C2800 Jam locations

[Jomama46]

Is there a bulletin that lists the additional jam location on this and the new machines. The manual list up to SP7504-109 and this goes all the way to -191. MIssing are codes -130 to 170. They are listed on the SMC printout but not in the book. JUst wondering if they ever corrected it. I also checked in the C4/5000 and the C3501. I think they are printed in China, that would explain it.

On the SMC report, are there location names next to the jam codes that aren't in the manual? Maybe they are universally reserved for accessories that wouldn't be used on this model?

Re: C2800 Jam locations

Yes named locations are there. The reason it came up is a tech was on a 2800 that had a 132 jam in the history. On the SMC list 132 is a shift motor error. Most of the missing codes had a EUR after them.as part of the finisher name.It would be natural to assume it means Europe but here it is. The finsher was a booklet type and I am home now but I think is was the SR3000.
Its not the first time things have been left out but usually they are correced with a TSB. Plus the c2800 is what, 3 generations back. No mention of the locations in the new machines either.

Re: C2800 Jam locations

This is pretty dumb, not being consistent with the documentation. I did find those codes listed in the MPC2000 sm under jam detection but not on later generations.

Re: C2800 Jam locations

Their the ones OK. Only the ones on the SMC were truncated so all I could see was Shift tray (something) and it led me to think it was the shift tray motor. Glad you found this, Paper not reaching the shift tray exit sensor is easier to understand.
Thanks for that teebee

Re: C2800 Jam locations

Still getting this jam 132. Very erratic, but each time, the paper is between the punch unit and the shift tray exit. The punch unit looks OK, no mylars or anything dragging. Rollers are clean.
Anybody experience this or have any ideas? We have replaced the shift tray exit sensor

Re: C2800 Jam locations

Does the jam occure with the first page of a job or after some sheets? I don't have the design of the exit sensor/actuator in my mind but maybe something is sticky and the sensor remains active after the sheet passed it.

PS: The locations are written in the SP tables but are missing in the other chapter - still the information is more or less in the manual

Re: C2800 Jam locations

It occurs in the middle of a run, This is a flat photoreflector sensor. no actuator. The position of the paper seems to correctly match the code. Paper not reaching the sensor or staying at the sensor.
Interestingly, the SR4020 uses that code but it means something entirely different, pointing to the stapler shift motor.
I am looking at some slipping roller perhaps.

Re: C2800 Jam locations

Have you tried changing the output to the proof tray and see if you still get an issue? Might help eliminate part to the drive. The last time I had a problem on this finisher was the 2 gate pawls (proof and staple) that are nested together was broken at the front hinge point, allowing the proof pawl to shift and flop. But in a situation like that I would expect you to be getting hard jams and be pretty obvious.

Re: C2800 Jam locations

We haven't tried that, its a good idea.

Re: C2800 Jam locations

Now its not looking like an electro mechanical problem at all, it still codes a 132 but only when the customer is using it. I think it when they print.
The tech out there now ran 800 copies to the proof and shift tray and it runs flawless. He plugged the nw cable in and it jammed or showed a jam, Im not sure which.
The type of finisher is automatically propagated to the driver so I dont think it can be that.
This is getting strange which means the answer is going to be very simple once discovered.
More later.
Input welcome.

Re: C2800 Jam locations

The problem was the shift roller motor. Wasnt moving at all.
