in the Japan Patent Office on Jun. 30, 2014, the entire disclosures of which are incorporated herein by reference.
Unless otherwise indicated herein, the description in this field section or the background section is not prior art to the claims in this application and is not admitted to be prior art by inclusion in this section. The present disclosure relates to an image forming apparatus that can print on a sheet of paper including an index label (hereinafter referred to as “index sheet”), an image forming system, and a non-transitory computer-readable recording medium.
A typical image forming apparatus such as a printer and a multifunction peripheral (MFP) is configured to automatically print, when a paper jam is removed, an image that has failed to be printed on a subsequently-fed sheet of paper (automatic jam recovery function). Therefore, when a paper jam occurs during printing of a plurality of index sheets having index labels in different positions and then an index sheet that has caused the paper jam is removed, an image to be printed on the index sheet that has caused the paper jam is automatically printed on a subsequently-fed index sheet. However, the position of the index label on the subsequently-fed index sheet is different from the position of the index label on the index sheet that has caused the paper jam. In addition, when an image is printed also on the index label, the image is printed only on a fixed size part of the index sheet without being printed on the index label, which makes printing wasteful.
Therefore, for example, there is known an image forming apparatus in which, when a specific sheet of paper such as an index sheet exists inside the image forming apparatus at the occurrence of a conveying failure, an alternative sheet of paper different from the specific sheet of paper is fed at a timing to feed the specific sheet of paper in a later jam recovery process. Further, a message image indicating that a sheet of paper different from a proper sheet of paper has been fed due to the occurrence of the conveying failure is recorded on the alternative paper sheet and delivered, which allows a user to recognize necessity of recovery work.
In the known image forming apparatus, the user is allowed to recognize the necessity of recovery work, but in order to perform the printing for the index sheet that has caused the paper jam, it is necessary to set information on the index sheet, the index label, and the like again before the printing.
The present disclosure relates to an image forming apparatus that prevents wasteful printing due to deviation in sheet feeding when a paper jam occurs in printing on a plurality of index sheets having index labels in different positions and allow a user to select a pattern of handling the paper jam. The present disclosure also relates to an image forming system, and a non-transitory computer-readable recording medium including a printer driver.
In one embodiment, an image forming apparatus includes a printing processing unit, a paper jam detection unit, and an operation display unit. The printing processing unit performs printing on a plurality of index sheets having index labels in different positions. The paper jam detection unit detects a paper jam in the plurality of index sheets. The operation display unit displays, when the paper jam is detected, a paper jam handling pattern selection screen for selecting a paper jam handling pattern of the printing processing unit.
In another embodiment, an image forming system includes an image forming apparatus and a client apparatus which are connected to a network. The image forming apparatus includes a printing processing unit and a paper jam detection unit. The printing processing unit performs printing on a plurality of index sheets having index labels in different positions. The paper jam detection unit detects a paper jam in the plurality of index sheets. The client apparatus includes an operation display unit. The operation display unit displays, when the paper jam is detected, a paper jam handling pattern selection screen for selecting a paper jam handling pattern of the printing processing unit.
In yet another embodiment, a non-transitory computer-readable recording medium includes a printer driver. The printer driver causes a computer of a client apparatus to function as a print instruction unit and a printing processing unit. The print instruction unit instructs an image forming apparatus connected to the client apparatus via a network to perform printing. The image forming apparatus includes a printing processing unit that performs the printing on a plurality of index sheets having index labels in different positions, and a paper jam detection unit that detects a paper jam in the plurality of index sheets. The screen display unit displays a paper jam handling pattern selection screen for selecting a paper jam handling pattern of the printing processing unit, on an operation display unit of the client apparatus.

The operation unit 5 that performs settings of the image forming apparatus 1 and an operational instruction is located on a front side of the image forming apparatus 1. The operation unit 5 includes a liquid crystal display unit 51 and an operation button 52. A user operates the operation unit 5 to input an instruction, to thereby perform various settings of the image forming apparatus 1 and execute various functions such as image formation. The liquid crystal display unit 51 is configured to indicate the status of the image forming apparatus 1, display an image formation situation and a print unit count, and as a touch panel, perform functions such as double-sided printing and black-and-white inversion and various settings such as a magnification setting and a density setting. As the operation button 52, there are provided a start button that starts the image formation, a stop/clear button that cancels the image formation, a reset button used to initialize the various settings of the image forming apparatus 1 to default states, a numeric keypad, and the like.
