Hi again,
This is becoming habitual, twice in a week!!
So, to the collective wisdom of the Ricoh forum, a new problem that has occurred is a feed issue with a MPC4502 adf. This is the ordinary df 3070 unit (not the single pass). I though I had seen everything possible on these adf units but we have one customer who has ongoing issues with the feeder taking four or five pages at once.
I have changed the reverse roller, the torque limiter and the df belt. I have checked that the reverse roller gear on the shaft is not split, and checked all the one way bearings, and cleaned all the sensors and rollers - In fact I have covered (I think) most of the usual issues, but it still does it.
We have even swapped the doc feed for a known good one too and it still did it, so I am leaning towards the issue being with the actual documents themselves, but for what its worth..
So a brief description of the fault;
Print smc report and COPY thru ADF - no jams - no multi feed issues.
Take user documents for SCANNING and put through adf, takes and separates first sheet and then drags subsequent 4 or 5 pages through at once.
SCAN the same five docs through the adf short edge feed and it copes ok.
The odd thing is that on the smc report it runs through and separates fine, but on the user docs to scan it multi feeds . Its as if the pages are literally "sticking" together.
The only thing I can think of is that as the SCAN function seems to run the adf quicker than the COPY function, perhaps a clutch is worn on the reverse roller drive or maybe static on their job is causing the problem? The other thing to note is that it doesn't register a jam at all when it does it.
And the oddest thing is that the machine downstairs is doing the same thing...........(Arrrgghhhh
Any input would be welcome
Regards
Steve
