    Cleaning developing roller on a Canon IR2525

    Good Afternoon,
    I have a customer that has a dark image on the copies on a Canon IR2525.
    I replaced the drum but the images were still there...seems like on the developing cylinder.
    Can I clean that? and how would you so as not to damage the developing unit?
    How would I do that?
    Thank you
    Doug

          I never clean the dev cylinder, it is either good or shot. I would be looking elsewhere for the problem. Is it a smear, streak, or offset image?

              Is it safe to guess that this Canon is monocomponent? If yes, what about mottling?

              Common on monocomponent developing, sometimes the toner clumps on the developing roller, especially during times of high humidity. Traditionally you would dry-wipe the developing cylinder with toner left in the unit. The toner just pushes out of the way. Keep wiping, rotating, wiping, rotating ... until you get all the way around.

              Aftermarket toner has a much worse problem with mottling. =^..^=
              If you'd like a serious answer to your request:
              1) demonstrate that you've read the manual
              2) demonstrate that you made some attempt to fix it.
              3) if you're going to ask about jams include the jam code.
              4) if you're going to ask about an error code include the error code.
              5) You are the person onsite. Only you can make observations.

                  Mono component Canon....I clean dev cylinders all the time. It was mandatory on NPs....just wipe them with clean dry cloth. If toner is baked to cylinder, scrape it loose with fingernail then wipe with dry cloth. Been doing this to Canon mono dev cylinders forever...older NPs I would wipe away toner coating and clean cylinder with Soft Scrub(except ones with black coating)

                      I would guess this poster is not using genuine toner, hence an issue with copy quality & the dev unit.
