Ricoh 2105 weird jam problem.

[dalesamuels]

jam code 073

that is the duplex entrance sensor (staying on)

Just to confirm, the machine does this when you take multiple single sided copies from an original on the platen glass?

and you are still getting 073 jam codes?? are they face down? if they are they are still hitting that entrance sensor in the inverter, run an out put check on that duplex/inverter entrance sensor in SP7-804 or 803. the code is for the sensor staying on, so the paper is lagging or the sensor is faulty or dirty. try running a bunch face up and see if it still jams on you. maybe check any other codes in 'jam by location' the numbers listed corrispond to the codes. But the latest codes are the ones u need to check out. hopefully I'm being helpful. good luck

Do u have the gray background on internal prints? (meter sheet) laser window? and sometimes the mag roller gets coated with a film of toner, I usually scotchbrite it, that could cause a background. charge voltage should be about 1500v's see if that's way off, in SP-2's (drum).

??? if scanned from the glass, the copies should exit to the finisher proof tray face up. if these don't jam the problem is invertion / duplex related.

multifeeds

Hi guys, I have Ricoh 2105 that jams out of all trays, any size, not constantly. We have thrown brand new rollers in all trays and it did not help. It is pulling multiple sheets. Waching machine feeding looks like it feeds a sheet, takes one but sep. roller kicks second page back too far and then next feeding step takes several pages at once - it could take up to 4-5 sheets. Is there a speed of Sep roller adjustment or any other solutions please?
I had sprayed paper with antistatic spray to illuminate excess of static attraction - no real results
Thank you.

To fix the multifeeds on the 2105 you need to go into service mode and go to service program sp1907-001 and set the value from 0 to 10. Do this on all sp modes for 1907-001 to 007. This will put a 10 ms delay between each sheet being fed out of the tray which will reduce the multifeeds. You can go up to 20 if you are still getting multifeeds. If you don't have this sp in service then your firmware is out dated.
