I had a call on an MPC 2500 this afternoon, usual thing, black lines about an inch and a half wide down the edge of the copy. The drum looked mint and cleaning the charge roller made bugger all difference, so I swapped the charge roller into one of the colour PCUs to confirm it was the culprit, and it was. As I didn't have a replacement PCU on me I took the charge roller out of an old PCU I had in the van which had been replaced for the same reason, it was one of the new brown-ish type charge rollers, and I cleaned off all the brown coating with meths. It took a few minutes, gave the cleaning roller a blast with the air duster and put it back in the machine. The result - perfect copies. Couldn't give it a thorough test because the customer was waiting to go home, but ran about 100 copies through it and they were all spot on.
Just wandering if anyone else has tried this before and if so how long did it prolong the life of the PCU?
