    MX-2610 E7-A0

    I have a Sharp MX-2610 that has intermittent E7-A0 codes. I've already replaced the LSU with driver PWB and just replaced the LSU motherboard from a spare MX-3110 (same Part#). Within 5 minutes it popped another E7-A0. I can reset using sim 14 and it may take a few days of several weeks for it to come up again, its occurred 7 times between 4/2017 and 9/2017. Other than the harness, any suggestions?

    I apologize if I didn't make it clear in my initial post but the code is:

    E7-A0 LSU LD PWB EEPROM read/write
    error (K)
    Trouble content Write error in the EEPROM write sequence
    Detail PCU
    Cause LD PWB EEPROM trouble.
    LSU mother PWB trouble.
    Connector/harness trouble between the LD PWB and
    the LSU mother PWB.
    Connector/harness trouble between the PCU PWB
    and the LSU mother PWB.
    Check & Remedy Check the LSU, and replace if necessary.
    Check the LSU mother PWB, and replace if
    necessary.
    Check the connector/harness between the LD PWB
    and the LSU mother PWB, and replace if necessary.
    Check the connector/harness between the PCU PWB
    and the LSU mother PWB, and replace if necessary.
    Replace the LSU.

    Print out the 22-6 and look at the soft switches. I have seen board replacement set all the soft switches to 1.
    This usually happens with Frontier scanner boards....
