anyone?
Have you tried adjusting the Buckle with SP 1003-002 for Tray 1 (Plain)? I know you said all 4 Trays exhibit the same problem but its worth a try. Tray 2/3/4 all are adjusted with SP 1003-007 (Plain).
Yes.
But it is solved....
At least, for the client it is solved...
I have swapped the entire duplex unit and took the problem back to our office
So, it's something in the duplex unit; i guess a wire is blocked, i will investigate this when i have more time.
I'll keep you informed.
Thanks to you for your input.
The problem was somewhere in the paper transfer & separation unit.
I've swapped and replaced so many things on the paper trans&sep unit that i can't get head nor tail of it, now!
I've noticed that a paper transfer & sep unit of a mpc3002 will give light image on the duplex side when used in a mpc5502.
The duplex units ass'y are inter swappable between these two models, but the mpc5502 paper trans&sep unit needs to stay with his model.
A mpc5502 paper trans&sep unit is ok in c3002, but not v.v. !!
Sorry.
- It is not solved. Whatever paper Tra&sep unit this duplex unit holds, it jams.
But this morning it all worked fine, so i assembled all panels and tested it afterwards (to be 100% sure), and the problem went back.
So, i removed all panels again, no good.
- The image of the duplex side is very much to light (i think there was no current to attract the toner from the ITB)
The image on all papers has moved upwards a bit.
The paper jams always at the same spot: one specific fork of the exit junction gate pawl.
The problem must be somewhere in the duplex unit itself; i checked for blocked wires, can’t see one.
But, the harness of the manual feed on these models are very vulnerable, when moving manual feed table, but even that one seems to be good.
...
After better inspection, there is one grey 12V wire that has a L angle and it seems that it was blocked before.
Could this cause such big problems?
Replace the fuser unit, or flip it on both sides, or secondary transfer.
