    IM C6500 to much yellow toner being used

    Hello, i have a customer with a Ricoh IM C6500 that is using up quite a bit of yellow toner in excess of two containers per month. Also, i am getting a yellow shade on the images. I have replaced the dev. unit, the drum cleaning assy. and the charge roller. Any ideas of how to control the amount of toner going into the dev. unit ?
    Regards

      usually this problem (even on lower models) occurs when the development unit is exhausted (I opened a discussion years ago on this) some say it is the pcu, and some say it is the development unit, the best and definitive solution is to replace both at the same time

          The yellow shade is the problem. It is pulling excessive toner with every page printed. Since the process used in the PCU is write to no charge then the surface of the drum is not being fully charged. Could be the drum, the charge roller, the HVPS or contacts for the charge roller.

          One other question.Does the yellow shading only occur when copying?If so the problem is in the scanner.
