    Are you sure this is the correct error code, Can't see E302-0003 listed ?

    However I would start by updating the system software,

    E302-0003-04 Error in paper front white shading
    Detection Description The paper front white shading value gradually became out of the specified range.
    Remedy [Related parts]
    - Harness between the Reader Scanner Unit (J101) and the Reader Controller PCB (J105)

    - Reader Controller PCB
    [Remedy]
    1. Clean the LED, mirror, and Stream Reading Glass of Scanner Unit.
    2. Check/replace the related harness/cable, connector and parts.
    [Reference] Before replacing the Reader Controller PCB, back up the service mode data (approx.

    Re: Canon IR adv C5535i E302-0003

    was an odd fault
    when copying colour or b/w on the glass worked fine
    when copying b/w thru adf worked fine

    Error only occurred when copying colour thru the adf

    Turned out to be a staple on the Reader Controller PCB

    Very common to see this. Clean the optics, mirrors, scratch the glue off the bottom mirror to slide out for cleaning. Then do white level calibration x4

    Thanks Venom
    Your advise helped turned out to be the optics unit faulty
    possibly caused by the staple on the controller pba
    stripped and cleaned optics and adjusted still same
    replaced the optics did adjustment and now working fine

    If it works fine off the glass but only does it when scanning from the ADF then most likely its the scan flat harness. FM1-T689-000.

    I think it is a minor miracle sometimes how a staples, etc can get into the machine; I once had one of those huge paper clips on a pcb in the adf. No clue how it made it's way there.
