Fig. 2 is the block scheme that the system architecture of imaging device is shown.Controller part 201 can be communicated by letter with engine control section 203 with principal computer 200.Controller part 201 receives image information and print command from principal computer 200.Controller part 201 is analyzed the image information that receives, be converted into bit data, and will print reservation for each thin slice by video interface 210 and order (reservation command), printing initiation command and vision signal to send to engine control section 203.
In response to the print command from principal computer 200, controller part 201 will be printed to keep to order and send to engine control section 203, in the moment that allows to print, will print initiation command and send to engine control section 203.In this case, according to instruction from principal computer 200, controller part 201 sends to paper delivery option control section 202 with controlling the relevant instruction of the use of option with paper delivery, sends to paper supply option control section 204 with controlling the relevant instruction of the use of option with paper supply.
Keep the order of ordering according to the printing that comes self-controller part 201, engine control section 203 is prepared to print, and waits for the printing initiation command of self-controller part 201.When receiving print command, the benchmark that engine control section 203 will provide outputting video signal regularly /the TOP signal delivers to controller part 201, and keep order and begin printing in response to printing.In addition, engine control section 203 output/TOPR signals, this signal provides the timing of the thin slice of waiting at the registration roller place being carried out again paper supply.When/when the TOPR signal became " very ", by paper supply option control section 204, controller part 201 paper supply instruction again sent to paper supply option input media.
Fig. 3 is the process flow diagram that the printing of engine control section 203 is shown.When receiving printing reservation order, engine control section 203 is waited for and is received printing initiation commands (501), and pre-service (hereinafter referred to as " pre-rotation program (sequence) ") (502) is carried out in printing.After finishing the pre-rotation program, engine control section 203 output/TOP signals, and keep order beginning printing (503) in response to the printing of first thin slice.Receive next printing reservation order (505) before unless engine control section 203 begins regularly (being called " normally the printing beginning regularly ") in next printing, otherwise enter step 509 to keep handling capacity.In step 509, engine control section 203 is carried out the aftertreatment (hereinafter referred to as " post processor ") of printing, and finishes printing.When normally print beginning regularly at the next one before, engine control section 203 has received to be printed when keeping order and should printings keeping the printing initiation command of ordering, and begins the printing (506 and 503) of first thin slice, second thin slice afterwards.When normally print beginning regularly at the next one before, engine control section 203 has received to print and has kept order, but do not receive when printing initiation command, then carry out back rotation (post-rotation) program, enter and print initiation command waiting status (507 and 508), print initiation command to wait for receiving.When receiving the printing initiation command, engine control section 203 beginning pre-rotation (pre-rotation) programs (502).
Under Fig. 4 is illustrated in and hockets the situation of paper supply from paper-supply section 1 and two-sided device, the communication sequence till the duplex printing of beginning the 4th thin slice.The reservation order that controller part 201 will keep ID=1 sends to engine control section 203, with 311 from paper-supply section 1 paper supply, and paper is outputed to two-sided device; 312, send to keep the reservation order of ID=2, with from paper-supply section 1 paper supply, and paper outputed to two-sided device.313, controller part 201 sends the reservation order that keeps ID=1, with from two-sided device paper supply, and paper is outputed to the paper delivery part that is positioned at this device outside.Keep ID for remaining and repeat these operation stepss (314,315,316,317 and 318).Subsequently, 319, in response to keeping order, controller part 201 203 pairs of indication engine control sections keep ID to begin to print, and engine begins printing.Receive print initiation command after, engine control section 203 general/TOP signals and/the TOPR signal offers the controller part 201 of imaging sequence with formation image (320 and 321).On the other hand, with/the TOP signal Synchronization, controller part 201 outputting video signals, and be the next ID of reservation output print initiation command.Carry one in passing, shown in 311～318 reservation order,, below be referred to as " two-slices is alternately two-sided " for hocketing on the two-sided device from paper-supply section 1 with from the paper supply of two-sided device by a stand-by thin slice is placed on.
