    What is the condition of your ITB unit? I can see colours bleeding over the black prints. Have you done calibration with these prints to try to get the machine to correct the undertaking/grainy image
    If it works, don't touch it.

    Re: mpc 4502 black color quality

    you can set the machine to do single color and do a 2 inch sky shot and see the fill for cyan or yellow or magenta

    How to enable single color mode - use SP5-618 change to 0

    Fixing copiers is not a matter of believing the parts counter value is just a guideline, not a guaranteed lifespan.
    Please start you post with brand, model, problem.

    i agree that the original sleeves suck but after changing them out these models hold up..

    I agree with that statement but for less than 50% of its life? No.My mind goes there difficult for Ricoh parts.99.999% cover their lifetime.I can accept 10 to 20 %

    well if premature failure is a problem... then look at the environment - users - supplies - paper

    does the machine sit unused for a long time? ( staying ready wears down fuser & drums)

    paper weight can make a BIG diff in life of parts

    we all know cheap toner can destroy a unit.

    and lastly.. are they gentle on the machine or rough?

    yields aren't really something that can be depended to go full life... esp with all other factors involved
