    c-4512, c-4511 error codes on KM c6000L

    These two error codes appeared after chart setting of the two side printing. Service manual says to check input for the motor and tilt correction home position sensor but I really have no clue what the codes are. I'd really appreciate any help if any of you guys ever has similar problems.
    And the aditional problem is i definitely won't find new writing unit to replace it

    The two codes: C4511 & C4512, are errors resulting from the yellow laser being unable to complete it's adjustment.

    It's possible that the inside of the yellow laser is dirty, or you may need to replace the yellow laser unit. It's not quite as easy as it sounds. =^..^=
    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.
    5) You are the person onsite. Only you can make observations.

    I'll try that but a little bit uncertain about what to clean it with, will rubbing alcohol will get the job done? One more thing, tilt correction home sensor and/or the motor for Y and M write units do they have any input code to check them from service menu. Couldn't find anything in the service guide i have at least

    I would use a microfiber cloth and non-ammonia glass cleaner. Alcohol is OK too.

    You may check "Color Registration Auto Adjustment" for inconsistent values. =^..^=

    Color reg auto adj. In fact returning me c-4512/11 errors. Although I'm not really sure what's the value range for it to look at the old data.
    One more thing i'd like to make sure about is how chart adjustment for duplex could possibly cause it.

    When executing Chart Adjustment, Mag. Skew Adjustment is performed automatically (to compensate face-back misregistration due to image skew). When Mag. Skew Adjustment value changes Color Registration Auto Adjustment is performed automatically, and the error pops-up. Perform Both Side Adj. instead.

    Both sides adj. giving the same c4512 error.

    Try swapping the yellow laser unit "LPH" with the Cyan and see if the error moves with it.

    I had a C7000 once blow 2 of 4 units due to a possible power surge.
    The machine auto tests yellow first and then moves down the list from there. In my case it was throwing a yellow code c-4511. Replaced yellow just to get a magenta code next c-4512.

    I am currently parting out a C6000 if you end up needing a LPH unit. Just PM me if interested.

    Keep in mind that the black laser is unique, not the same as the color lasers. =^..^=

    A bit offtopic but... nowadays it would be interesting sending parts from USA to Russia