Fig. 5 illustrates the imaging sequence that forms image according to the duplex printing communication sequence among Fig. 4.In the duplex printing below, for the thin slice of supplying with and output to two-sided device from carton, its surface of having carried out printing for the first time is called " first face ", its reverse side is called " second face ", on this reverse side, when two-sided device is supplied with this thin slice, printing, and this thin slice is being outputed to the outside of imaging device.When receiving the printing initiation command (print ID=1) relevant with first printing reservation order of first thin slice, engine control section 203 beginning pre-rotation programs.After finishing the pre-rotation program, engine control section 203 output/TOP signals (100-1-S) beginning the printing of first thin slice, and are transported to two-sided device (101-1-S) with thin slice from carton.With/the TOP signal Synchronization, controller part 201 offers engine control section 203 with the beginning imaging with video data.Engine control section 203 utilizes alignment sensor 19 to carry out timing between the image that is transferred to from the thin slice of carton supply and by imaging moiety on the intermediate transfer body and regulates.Regulate by carrying out timing, engine control section 203 output/TOPR signals, and resupply thin slice, to transfer images to (102-1-S) on this thin slice.Make the thermal image photographic fixing that is transferred on the thin slice by photographic fixing part 13, and go out paper sensor 20 by photographic fixing.Therefore, finish and on first of first thin slice, carry out imaging (103-1-S).
Equally, when receiving the printing initiation command (print ID=2) relevant with first printing reservation order of second thin slice, engine control section 203 output/TOP signals (100-2-S) are to begin first printing of second thin slice.Therefore, thin slice is transported to two-sided device (101-2-S) from carton, and output/TOPR signal (102-2-S).Subsequently, 13 pairs of images of finishing to be transferred on the thin slice of photographic fixing part carry out hot photographic fixing.Thin slice goes out paper sensor 20 by photographic fixing, finishes imaging (103-2-S) on first of second thin slice.
Then, when receiving the printing initiation command (print ID=1) relevant with second printing reservation order of first thin slice, engine control section 203 output/TOP signals (100-1-D) are to begin second printing of first thin slice.Therefore, carry thin slice (101-1-D) from two-sided device, and output/TOPR signal (102-1-D).Subsequently, 13 pairs of images of finishing to be transferred on the thin slice of photographic fixing part carry out hot photographic fixing.Thin slice goes out paper sensor 20 by photographic fixing, finishes imaging (103-1-D) on second of first thin slice.First and second all through the thin slice of imaging by going out paper sensor 28, and output to the outside of imaging device.4 thin slices are repeated top operation, after finishing whole imagings, carry out the back rotation program once more, enter the waiting status of printing initiation command then.
Fig. 6 illustrates basis at the communication sequence before the duplex printing of beginning the 4th thin slice under the situation that paper-supply section 1 and two-sided device from Fig. 4 replace paper supply, in the imaging sequence of carrying out in conjunction with Fig. 5 explanation, when the imaging sequence of the thin slice that is positioned at paper-supply section 1 when the 4th thin slice uses up.In this case, can not proceed to print.Although first of engine control section 203 output the 4th thin slice /TOP signal (100-4-S), and continue second imaging of first thin slice, the 4th thin slice uses up.Therefore, there is not thin slice to be transported to two-sided device (101-4-S) from carton.When the thin slice in the carton had used up, the sensor that is positioned at the paper supply groove of paper-supply section 1 arrived no paper (paper-out), and notification engine control section 203.Like this, engine control section 203 has or not the thin slice state to be set to not have paper.In addition, because no paper appears, so the misprint that engine control section 203 will take place because of no paper is notified to controller part 201 (110).When no paper took place, engine control section 203 was proceeded imaging operation, up to second of second thin slice.In other words, engine control section 203 is notified to controller part 201 with following thin slice feed status, promptly stops thin slice when second face of second thin slice has gone out paper sensor 20 by photographic fixing and output to imaging device outside and carries (103-2-D).
