    Re: bizub c258 Image Quality Yellow

    Hi man,

    first use original toners, then check consumable status: drum, developer, transfer belt, transfer roller.

    Then if the problem will be again empty yellow parts on printed paper, evaluate to change or refurbishind yellow developer.

    Cheers

    Exactly! Should be even in Forum rules.

    No Error Codes. Sample is SEF. Now getting back to office trying to check - "modify" distance between drum and dev Unit.

    Try same test print on A3 paper and post again.
    Did somebody before "modify" DR/DV distance?

    I know this is ancient thread but if this A4 size then it looks like what happened when I inserted a black drum in the yellow drum without changing the plastic part between them.
    Are you sure you are sold a Y drum and not a chipped K but without that special plastic part that only the CMY drums have?