The manuscript feeding unit 3 includes a manuscript placement unit 31, a manuscript delivery unit 32, and a manuscript conveying mechanism 33. The manuscripts MS set on the manuscript placement unit 31 are successively drawn out by the manuscript conveying mechanism 33 one sheet at a time to be fed to a position opposite the manuscript reading slit 23 and then delivered onto the manuscript delivery unit 32. Further, the manuscript feeding unit 3 and the manuscript reading unit 2 are joined to each other by a hinge mechanism on a rear side of the image forming apparatus 1, and the manuscript feeding unit 3 functions as a platen cover that opens/closes an upper surface of the platen glass plate 22. By opening the manuscript feeding unit 3 upward, the upper surface of the platen glass plate 22 is opened to allow the manuscript MS to be set on the platen glass plate 22.
When reading of the manuscript MS is instructed by the operation button 52 of the operation unit 5 in a state in which the manuscript MS is not set on the manuscript placement unit 31 or in an open state in which the manuscript feeding unit 3 (platen cover) is opened, the manuscript MS set on the platen glass plate 22 is read. To read the manuscript MS placed on the platen glass plate 22, the scanner 21 is moved to a position opposite the platen glass plate 22, reads the manuscript MS set on the platen glass plate 22 while scanning in a sub-scanning direction orthogonal to a main-scanning direction from a sub-scanning direction reference line B to acquire image data, and outputs the acquired image data to a control unit 7 illustrated in
When reading of the manuscript MS is instructed by the operation button 52 of the operation unit 5 in a state in which the manuscript MS is set on the manuscript placement unit 31, the manuscript MS fed by the manuscript feeding unit 3 is read. The manuscript MS is set on the manuscript placement unit 31 with its front surface (surface on which a manuscript image is read) facing up. Then, the manuscript MS set on the manuscript placement unit 31 is fed from a left side by the manuscript feeding unit 3, and the front surface of the manuscript MS is guided to a position opposite the manuscript reading slit 23. Further, to read the manuscript MS fed by the manuscript feeding unit 3, the scanner 21 is moved to a position opposite the manuscript reading slit 23, reads the manuscript MS via the manuscript reading slit 23 in synchronization with a conveying operation performed by the manuscript feeding unit 3 to acquire image data, and outputs the acquired image data to the control unit 7 illustrated in
The main body unit 4 includes a recording unit 6, a sheet feeding unit 41, a sheet feeding roller 42, a sheet conveying path 43, registration rollers 44, and delivery rollers 45. The sheet feeding unit 41 is a sheet feeding cassette in which a plurality of index sheets P are received, and the sheet feeding roller 42 draws out the index sheets P from the sheet feeding unit 41 one sheet at a time to the sheet conveying path 43. The index sheet P drawn out to the sheet conveying path 43 by the sheet feeding roller 42 is fed to the recording unit 6 by the registration rollers 44. The registration rollers 44 feed the index sheet P so as to align a leading edge of the index sheet P supplied from the sheet feeding cassette with a leading edge of an image read from a manuscript. Then, the index sheet P subjected to the recording by the recording unit 6 is delivered by the delivery rollers 45 to a delivery space 46 formed between the manuscript reading unit 2 and the main body unit 4. In this manner, the sheet feeding roller 42, the registration rollers 44, and the delivery rollers 45 function as a conveyance unit for the index sheet P.
The recording unit 6 includes a photoconductor drum 61, a charging unit 62, an exposure unit 63, an image forming unit 64, a transfer unit 65, a fixing unit 66, and a cleaning unit 67. The exposure unit 63 is an optical unit including a laser apparatus, a minor, and the like, and outputs and exposes a laser beam based on the image data to the photosensitive drum 61 that has been uniformly charged by the charging unit 62, to thereby form an electrostatic latent image on a surface of the photoconductor drum 61. The image forming unit 64 is a developing unit that develops the electrostatic latent image formed on the photosensitive drum 61 by using toner, and forms a toner image based on the electrostatic latent image on the photoconductor drum 61. The transfer unit 65 transfers the toner image formed on the photoconductor drum 61 by the image forming unit 64 onto the index sheet P. The fixing unit 66 heats the index sheet P onto which the toner image has been transferred by the transfer unit 65, to thereby fix the toner image onto the index sheet P. Then, toner remaining on the photoconductor drum 61 is removed by the cleaning unit 67.