Misprint takes place in engine, and the thin slice feed status of engine is when becoming in the non-conveying (not-in-transit), it is as follows that controller part 201 determines to recover (printing again) required printing ID.Specifically, by receiving registered reservation ID, the ID relevant with the paper of supplying with from paper-supply section from engine control section 203 and being used to the ID that begins to print, controller part 201 determines to recover (printing again) required printing ID.In the example of Fig. 6, (in-printing) ID according to (in-paper-feed) ID in the reservation ID of printing ID shown in Figure 7, the paper supply and in printing is judged as and need carries third and fourth thin slice again.Remove order in response to the misprint that comes self-controller part 201, engine control section 203 is carried out misprint and is removed sequence.
About control the configuration of imaging operation by distribution ID, TOHKEMY 2001-088496 communique is illustrated it.
In traditional example, when detecting no paper and will be notified to controller part 201 owing to the misprint that no paper causes, and till corresponding at this moment output /when first and second the imaging of the printing ID of TOP signal has been finished, finish imaging operation.Then, engine control section 203 thin slice feed statuss are set in the non-conveying, and wait for the misprint of self-controller part 201 to remove.In this case, because the residue thin slice that has been printed of one side rests in the two-sided device,, be positioned at the residue thin slice that the single face of imaging device was printed with output after removing misprint so need handle.In addition, recover the printing ID of the thin slice that single face printed.
Utilize the example of Fig. 6 that this is described in detail.Because no paper misprint takes place in the 4th thin slice, so when second of second thin slice of the printing ID that has finished the single face (first face) that has early than the 4th thin slice imaging, the thin slice feed status is set in the non-conveying.At this moment, the 3rd thin slice of printing owing to single face rests in the two-sided device, so under the situation that only one side is printed, the 3rd thin slice is outputed to the outside of device.Therefore, for the 3rd thin slice of judging and simultaneously being printed early than no paper, controller part 201 must resend and keep order, with paper supply and single face printing once more, thereby realizes recovery.
In other words, owing to do not passing through under the situation of duplex printing, the 3rd thin slice is output to the outside of device, so the 3rd thin slice that single face is printed is wasted.

Embodiment
Describe the application embodiments of the invention in detail referring now to accompanying drawing.
Present embodiment is characterised in that, even no paper takes place during two thin slices replace two-sided sequence, still can carry out and finish second imaging to the thin slice of finishing the single face imaging and be in stand-by state in imaging device.In other words, propose the thin slice that the single face in a kind of two-sided device of avoiding waste is printed, and after correct the printing, it has been outputed to the method outside the device.Term " two thin slices replace two-sided sequence " is meant under the situation that the thin slice that a single face was printed is waited in two-sided device, is being controlled to picture when paper-supply section 1 and two-sided device replace paper supply.Carry one in passing, because the structure of this imaging device and basic operation be with above-described identical, thus omit its explanation at this, and the identical Reference numeral of accompanying drawing employing.
In the present embodiment, according to the control procedure of the program in the unshowned ROM, the CPU 211 that constitutes engine control section 203 controls.More particularly, the output of reference sensor 23～28, CPU 211 judges which position that is in transport path for current operation thin slice, perhaps which face among first and second of thin slice is carried out imaging.In addition, when when first thin slice that carries out imaging begins to count, CPU 211 grasps the number of pages of above thin slice.In engine control section 203, according to the control procedure (control procedure that comprises the Figure 12 that will be explained below) based on the program in the unshowned ROM, CPU
The operation of each parts of 211 control Printer Engines.
