    Ricoh mpc3003 pale magenta

    Hi All,
    Problem with Magenta Color. Magenta Color seems to be pale on printout, new OEM opc drum, developer etc. ID Sensors cleaned, laser unit cleaned.
    Attached is a copy of color pattern, if you take a close look at the color pattern, by the left Magenta color looks pale, right side comes out full. Does any one knows what could be wrong???.
    Thanks All.

    In the ITB Unit as shown?
    Maybe that's the problem, the roller that adjusts the transfer part to the Magenta Unit, does not fit correctly.
    Or you may need to review the cleaning to the Laser Unit.
    ​Apologies for my English, it's not my mother tongue and I'm helping the translator.
    ALL WILL BE WELL

    I'll inspect the ITB and Laser Unit when I get there. I believe the problem might be around the two mentioned.

    Certainly looks like a dirty magenta LD shield. Or something is wrong in the M pcdu.

    Looks to me like either the magenta transfer roller in the ITB assembly is sticking on one end, there is uneven distribution of developer across the development roller or a bad or missing end plate on the PCDU causing a misalignment between the drum and both the transfer roller and development unit.

    You say you replaced a new OPC drum, do you mean you fitted a genuine Ricoh PCU ? or just the OPC drum cylinder ?

    He said OEM which we both know does not mean Genuine Ricoh. Same for developer and toner. OEM just means the same recipe but not the same quality of ingredients, production or testing.

    Some users believe they are replacing an OEM DRUM when as we know Ricoh only supply the complete PCU.
