Have a couple of these units that get heavy backround, changed developer and drum but no change. Have cleaned all the good stuff. Any thoughts? I have heard that these units may get build up on mag roller, does it need special help?

Re: MP 5001 5002
It's the #1 issue with these series either wire brush off the mag roller or replace the entire Dev. unit.Comment

Re: MP 5001 5002
Charge roller? Did you thoroughly clean the charge roller bushings? Was the DV initialized Properly? Are you using OEM Parts and supplies? Are you charge settings way out of wack? Is your transfer unit shot or plugged in backwards? Is your id senor clean and is your td senor good? Is the quenching lamp strip clean? Are your optics clean? Is there a good ground for the drum? I'm gonna need more info.Live for something or die for nothing.Comment

Re: MP 5001 5002
Check the development roller. If it is filmed, cleaned it. If it films up again, replace the development unit and developer, completely clean all toner from the PCU.Comment

Re: MP 5001 5002
There must be hundreds of posts on this site for the problem you are having. Very very common issue with this series. Reposting the following advice:
MP4000/5000/4001/5001 FixThis is what I do for the MP4000 and MP4001 series copiers. This seems to work well but it doesn’t prevent the problem completely. The problem is with the toner which Ricoh has stated but this seems to be very effective at preventing the overtoning.
The first step usually is to vacuum the pig out. Separate the development units, pull the drum and clean it out as best as you can. Try and get out as much toner as possible. On top of the unit there is a toner recycling auger that needs to be cleaned as well.
Take the screws out on top and carefully (the tabs break easily) remove the top of the drum unit and clean inside.
Verify that the development unit is the new unit (old one has one big vent hole and new ones have three vent holes and extra grounding tabs) and then try and clean the mag rollers. If they cannot easily be cleaned then the whole unit must be replaced because scotch bright cannot be used on these. It will clean it but the coating will be removed and they will cover with toner very quickly. Also you are not able to order just the mag rollers for this model due to factory gapping that cannot be done in the field. There is a part number but if you place an order for it, Ricoh will cancel the order and send you a message stating the same thing I just did. I know because I tried it.
Ricoh passed out a bulletin stating that it’s better to take out the second cleaning blade due to drum life, they also don’t include them in the kits or with new machines now. You don’t have to do this but I always add the second cleaning blade back into these machines, because in my tests the machine ran cleaner with the blade in.
Now that you have a new or clean unit pour in the new developer, place a piece of paper over the entrance hole to the development unit and reattach the development unit to the drum unit.

In SP modes there are two voltages Ricoh states needs to be changed. They are 2201-001 and 2201-002. Increase both of these by 100.
There is a method for testing drum ground on these machines but the ones that I did test failed badly so I have been adding this extra grounding strap to all of the machines. On the back you can easily see the drum shaft and can easily attach the grounding strap from the motor shown to the drum shaft.The drum grounding strap shown in the picture was discontinued and deleted by Ricoh but you can easily find a substitute. This was actually a strap from an older machine that had a drum grounding problem as well. Just a slight modification and it helped solve overtoning on this machine.
Apply a conductive grease to the shaft before adding the strap to help better ground the shaft.
After this has been completed then reinstall the PCDU unit and make 13 skyshots with a one inch lead edge to prevent jams in the fuser. This will help drop the density down in the new developer.
I usually have the machine in SP modes throughout the whole process to prevent any problems with print jobs or faxes trying to come through. After you run your skyshots initialize the developer then the run you ID sensor pattern. If the machine codes don’t panic, just open the front door, reboot and finish where you left off. It has only happened to me one time out of all the machines I have done.
The work is now done, remove the paper you installed between the drum unit and development unit (careful because there is usually toner on it) and run an SMC report for a test print.
Another thing to remember on this machine is every PM you have to change the Developer.

Re: MP 5001 5002
Thanks for the tips, I have been doing some of that stuff but not the grounding. I sure this will do it. Let you know.Comment

Re: MP 5001 5002
There is a fix for this but you'll need to speak with your Service Manager first and do your own testing. The problem is caused by the Ricoh toner - running these machines on the previous generation toner will make a huge improvement.
You'll need a DSM645 toner bottle drive motor (the drive is different), DSM645 dev and DSM645 toner. Strip and thoroughly clean the toner hopper, dev unit and toner recycling system then follow the standard set up from there. No more scrubbing dev cylinders at every call, short dev life, constant PCQ calls, and dirty machines

Would totally agree with this. Have multiple MP5001 copiers on site and all have had this done and problem has gone.There is a fix for this but you'll need to speak with your Service Manager first and do your own testing.