Fig. 8 illustrates the alternately communication sequence of paper supply according to described two thin slices of Fig. 4, in the imaging sequence of carrying out in conjunction with Fig. 5 explanation, and the imaging sequence in the time can not proceeding to print because the thin slice in the paper-supply section 1 uses up at the 4th thin slice place.When engine control section 203 receives the printing initiation command (print ID=1) relevant with first printing reservation order of first thin slice, engine control section 203 beginning pre-rotation programs.After finishing the pre-rotation program, engine control section 203 output/TOP signals (100-1-S) are as indicating the timing signal that video data is offered the timing of imaging moiety.Therefore, the printing of controller part 201 beginnings first thin slice, and make thin slice be transported to two-sided device (101-1-S) from carton.With/the TOP signal Synchronization, controller part 201 offers engine control section 203 with vision signal, and the beginning imaging.Engine control section 203 utilizes alignment sensor 19 to carry out timing between the image that is transferred to from the thin slice of carton supply and by imaging moiety on the intermediate transfer body and regulates.Regulate by carrying out timing, engine control section 203 output/TOPR signals, and supply with thin slice once more to transfer images to (102-1-S) on the thin slice.The image that is transferred on the thin slice by 13 pairs of photographic fixing parts carries out hot photographic fixing, goes out paper sensor 20 by photographic fixing then, therefore, finishes and carry out imaging (103-1-S) on first of first thin slice.
Equally, when receiving the printing initiation command (print ID=2) relevant with first printing reservation order of second thin slice, engine control section 203 output/TOP signals (100-2-S) are to begin first printing of second thin slice.Therefore, thin slice is transported to two-sided device (101-2-S) from carton, and output/TOPR signal (102-2-S).Subsequently, 13 pairs of images of finishing to be transferred on the thin slice of photographic fixing part carry out hot photographic fixing.Thin slice goes out paper sensor 20 by photographic fixing, finishes the imaging (103-2-S) on first of second thin slice.
Then, when receiving the printing initiation command (print ID=1) relevant with second printing reservation order of first thin slice, engine control section 203 output/TOP signals (100-1-D) are to begin second printing of first thin slice.Therefore, carry thin slice (101-1-D) from two-sided device, and output/TOPR signal (102-1-D).Subsequently, 13 pairs of images of finishing to be transferred on the thin slice of photographic fixing part carry out hot photographic fixing.Thin slice goes out paper sensor 20 by photographic fixing, finishes the imaging (103-1-D) on second of first thin slice.First and second all by the thin slice of imaging by going out paper sensor 28, output to the outside of imaging device.
During the double-sided recording modes of aforesaid 4 thin slices, although first of engine control section 203 output the 4th thin slice /TOP signal (100-4-S), and continue second face of first thin slice is carried out imaging, the 4th thin slice uses up.Therefore, there is not to be transported to from carton the thin slice (101-4-S) of two-sided device.When the thin slice in the carton had used up, engine control section 203 received no paper detection signal from the sensor of the paper supply groove that is positioned at paper-supply section 1, and has or not the thin slice state to be set to not have paper state (150).
In this case, even after detecting no paper, engine control section 203 is still exported the trilamellar second/TOP signal (100-3-D), at this moment because the 3rd thin slice that single face was printed is in stand-by state in two-sided device.After having exported trilamellar second/TOP signal, misprint will take place because of no paper and be notified to controller part 201 (151) in engine control section 203.
Do not have paper although engine control section 203 detects the 4th thin slice, for having exported at 100-4-S /the 4th thin slice of TOP signal, output/TOPR signal is to guarantee the couplings (102-4-S) such as timing of controller part 201 and imaging operation.
When having finished the trilamellar first and second 's imaging, and when thin slice had gone out paper sensor 20 by photographic fixing and be transported to imaging device outside, engine control section 203 thin slice feed statuss were set to (152) in the non-conveying.
In the present embodiment, use up even detect the 4th thin slice, engine control section 203 still according to print id information export the trilamellar second image /the TOP signal, and on intermediate transfer body 12, form the trilamellar second image.Then,, promptly be used for image is transferred to timing on the thin slice from middle transfer article 12 in order to be adjusted to picture regularly, 203 outputs of engine control section be used for transfer printing the 4th thin slice first image /the TOPR signal.Subsequently, the image that engine control section 203 output the is trilamellar second /the TOPR signal, be transferred on the thin slice with trilamellar second image that will on intermediate transfer body 12, form.
