    did u check if this issue is before transfer or after transfer

    Transfer Bias/Separation Static Eliminator Bias Control

    DC bias is applied to the transfer roller and static eliminator


    BIAS
    =====DC Controller PCB

    Primary Charging Bias Control

    The machine is directly charged by the charging roller. DC bias and AC bias that stabilized
    the charge is applied to the primary charging roller.

    Constant voltage control of DC bias and AC bias

    The DC bias and AC bias control circuits on the DC controller PCB control the DC bias and
    AC bias applied to the primary charging roller to keep their voltage at the fixed level.
    Developing Bias Control
    The DC bias and AC bias are applied to the developing cylinder.

    Primary Charging

    Charging method Primary charging roller
    AC bias constant voltage control: approx. 550 to 2600Vp-p
    DC bias constant voltage control: approx. -400 to -800V
    DC bias switch control (variable according to environment
    sensor detection)

    Developing

    Developing Method= Dry one-component jumping development
    AC bias constant voltage control: approx. 800Vp-p
    DC bias control: approx. -300 to -700V
    DC bias switch control (variable according to density
    setting, environment sensor detection)

    Re: Canon IR 2530 curvy line backgrounds

    Does remind me of a main charge issue on a different brand.
    not the same but similar, have you fixed this?
    If so post the solution

    on my experience it would have happened when we are using not genuine toner the possible cause the old toner and new toner mixing inside the developer, you only have to do is remove the toner and clean the developer unit and clean the mag roller. and try to initiallize it the new toner going to the developer.....and try to print more copy....

    Yes. I like this solution too.

    Even if it is an OEM toner cartridge, I've had endusers dump some other brand toner into the cartridge. Bring your vacuum and a know new, un-tampered with OEM toner cartridge. Vacuum out your new developing unit and re-fill the developing unit from that new cartridge. =^..^=

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.

    Thanks all for your responses. I was only able to get access to the printer Friday. Now the patterns appear on the top quater only. And you can see it on the drum and developer unit.

    Does that mean that you won 't be attempting any of the suggested solutions? =^..^=

    There is a pattern there,
    I would think of the charge (primary) roller worn or contaminated.
    try another drum unit to make a test.