The control unit 7 is an information processing unit such as a microcomputer including a read only memory (ROM) and a random access memory (RAM). A control program for performing the operational control of the image forming apparatus 1 is stored in the ROM. The control unit 7 reads the control program stored in the ROM, and expands the control program onto the RAM, to thereby control an entire apparatus in accordance with predetermined instruction information input via the operation unit 5. The printing processing unit 71 executes a printing operation in accordance with an instruction issued from the control unit 7. When a paper jam occurs in the conveyance unit (sheet feeding roller 42, registration rollers 44, and delivery rollers 45), the paper jam detection unit 72 detects the paper jam and notifies the printing processing unit 71 of the occurrence of a paper jam.
The storage unit 8 is a storage means such as a semiconductor memory or a hard disk drive (HDD), and stores the image data on the manuscript MS read by the scanner 21 along with various kinds of management information and setting information.
The communication unit 9 has the function of transmitting/receiving various kinds of data to/from a client apparatus 11 such as a personal computer (PC) and another image forming apparatus 1a via a network 10 such as a LAN. Further, the communication unit 9 is configured to be connected to the Internet 13 via the network 10 and a router 12. The communication unit 9 functions to transmit/receive various kinds of data to/from various kinds of communication equipment connected to the Internet 13.
First, the user causes an index sheet setting screen (not illustrated) to be displayed on the touch panel of the liquid crystal display unit 51, and sets index sheet information including an index label count, a print size, an index label interval, and an index label size. The set index sheet information is stored in the storage unit 8. Further, when an image is printed on an index label, the user causes an index label setting screen (not illustrated) to be displayed on the touch panel of the liquid crystal display unit 51, and sets index label information including the image to be printed on the index label, the format of a character when the image includes the character, and the layout thereof. The set index label information is stored in the storage unit 8. The user causes a paper jam handling pattern selection screen 80 illustrated in
In Step S101, the printing processing unit 71 acquires setting values set on the index sheet setting screen and the index label setting screen and stored in the storage unit 8, and uses the setting values set on the index sheet setting screen and the index label setting screen to set a toner fixing size in the fixing unit 66, a paper sheet interval in the sheet feeding roller 42, and the like.
In Step S102, the printing processing unit 71 sets an initial value of “1” in an index sheet counter (I) that counts index sheet being printed.
In Step S103, the printing processing unit 71 requests the reading of the manuscript MS using the manuscript feeding unit 3.
In Step S104, the printing processing unit 71 determines whether or not the manuscript MS has been normally read. When the manuscript MS has been normally read (Yes in Step S104), the procedure advances to Step S105. When the manuscript MS has not been normally read (No in Step S104), the manuscript MS is not set on the manuscript placement unit 31, and hence the printing process is brought to an end.
In Step S105, in a case of Yes in Step S104, the printing processing unit 71 extracts the (I)th index sheet P from the sheet feeding unit 41, and performs printing of the (I)th index sheet.
In Step S106, the printing processing unit 71 determines whether or not the paper jam occurrence in the (I)th index sheet P has been detected by the paper jam detection unit 72. When a paper jam has occurred in the (I)th index sheet P (Yes in Step S106), the procedure advances to Step S107. When a paper jam has not occurred in the (I)th index sheet P (No in Step S106), the procedure advances to Step S111.
In Step S107, in a case of Yes in Step S106, the printing processing unit 71 acquires the paper jam handling pattern No. from the storage unit 8. The printing processing unit 71 advances to Step S108 when the paper jam handling pattern No. is “1”, advances to Step S109 when the paper jam handling pattern No. is “2”, and advances to Step S110 when the paper jam handling pattern No. is “3”.
In Step S108, when the paper jam handling pattern No. is “1”, the printing processing unit 71 displays a paper jam display screen 91 illustrated in
In Step S109, when the paper jam handling pattern No. is “2”, the printing processing unit 71 displays a display screen 92 illustrated in
In Step S110, when the paper jam handling pattern No. is “3”, the printing processing unit 71 displays a display screen 93 illustrated in
In Step S111, in a case of No in Step S106, the printing processing unit 71 adds “1” to the index sheet counter (I), and returns to Step S103.