Therefore, first image about the 4th thin slice, first image of engine control section 203 outputs the 4th thin slice /the TOPR signal, with by in the double-face imaging operation, keeping the alternately imaging order of 4 thin slices, the image on the intermediate transfer body correctly is transferred on the trilamellar second.Subsequently, trilamellar second image of engine control section 203 output the /the TOPR signal.
About first image of the 4th thin slice, under the normal condition that no paper does not take place, this image of formation before forming the trilamellar second image.Yet, because no paper takes place, so stoped its formation on intermediate transfer body 12.More particularly, engine control section 203 carries out following control.At first, although in response to/the TOP signal, engine control section 203 receives the view data that slave controller part 201 sends, and its prevention is luminous from scanner (10Y, 10M, 10C, 10K), goes up imaging to stop in photosensitive drums (5Y, 5M, 5C, 5K).
Subsequently, engine control section 203 is controlled as follows, so as transfer images on the trilamellar second that resupplies from two-sided device and it is outputed to the outside of device after stop imaging.Alternatively, about first image of the 4th thin slice, can form this image and do not forbid the luminous of scanner.Yet in this case, transfer roll 9 must be positioned at position 9b (released state) so that transfer section (roll gap between intermediate transfer body and the transfer roll) is penetrating, utilizes cleaning device 21 to clean afterwards.
When the misprint that takes place to produce because of no paper in engine, and the thin slice feed status of engine is when becoming in the non-conveying, the required printing ID of controller part 201 definite recoveries.Specifically, by receiving registered reservation ID, the ID relevant with the paper of supplying with from paper-supply section from engine control section 203 and being used to the ID that begins to print, controller part 201 is determined the printing ID that recoveries are required.In the example of Fig. 8, ID according to ID in the reservation ID of printing ID shown in Figure 9, the paper supply and in printing determines only to need to carry again the 4th thin slice.Remove order in response to the misprint that comes self-controller part 201, engine control section 203 is carried out misprint and is removed sequence.In conventional example, because simultaneously the 3rd thin slice that has been printed rests in the two-sided device as the residue thin slice, so need be used for after removing misprint, exporting remaining trilamellar processing.Before not having the paper judgement, the 3rd thin slice is carried out paper supply, and it is carried out single face print.In conventional example, also recover the printing ID of the thin slice of single face printing.Yet, in the present embodiment, finish behind the double-face imaging till the 3rd thin slice of single face printing end of output.Therefore, need not to carry out extra paper delivery handles.In addition, owing to reduced the quantity of the thin slice that will recover, so avoided the waste of thin slice.
Yet in the present embodiment, engine control section 203 output is in the timing signal (/TOPR signal) of first image of the 4th thin slice of no paper, to regulate the transfer printing timing of the trilamellar second image.This makes on second of thin slice of the printing of single face that imaging device with intermediate transfer body as present embodiment described in can be during remaining in this device correctly formation image, and with its output.
Present embodiment is characterised in that, even during the alternately double-face imaging of 3 thin slices no paper takes place, still can carry out the thin slice of simultaneously having finished imaging and be in stand-by state in imaging device and finishes second imaging and do not break down.In other words, propose the thin slice that the single face in a kind of two-sided device of avoiding waste is printed, and after correct the printing, it has been outputed to the method for device outside.Term " 3 thin slices replace two-sided sequence " is meant under the situation that two thin slices are waited in two-sided device, is being controlled to picture when paper-supply section 1 and two-sided device replace paper supply.Carry one in passing, because the structure of this imaging device and basic operation be with above-described identical, thus omit its explanation at this, and the identical Reference numeral of accompanying drawing employing.
