    Checking the LED Activation for the Potential Measurement Circuit
    LED1 remains on at all times as long as the copier is supplied with power, indicating that the
    potential sensor is operating normally.
    If it is not in a normal way, suspect that the 24 V-F power is
    not supplied or the potential measurement unit is faulty.

    Re: Photosensitive Drums life of CLC copiers

    Hi to all. Here are the last news:

    Checking the LED Activation for the Potential Measurement Circuit
    Yes, the red LED is always on.
    I cleaned potential sensor unit, but I solved the problem of E061-070 only after applying the advise of DanielCanon:

    for clear code E061-0070 execute:
    *28*
    copier
    adjust
    laser
    p3-vff-4 = 0
    Now the values DPOT are:
    V00-500---------------430 to 570 ---> 443
    V00-700---------------600 to 800 ---> 633
    VFF-500---------------50 to 150 ---> 81
    VFF-700---------------100 to 200 ---> 128
    The drum is this colour:

    photo made without flash and low office illumination
    I think is dark green, but now it works!

    Now the problem is Magenta Colour --> E020-0100
    Some weeks ago the copier gave errors of dirty sensors (before E061-070). So I cleaned all sensors of developer units then I made STIR-4 and only INIT-M. Now the REF-M = 1.
    The machine makes copies with single colour black, yellow, cyan, but not magenta.

    Here are all the DENS displayed:

    What can I do now?

    two things
    1- ATR cable check magenta sensor which can be broken.
    2- ATR magenta sensor exchange.

    if your cables are nice and tight on the front of the developer unit then I would pull it back out and make sure all of the HVT contacts are tight at the rear of the unit and coming across the the bottom at the front. They are attached by screws and can work their way loose causing odd issues. You might want to make sure that you also do not have a build up toner/starter on the rack assembly where the metal tab is that supplies the HVT connection to the developer units. You can access these with the drum and developer units out.

    The other thing that is sticking in my mind is that your developer unit might not be camming up into place all the way during operation or when running the INIT-M. A lot of times the hopper sags putting extra pressure on your K & M developer units which in turn can cause false readings when running an INIT.
    Accidents don't just happen. They must be carelessly planned.

    The cable isn't broken but the assembly must have some problems. I tested it in one of my CLC 1150 and it gives the same error code.
    Instead the assembly of 1150 inserted in 1130 works well.
    So for now 1130 is ok!
    I'll make other copies and prints however.

    Thanks also for this advertise; I'll do further check-ups, cause I have other problems also with CLC 1150. I will post soon

    Thanks to all for support. Barbara

    you are welcome. These machines can be head scratchers so dont be afraid to ask before doing something. If you can get your hands on a developer unit for the M it might be worth it, or just clean it all out and add new developer to it.

    Re: Photosensitive Drums life of CLC copiers

    u should only do the STIR & INIT when replacing(starter)

    i always did a FULL all Starter change when needed on Volume use

    and replaced all stater on a Drum change-
    this will prevent a lot of E020 errors/

    tech tip on erroneous E020/Dirty grid plate->>>>> in back of printer / facing the back > remove back cover & in upper right side corner> on the FM2 Exhaust fan >remove that fan ozone FILTER & throw in garbage> do not replace u


    and make sure to replace or clean the filter of the FM3 Primary charging assembly fan/ rear upper left corner
