    The dev roller is probably fully coated black.

    - I know what I need to know as I need to know it, but knowing is not enough I must understand what I know.

    Hi,
    The development roller is not coated black. Even this is not over toning problem.
    The problem is appearing after 2 to 3 days & then after servicing its working fine.
    Please let me know the solution.
    With best regards.

    Are you using OEM toner and the correct developer? B296 9640?

    Computers are serious tools, Michael!

    2. Make the following SP mode changes:
    - SP2201-01 (Development Bias): From 560 to 660
    - SP2201-02 (Development Bias for ID sensor pattern): From 400 to 500 "

    1. take off the toner bottle from the machine
    2. print/copy while appears the "toner empty"
    3. clean the developer roller, clean the waste toner unit, toner bottle unit.
    4. change the sp modification
    5. check the sp 2.001 (charge voltage) set the default 1.500 V !!!

    Re: Ricoh MP4000B

    Define "servicing the machine", as in all service consumables replaced, or a "open,vaccum out and clean" service ?

    Make the following SP mode changes:
    - SP2201-01 (Development Bias): From 560 to 660
    - SP2201-02 (Development Bias for ID sensor pattern): From 400 to 500 "
    Are these not the changes that were suggested, before they decided to modify the developer roller to a new coating version ? Is it the old version dev roller or the modfied one in the 'B' ?