Figure 10 is illustrated in according to 3 thin slices and replaces two-sided sequence when carrying out the double-face imaging sequence of 5 thin slices, the imaging sequence in the time can not proceeding to print because the thin slice in the paper-supply section 1 uses up at the 4th thin slice place.When engine control section 203 receives the printing initiation command (print ID=1) relevant with first printing reservation order of first thin slice, engine control section 203 beginning pre-rotation programs.After finishing the pre-rotation program, engine control section 203 output/TOP signals (200-1-S) to be beginning the printing of first thin slice, and thin slice is transported to two-sided device (201-1-S) from carton.With/the TOP signal Synchronization, controller part 201 offers engine control section 203 with vision signal, and the beginning imaging.Engine control section 203 utilizes alignment sensor 19 to carry out timing between the image that is transferred to from the thin slice of carton supply and by imaging moiety on the intermediate transfer body and regulates.Regulate by carrying out timing, engine control section 203 output/TOPR signals, and supply with thin slice once more to transfer images to (202-1-S) on the thin slice.Make the thermal image photographic fixing that is transferred on the thin slice by photographic fixing part 13, and, therefore finish and on first of first thin slice, carry out imaging (203-1-S) by photographic fixing feed in sensor 20.
Equally, when receiving the printing initiation command (print ID=2) relevant with first printing reservation order of second thin slice, engine control section 203 output/TOP signals (200-2-S) are to begin first printing of second thin slice.Therefore, thin slice is transported to two-sided device (201-2-S) from carton, and output/TOPR signal (202-2-S).Subsequently, 13 pairs of images of finishing to be transferred on the thin slice of photographic fixing part carry out hot photographic fixing.Thin slice goes out paper sensor 20 by photographic fixing, finishes the imaging (203-2-S) on first of second thin slice.
3 thin slices replace two-sided in, also receiving when keeping the relevant printing initiation command of order (printing ID=3) with the trilamellar first printing, engine control section 203 output/TOP signals (200-3-S) begin trilamellar first printing.Specifically, engine control section 203 is transported to two-sided device (201-3-S) with thin slice from carton, output/TOPR signal (202-3-S).Subsequently, 13 pairs of images of finishing to be transferred on the thin slice of photographic fixing part carry out hot photographic fixing.Thin slice goes out paper sensor 20 by photographic fixing, finishes imaging (203-3-S) on the trilamellar first.
Then, when receiving the printing initiation command (print ID=1) relevant with second printing reservation order of first thin slice, engine control section 203 output/TOP signals (200-1-D) are to begin second printing of first thin slice.Therefore, carry thin slice (201-1-D), output/TOPR signal (202-1-D) from two-sided device.Subsequently, 13 pairs of images of finishing to be transferred on the thin slice of photographic fixing part carry out hot photographic fixing.Thin slice goes out paper sensor 20 by photographic fixing, finishes imaging (203-1-D) on second of first thin slice.First and second all by first thin slice of imaging by going out paper sensor 28, output to the outside of imaging device.
During the double-sided recording modes of aforesaid 5 thin slices, although first of engine control section 203 output the 4th thin slice /TOP signal (200-4-S), and begin second imaging of first thin slice, the 4th thin slice uses up.Therefore, not having can be from the 4th thin slice (201-4-S) of carton conveying.When the thin slice in the carton had used up, engine control section 203 received no paper detection signal from the sensor of paper-supply section 1, and had or not the thin slice state to be set to not have paper state (250).In this case, even after detecting no paper, engine control section 203 is still exported second and the trilamellar second/TOP signal (200-2-D and 200-3-D), and this is because the second and the 3rd thin slice printed of single face has been in stand-by state in two-sided device.
After having exported trilamellar second/TOP signal, misprint will take place because of no paper and be notified to controller part 201 (251) in engine control section 203.In addition, although the 4th thin slice uses up, engine control section 203 is output/TOP signal (200-4-S, 200-5-S) still.Then, for having exported /the the 4th and the 5th thin slice of TOP signal, engine control section 203 output/TOPR signals are to guarantee the couplings (202-4-S, 202-5-S) such as timing of controller part 201 and imaging operation.
After having notified misprint, with second image of second thin slice /first image of TOPR signal, the 5th thin slice /TOPR signal and trilamellar second image /order of TOPR signal, engine control section 203 output/TOPR signals.Then, when having finished second and trilamellar first and second 's imaging, and when each thin slice had gone out paper sensor 20 by photographic fixing and be transported to imaging device outside, engine control section 203 thin slice feed statuss were set to (252) in the non-conveying.