With the above-mentioned configuration, when a paper jam occurs while the index sheet is being printed, depending on the paper jam handling pattern selected by the user, it is possible to resume from the printing of the index sheet having the same format added instead of the index sheet that has caused the paper jam, to resume from the printing of the subsequent index sheet, or to cancel the printing. In this manner, the paper jam that has occurred can be handled in accordance with the paper jam handling pattern selected by the user before the print start. Therefore, for example, in a situation where an alternative index sheet is at hand, even when a paper jam occurs during the printing after the user selects a paper jam handling pattern “1” to start printing, it is not necessary to print only the index sheet that has caused the paper jam later. Further, in a situation where the alternative index sheet is not at hand, even when a paper jam occurs during the printing after the user selects a paper jam handling pattern “2” to start printing, it is possible to print the index sheets subsequent to the index sheet that has caused the paper jam in accordance with the user's settings. Further, in a situation where, for example, a person who wishes to use the image forming apparatus 1 next is waiting, when the user selects a paper jam handling pattern “3” and presses the “OK” button 92a, it is possible to easily cancel the printing of the index sheet. In addition, the index sheet counter (I) for the index sheet that has caused the paper jam is displayed on the paper jam handling pattern “1” display screen 91, the paper jam handling pattern “2” display screen 92, or the paper jam handling pattern “3” display screen 93, and hence the user can easily recognize a position in sequence of the index sheet that has caused the paper jam.
In another embodiment of the present disclosure, a printer driver 102c for the image forming apparatus 1 is installed on the client apparatus 11 such as a PC illustrated in
The functional configurations of the image forming apparatus 1 and 1a are the same as the functional configurations of the image forming apparatus 1 and 1a according to the previous embodiment.
The client apparatus 11 includes a computer 101, an auxiliary storage unit 102, an operation display unit 103, and a network communication unit 104, and those units are connected to one another via a bus or the like.

Further, the control unit 101a performs comprehensive control of the client apparatus 11 including various kinds of I/O, an interface such as a universal serial bus (USB), and a bus controller.
The printer driver 102c causes the computer 101 of the client apparatus 11 to function as a screen display unit 101b and a print instruction unit 101c. The screen display unit 101b displays the index sheet setting screen, the index label setting screen, and the paper jam handling pattern selection screen 80 according to the previous embodiment on the operation display unit 103. The print instruction unit 101c transmits the image data, and index sheet print setting data set from the index sheet setting screen, the index label setting screen, and the paper jam handling pattern selection screen 80 to the image forming apparatus 1 via the network communication unit 104.
The auxiliary storage unit 102 is an auxiliary storage apparatus formed of a flash memory, and stores the printer driver 102c and a program and data for processing to be executed by the computer 101. The auxiliary storage unit 102 includes an image data storing area 102a and an index sheet print setting data storing area 102b.
The image data storing area 102a stores the image data generated by the client apparatus 11, the image data on the manuscript read by the scanner or the like, and other such data.
The index sheet print setting data storing area 102b stores the index sheet setting screen, the index label setting screen, the setting data set from the paper jam handling pattern selection screen 80, and other such data.
The operation display unit 103 includes the operation panel, receives an input of the user's operation via the operation panel, and displays a result of the user's operation. Further, the operation display unit 103 displays the index sheet setting screen, the index label setting screen, and the paper jam handling pattern selection screen 80, and receives inputs of the user's settings.
The network communication unit 104 includes a detachably mountable LAN interface for connection to the network 10. The LAN interface includes a network unit that performs intelligent transmission/reception via various network protocols such as TCP/IP, AppleTalk, and SMB.
A description will now be provided of paper jam processing for the printing of the index sheet according to an embodiment. First, the screen display unit 101b displays the index sheet setting screen on the operation display unit 103 of the client apparatus 11. The user sets index sheet information including the index label count, the print size, the index label interval, and the index label size. The set index sheet information is stored in the index sheet print setting data storing area 102b of the auxiliary storage unit 102. Further, when an image is printed on the index label, the screen display unit 101b displays the index label setting screen on the operation display unit 103. The user sets index label information including the image to be printed on the index label, the format of a character when the image includes the character, and the layout thereof. The set index label information is stored in the index sheet print setting data storing area 102b of the auxiliary storage unit 102. Further, the screen display unit 101b displays the paper jam handling pattern selection screen 80 illustrated in
Subsequently, when the user uses the operation display unit 103 to start the printing of the index sheet, the print instruction unit 101c instructs the image forming apparatus 1 to perform printing. Note that, the index sheet P is set in the sheet feeding unit 41 of the image forming apparatus 1 in advance.
