    Exclamation MPC 2050 Original size not recognized from glass

    Hi guys,

    we're having such a problem on original paper size recognition onto 2 MPC2050.
    The problem looks solved by cleaning CCD but after few hours it came back.
    We changed both optical sensors and re-cleaned CDD with no issue.

    Any clue or advice.

    Thanks

    Vincenzo

    May have something to do with the adf position sensor.
    Don't take that toner with me!

    Thanks in advance.

    We checked ADF position and is ok.
    Then we checked sp-4-301 and is looking strange...value is always "00001" even without paper on glass.
    But sensors are new. Any clue?

    I am not very familiar with this particular model, but normally on-the-glass original size is detected by the original length and original width sensors that are under the glass. There should be 3 length sensors and 2 width sensors. The CCD has nothing to do with it. As previously mentioned, the sensors are turned on by the ADF platen cover sensor. (open/closed). If your reading 00001 with nothing on the glass you have a problem with width sensor #2. Check your connectors or replace it.

    I just picked up an MP C3500 to refurbish, and it had the exact same problem....updating firmware solved it.

    That's good info. I have several MPC3500's in the field, but I've not run into that yet.
