This unit is at a field site office in the middle of no where . Not sure of how stable the power is but I imagine if it was too bad the machine wouldn't run at all . Copies and prints were very good when first installed a couple of weeks ago but now have faded to almost an illegible state . We have changed the black drum unit and cleaned all the pre charge rollers, cleaned the optics and laser seal glasses . but with no result . Any suggestions would be greatly appreciated .

Re: Ricoh mpc 3500 light printing and copies
It's possibly due to the quality and compatibility of toner powder. Did you use the original toner cartridge?
If you don't use the original toner cartridge, we suggest that you use toner cartridge with high quality. -

Re: Ricoh mpc 3500 light printing and copies
Is it just black that's causing the problem?
What does the colour test print look like?
You said you changed the black drum, but not the dev? What are the PM counters at?Comment

Have you cleaned the shield glasses? To me, a field site in the middle of nowhere means a high dust location. Clean the shield glasses and if that takes care of the problem, show the key operator how to clean them. Also while you are there, clean the ADF feed and sensors.Comment

Print: SP5990-006 Non-Default (Prints only SPs set to values other than defaults.) Somebody could change some settings. Print log and see if any SC codes are logged.
Never seen original Ricoh drum failed like that. Try force add black toner and see if there is a change. You could swap black drum with a colour one to test your theoryComment

Re: Ricoh mpc 3500 light printing and copies
The clue to your problem could be in the your first paragraph "site office" ! My experience of such places is that they are staffed by large gentlemen that can get a little heavy handed with photocopiers.
Lets try some basics, first stop the copier half way through printing an A3. Is the the image OK on the transfer belt but light on the paper? If so you have a problem with the transfer roller being out of line with the contact point on the image transfer belt. In my experience this is caused by knuckle draggers managing to bend the entire right hand door or its mounting points.At least 50% of IT is a solution looking for a problem.Comment

Re: Ricoh mpc 3500 light printing and copies
Just my two cents, a failed forced line adjustment would probably indicate either dirty ID sensors or not enough toner in the line adjustment patterns on the ITB that the ID sensors can see. I suppose you might check the charge and developer values in service mode SP2 to see if they are close to default, that's pretty easy and might indicate a high voltage problem is causing the lack of toner on the belt.Comment

Re: Ricoh mpc 3500 light printing and copies
Have you replaced the toner pump on it? Does it ever get to a "Please add toner" state? I have seen a couple copiers where the "Add toner" message was turned off in SP's. Just another thought.Comment

Re: Ricoh mpc 3500 light printing and copies
SP 3045 Toner End Detect has to do with reading/writing the RFID chip on the toner bottle. If you have a bottle with a bad RFID you can chamge 3045 and use the machine while you get another toner. You will still get toner out indication from the toner out and toner density sensors. You just won't get a toner low message at 17%.Comment