In the present embodiment, even detecting the 4th thin slice uses up, engine control section 203 still according to print id information export second thin slice second image /TOP signal and the trilamellar second image /the TOP signal, and on intermediate transfer body 12, form second thin slice and the trilamellar second image.
Then, in order to be adjusted to picture regularly, promptly the two-sided alternately imaging operation by keeping 5 thin slices is transferred to timing on the thin slice, engine control section 203 output next signals with image from middle transfer article 12.Specifically, output is used for first image of transfer printing the 4th thin slice/TOPR signal and first the image that is used for transfer printing the 5th thin slice/TOPR signal.
As mentioned above, with first image of the 4th thin slice /second image of TOPR signal, second thin slice /first image of TOPR signal, the 5th thin slice /TOPR signal and trilamellar second image /order of TOPR signal, engine control section 203 output/TOPR signals.Therefore, can transfer images to second and the trilamellar second on.
By such output/TOPR signal regulate on the intermediate transfer body imaging regularly, can be supplied with and be arrived the timing of transfer position at the thin slice that single face is printed once more, correct transfer printing is formed on the image on the intermediate transfer body.
About first image of the 4th and the 5th thin slice, under normal condition, it forms before forming second image of second thin slice and before forming the trilamellar second image respectively.Yet, owing to after the 4th thin slice, do not had paper, so stop it on intermediate transfer body 12, to form.More particularly, although in response to/the TOP signal, engine control section 203 receives the view data that slave controller part 201 sends, and stops scanner (10Y, 10M, 10C, 10K) luminous, goes up imaging to stop in photosensitive drums (5Y, 5M, 5C, 5K).
Subsequently, engine control section 203 is controlled as follows, so as transfer images to supply with once more from two-sided device second and the trilamellar second on and it is outputed to the outside of device after stop imaging.
Carry one in passing, about first image of the 4th and the 5th thin slice, it can be formed on the intermediate transfer body, and does not forbid its formation.In this case, transfer roll 9 must be positioned at position 9b (released state) so that transfer section (roll gap between intermediate transfer body and the transfer roll) is penetrating in case spline prints on the record sheet, utilizes cleaning device 21 to clean afterwards.
When the misprint that takes place to produce because of no paper in engine, and the thin slice feed status of engine is when becoming in the non-conveying, the required printing ID of controller part 201 definite recoveries.Specifically, by receiving registered reservation ID, the ID relevant with the paper of supplying with from paper-supply section from engine control section 203 and being used to the ID that begins to print, controller part 201 is determined the printing ID that recoveries are required.In the example of Figure 10, ID according to ID in the reservation ID of printing ID shown in Figure 11, the paper supply and in printing determines only to need to carry again the 4th and the 5th thin slice.Remove order in response to the misprint that comes self-controller part 201, engine control section 203 is carried out misprint and is removed sequence.With identical in conventional example, the second and the 3rd thin slice that one side is printed rests in the two-sided device.Therefore, need be used for residue second and the trilamellar processing that the output one side has been printed after removing misprint.The second and the 3rd thin slice that one side is printed is not have the thin slice of supplying with before the paper judgement, and its single face is printed.In conventional example, also recover the printing ID of the thin slice of single face printing.Yet, the thin slice of printing for the single face in the present embodiment, its by before the double-face imaging not with its output.Therefore, owing to do not remain the one side thin slice of imaging, handle so need not to carry out extra paper delivery.In addition, owing to reduced the quantity of the thin slice that will recover, so avoided the waste of thin slice.
In addition, in the present embodiment, engine control section 203 output is in the timing signal (/TOPR signal) of first image of the 4th and the 5th thin slice of no paper, to regulate the transfer printing timing of second and the trilamellar second image.Like this, described in present embodiment, have and correctly on second of the thin slice of being printed by single face that the imaging device of intermediate transfer body can be in remaining in device form image and its output.
