Media pass through mode for multi-engine system
View Patent ↗An integrated printing system is provided comprising a first image marking engine and a second image marking engine. The first and second image marking engines can be serially arranged with one another in a first operating mode. The first operating mode includes marking and passing of media to and from the first and second marking engines. A control system is provided for detecting a failure within one of the first and second image marking engines. A second operating mode is provided wherein the control system detects the failure and enables passing of the media through one of the first and second marking engines and marking of the media in another of the first and second marking engines when the failure is of a specified type.
1. An integrated printing system comprising:
a first image marking engine;
a second image marking engine;
said first and said second image marking engines serially arranged with one another in a first operating mode;
said first operating mode includes marking and passing of media to and from said first and second image marking engine;
a control system for detecting a failure within one of said first and said second image marking engines; and,
a second operating mode wherein said control system detects said failure and enables passing of said media through one of said first and second image marking engine and marking of said media in another of said first and second image marking engine when said failure is of a specified type.
2. The integrated printing system of claim 1 , wherein said failure is of a specified type selected from the group consisting of charging, exposing ROS, developing, transferring, fusing, and cleaning failures.
3. The integrated printing system of claim 2 , wherein said second operating modes includes cooling a fuser in one of said first and second image marking engines.
4. The integrated printing system of claim 1 , wherein said second operating mode includes opening a fuser in said one of said first and second image marking engines.
5. The integrated printing system of claim 4 , wherein said second operating mode includes cooling said fuser.
6. The integrated printing system of claim 1 , wherein said second operating mode includes cooling a fuser in one of said first and second image marking engines.
7. The integrated printing system of claim 1 , further including at least one media feed source for introducing media into said printing system.
8. The integrated printing system of claim 1 , further including at least one media finishing portion for receiving said sheets from said printing system.
9. The integrated printing system of claim 1 , wherein said first image marking engine is a first type and said second image marking engine is a second type.
10. The integrated printing system of claim 1 , wherein said first and second marking engines each include an internal duplex loop, such that when one of said first and second marking engines experiences a failure, the other of said first and second marking engines continues in both a simplex and a duplex mode.
11. A method of printing media for an integrated printing system, the method comprising:
providing a first image marking engine and a second image marking engine, said first and said second image marking engines serially arranged with one another in a first operating mode;
feeding media from a feed source into at least one of said first and second image marking engines during a first operating mode, said first operating mode including marking and passing of the media through said first and second marking engines; and,
changing to a second operating mode including marking of the media through one of said first and second image marking engines and passing the media through both of said first and second image marking engines.
12. The method of printing media according to claim 11 , further comprising: providing a control system for detecting a failure within one of said first and said second image marking engines wherein said control system enables said second operating mode upon detecting said failure.
13. The method of printing medial according to claim 11 , wherein enabling said second operating mode further includes opening a fuser in said one of said first and second image marking engines.
14. The method of printing medial according to claim 13 , wherein enabling said second operating mode further includes cooling said fuser.
15. The method of printing media according to claim 11 , wherein enabling said second operating mode further includes cooling a fuser in one of said first and second image marking engines.
16. The method of printing media according to claim 11 , further comprising: arranging said first image marking engine and said second image marking engine in a serial configuration with one another.
17. An integrated printing system comprising:
a first image marking engine;
a second image marking engine;
said first and said second image marking engines serially arranged with one another and having a first operating mode;
said first operating mode including marking and passing of media to and from said first and second image marking engines; and,
a second operating mode including passing of said media through one of said first and second image marking engines and marking of said media in another of said first and second image marking engines.
18. The integrated printing system of claim 17 , further including a control system for detecting a failure within one of said first and said second image marking engines; and,
said failure is of a specified type selected from the group consisting of charging, exposing, ROS, developing, transferring, fusing, and cleaning failures.
19. The integrated printing system of claim 17 , wherein said second operating mode includes opening a fuser in said one of said first and second image marking engines.
20. The integrated printing system of claim 19 , wherein said second operating mode includes cooling said fuser.
21. The integrated printing system of claim 17 , wherein said second operating mode includes cooling a fuser in one of said first and second image marking engines.
