Ricoh MP C2800 Bleeding Magenta

I cleaned the machine the other day and its back again. I'm guessing drum unit but look for a possible solution from a pro...

Did you clean the Charge roller with water? you can normally get months and months more out of them before having to change the drum.
The older style drum's it just pops out after releasing a few plastic lugs. The newer drums you have to remove a couple of screws first.
5 minute job.

Cleaning this is like pissing your pants to keep warm in winter, just change the PCU.

There is a bulletin out on cleaning charge rollers. Once you have the roller assembly out of the drum unit, roll paper between the charge roller and the cleaning roller to keep the cleaning roller dry. Use a soft paper towel moistened with water only, do not get it too wet. If you have the older style drum unit, be careful to avoid damaging the bias contact that is on one end of the roller assembly. It must be in contact with the roller shaft or yo will get heavy background.

Interesting...

The charge roller acts like a capacitor to store and dissipate the charge across the drum evenly...I would think water would just dissipate with little to no restorative results! I have always used the NuFinish silicone based car polish which cleans as well as restore (to some degree) the capacitive properties of the charge roller!--you notice on the color charge rollers that the have "lines" running around the roller which are more often than not "blown out" and look burnt and oxidized from the ozone generation...the NuFinish can pretty much restore that!....don't forget to slip a piece of paper between the charge roller and cleaning sponge roller when doing this procedure!:

The Once-a-Year Car Polish | Nu Finish - Nufinish
I use the white liquid in the tall bottle...not the paste!

The only time I use water or a water based approach is with the B&W machines that have a truly black rubber charge roller!...and then most of the time, I use the SCRUBS cleaner towel to remove the scaly grime from the charge roller!:





PS--regarding the color machines, the charge roller cleaning is a "fix" for a drum unit section that seems to be "failing" prematurely...pay attention the yield count of the drum unit section and replace when appropriate!

PPS--also, I have noticed more charge roller problems, especially with Ricoh when there is a seasonal humidity change...winter-->spring & fall-->winter....just my 2c worth!

De Ink (the pink stuff) works GREAT (mixed with a little water) to clean charge rollers

Re: Ricoh MP C2800 Bleeding Magenta

try to removed and clean the two cleaning blade as they may have cake toner on the edge of blade.

Re: Ricoh MP C2800 Bleeding Magenta

If you haven't already, spli the drum and dev and check for toner build up between the units. This can drop randomly.
