[Jamming] Jamcode 112F and jamcode 1011 on an external B1 finisher(iR-advC7055i)

[herlin]

I am bothered with a jamcode 1011 on external B1 finisher coupled to a ira7055i machine. Jam occurs once per 15 copies or so. When jam occurs the paper is located with leading edge to the sensorflag of S101, the one which says there is a delay jam, as if the feedroller before this sensor does not feed the paper at that time. Replaced the driving motor of this feedroller with no succes. Anyone having ideas? Maincontroller of the finisher???

Did u check the Error History
Run a History report and find where the 112F jam code coincides with an Error Code, troubleshoot this area.


Jam code 112F on a Finisher B1

Many issues may cause this code but this article will describe two items that were found to be specifically causing the code. In both cases the issue was resolved completely.
In one case the upper paper surface sensor actuator was broken. The part was replaced and this resolved the problem. See key # 4 in the image below. The part # is FC5-4162-020.

In another case, by observing the movement of the tray it was found that the upper paper surface sensor actuator key # 4, in the image above, was being activated by the Lower safety cover FC5-5443-020, this is key # 6 on figure (L15, Stack Upper Tray Assembly). See the image below. This is a long plastic piece that is attached to the middle tray by 2 small arms. The front arm came off and now the plastic piece was dangling too close to the finisher surface coming into contact with the upper paper surface sensor actuator, (Key #4, FC5-4162-020) when the tray would move up and down.


By re-attaching the Lower safety cover correctly, (Key # 6, FC5-5443-020), the problem was resolved.

In this case the machine was set to deliver the copy paper to tray B. If the unit is set to deliver copy paper to tray A the problem would not be apparent until the trays lifted when paper was being sent to one of the lower trays.

also-Adjust PI115 closer to the flag for the issue.


112F jam code is an error avoidance jam.
There were no error codes in service history.
Code would come up only when ruining multiple pages in the finisher. Single pages worked correctly. While watching the gripper unit it was noticed that the gripper unit did not grab the pages and exit them onto the finisher tray. Then the jam would occur. The gripper unit would not pull back into the finisher far enough to go behind the rear edge of the paper. The gripper unit need to go back all the way behind the stack of pages so it can close on the paper and push it forward to exit the stack out on to the tray.


In this case there was a push pin tack that had fallen into the gripper track. The tack prevented the gripper unit from moving all the way back causing the jam. The push pin tack was removed from the gripper track to resolve the issue.