When printing of the index sheet is started, the control unit 101a acquires the image data from the image data storing area 102a, and acquires the index sheet print setting data from the index sheet print setting data storing area 102b. The print instruction unit 101c transmits the image data and the index sheet print setting data that are printing request data, to the image forming apparatus 1 via the network communication unit 104.
Subsequently, in the image forming apparatus 1, when receiving the printing request data, the printing processing unit 71 starts the printing process.
In Step S201, the printing processing unit 71 acquires the index sheet print setting data stored in the printing request data, and uses the index sheet information and the index label information to set a toner fixing size in the fixing unit 66, a paper sheet interval in the sheet feeding roller 42, and the like.
In Step S202, the printing processing unit 71 sets an initial value of “1” in an index sheet counter (I) that counts index sheets that are being printed.
In Step S203, the printing processing unit 71 acquires the image data from the printing request data. Note that, image data is acquired sequentially in units of pages.
In Step S204, the printing processing unit 71 extracts the (I)th index sheet P from the sheet feeding unit 41, and executes the printing of the index sheet.
In Step S205, the printing processing unit 71 determines whether or not a paper jam occurrence has been detected by the paper jam detection unit 72, to thereby determine whether or not a paper jam has occurred in the (I)th index sheet P. When a paper jam has occurred in the (I)th index sheet P (Yes in Step S205), the procedure advances to Step S206. When a paper jam has not occurred in the (I)th index sheet P (No in Step S205), the procedure advances to Step S210.
In Step S206, in a case of Yes in Step S205, the printing processing unit 71 acquires the paper jam handling pattern No. set on the paper jam handling pattern selection screen 80 and stored in the printing request data. The printing processing unit 71 advances to Step S207 when the paper jam handling pattern No. is “1”, advances to Step S208 when the paper jam handling pattern No. is “2”, and advances to Step S209 when the paper jam handling pattern No. is “3”.
In Step S207, when the paper jam handling pattern No. is “1”, the printing processing unit 71 transmits display request data on the display screen 91 illustrated in
In Step S208, when the paper jam handling pattern No. is “2”, the printing processing unit 71 transmits display request data on the display screen 92 illustrated in
In Step S209, when the paper jam handling pattern No. is “3”, the printing processing unit 71 transmits display request data on the display screen 93 illustrated in
In Step S210, in a case of No in Step S205, the printing processing unit 71 adds “1” to the index sheet counter (I), and returns to Step S203.
Note that, this embodiment is described by taking a situation where the printing request data on the index sheet is transmitted from the client apparatus 11 connected to the network 10 to the image forming apparatus 1 connected to the network 10, but the present disclosure is not limited thereto. For example, the printing request data on the index sheet can be transmitted from the client apparatus 11 connected to the network 10 to the image forming apparatus 1 connected to the Internet 13. Further, the printing request data on the index sheet can be transmitted from the client apparatus 11 connected to the Internet 13 to the image forming apparatus 1 connected to the network 10. Further, the printing request data on the index sheet can be transmitted from the client apparatus 11 connected to the Internet 13 to the image forming apparatus 1 connected to the Internet 13.
As described above, the user can request printing of the index sheet from the client apparatus 11. Further, when a paper jam occurs in the image forming apparatus 1 while the index sheet is being printed, the paper jam handling pattern “1” display screen 91, the paper jam handling pattern “2” display screen 92, or the paper jam handling pattern “3” display screen 93 is displayed on the operation display unit 103 of the client apparatus 11, to thereby allow the user to handle the paper jam from the client apparatus 11.
Note that, in the paper jam handling pattern No. “3”, as illustrated in
The image forming apparatus according to an embodiment of the present disclosure prevents wasteful printing due to deviation in sheet feeding when a paper jam occurs in the printing of the index sheet. Further, it is possible to provide an easy-to-use image forming apparatus by allowing the user to select a pattern of handling the paper jam.
