Ricoh 1022 jams at reg roller and just says "copying"

[copyaction]

Pretty intermitant about once ever 50 or 100 copies, page will feed up to reg roller and stops, machine keeps cycling and just say "copying"
have to remove jam and turn power off to reset.
happens from both drawers.
just a copier no print, scan, fax or doc server.
replaced all 4 boards in back, still does it

Try increasing buckle. Replace clutches. I vaguely remember having this issue. If the sensor sees paper just before the reg roller but the reg does not pull it no jam is indicated.

[Black Cloud]

Oh yes and make sure the reg roller pinches on both sides. The pressure spring lever breaks on this model.

I have seen the finisher cause that. Does it have a finisher to unplug and test?

[copyaction]

It just has a shift sort tray and I tried running it without it but still same problem.
I also swapped the doc feeder just in case but that also didn't fix it.
I ordered the reg clutch so we will see when that comes in.

[copyaction]

Reg clutch did not fix it.

I also noticed that when it gets stuck in "copying" condition and I remove the jam at the reg roller and the sheet in the doc feeder, the doc feed jam will not clear unless I power the copier off and back on.

and as I said I have already tried a working doc feeder.

Check to see if the registration sensor harness is damaged. It is easy to get it trapped between the reg sensor guide plate and the reg roller rear bushing. The wire can break trough the insulation and short out.

OK, now replaced entire right side door assy including reg sensor and transfer roller assy.

still same problem but I noticed if I just let it sit there long enough while it just says "copying" it will eventually change to SC-193.

what else is left (besides replacing entire machine)

I would certainly update the firmware, if you have the capability. I think you have to use MCE and an IC card on this machine.

The problem is not caused by a jam.
Paper is stopped at the registration because the machine is not ready with its image data.
You replaced controller and IPU board ?
Are the any code logged on SMC data besides SC193 ?

[TonerMunkeh]

Might be the controller or HDD is stalling. Does the machine do or have either?

[copyaction]

yes I have another working machine and I replaced EVERY board in the back of the copier.
I guess I have to go with the op panel and lens/ccd next.

also there is no hdd on this one.

On Canon's with fluorescent exposure lamps you can get this symptom when the lamp intensity is too dim. Sometimes a bad lamp, sometimes a bad inverter, sometimes bad or shifting lamp heater, rarely a bad CCD or ribbon cable or intensity sensor. The Canon NP6650 will display "copying" with the motor running when the the fuse is blown on the motor controller board, or the motor controller board is blown.

On early Mita's you can get this symptom when the scanner cannot find home position to start the scan. Sometimes a frayed or loose scanner cable, sometimes a dirty or defective scanner home position sensor.

I don't know if any of this is applicable to your situation, on a Ricoh, but it sound like your getting desperate enough to try almost anything. Let me know if it helps. =^..^=

I think its the SBCU as i dont believe there is a independent ipu board on this model.

The problem is not caused by a jam.

first let me say thanks to everyone for all the suggestions.

I was able to see the problem when copying from the platen glass as well and the lamp would complete the scan and return to home position, and at that point the paper would feed to the reg roller and stop and the copier would just say copying.

I'm not sure which is the SBCU board but I have replaced all 5 boards on the back of the machine now including the lamp board at the top. Is the SBCU located somewhere else or would that be 1 of those 5?

at this point I'm going to try the exposure lamp etc. as I did get a couple SC 101's at power up.
