Ricoh MPC3003 finisher curls first page on double sided staple jobs

[Polarbear]

We have an MPC3003 with the floor standing finisher installed. This specific machine, does, intermittently, curl over the first page of a double sided staple job (as per the attached photos).Eventually the machine stops with a misfeed condition.

We have replaced the finisher (at the customer's request) and when the problem persisted, we even ordered and replaced the finisher with the booklet maker model, thinking that it might solve the problem.

Thus far we have not been able to make any improvement, after specialists and field supervisors have spent days checking the machine and not coming away with a permanent solution.

The customer (understandably) is getting very hot under the collar at present and is making demands about the permanent fixing of this issue.

Can anyone assist with this, or has anyone come across this already?

The problem is the paper.

The problem is the paper.

I agree!! try new paper of a different brand.

We have tried fresh paper from various suppliers. At this poi t I am thinking it has to do with the receiving tray somehow, as the paper collides with it on exit and most times only the first page turns over but sometimes a few turn over at once and then the machine stops with a jam condition.

Have you tried watching it with the door open and switch cheated? I would think that if you can watch it happen you would get a better idea of how it is occurring.

The 02s had a big problem with page curling into bridge units (folded corners), have not seen that happen to the newer 03s. I have seen this kind of curl on 03s with no finisher, replacing the paper exit (part # has recently changed) seemed to cure the problem.

Is it only on duplex copies that it curls in the finisher? I have had a similar problem that originated from the duplex section of the copier.

Sorry, that still looks like a poor paper problem, which is exactly what it has looked like for years.
Then again, I'd like to see if there is something that we may have missed here.
I'm guessing you have tried running the machine without any finisher attached. What happened then? Did the paper exiting the machine lay perfectly flat?
Also, does that finisher use the rubber flappers (the kind of "L" shaped rubber parts that rotate counter-clockwise when viewed from the front of the machine) to draw the paper back into the finisher for stapling? If so, it is actually really important that you check their timing when you see something like this happening.

You're located in what is most likely a high humidity region. Have you tried putting in the optional tray heater? If the problem seems to be more predominate in the morning, try storing the paper in a sealed container overnight. You could try turning the paper over. All paper has a tenancy to curl. If the side that has the natural curl side up in the tray, it will curl in the direction you show when running duplex. Usually the amount of curl is greater when the curl side is toward the hot roller or sleeve on the second time through the fusing unit.

Thanks for the feedback guys! In total we have had 3 finishers on the 3003. 2 of the same and 1 booklet model with the same result ( which to me rules out the finisher but one never knows ).

It doesn't look like a damp paper problem to me as there is no significant curl or wave on the other sheets.
Does it ever occur with the first stapled set fed out? I am thinking that there could be excessive static in the paper which is causing the first sheet to stick to the previous stack as it's being fed out.

Yip Duke

only duplex staple sets. Single sided are fine. I am thinking it is a combination of paper curl and the angle of the receiving tray.

Deb has hit it right on the head, it's a static issue, is your finisher grounded correctly but installing the correct earth plates.

Is it on carpet or is a board installed under it?

There are massive changes to the firmware on the two finishers this could be, I would guess that.
Could you let us know:
1) Model of finisher?
2) Jam code that is being thrown?

Will have field tech pull smc report and report back
