Hey guys and gals.... Could someone please tell me what the latest fix is on these machines. I am sick of cleaning charge rollers and useing up PCU's!!! If I could get the latest sp mode adjustments or whatever Ricoh is recommending that would be great. I see the charge rollers have changed material, but still haveing problem. Hey does anyone know of an aftermaket charge roller and cleaner assembly?????

to solve the problem (copiermaster.net)

1. Clean the lubrication bar surface touched brush
2. Clean the charge roller. But it should be totaly white. You must clean grey area from the charge roller.
3. Clean drum. If you do not have drum cleaner ı have very good one. I can write.

these actions will solve the problem.

This was causing us to here in sweden. due to weatherchange these lines shows up, and the only way to fix it was PCU change or open the right hatch on the machine to let the fuser cool down.

Some of our units dont even make it to 20,000 before the line problem comes up. Since we include the units in our maintenance we change the unit, disassemble the unit completly, clean the blades, chg roll , and drum under hot water. Dry completly with hair dryer. Vacuum all traces of toner from unit and then use it for the next one to be replaced. We keep records for each unit and when the unit approches 100,000 it gets trashed. A lot of work, but saves a lot of money. This is the only problem we have ever had on these machines.
