    4/4e series paper size on tray

    Hello,

    I found the bizhub 4/4e series have common issue below:
    The tray 1 often have auto paper size detection error, place A4-> display 8 1/2" x 11" , place A3 -> display 11" x 17".
    I tried to test the paper size detection sensors by exchanging them with tray 2 however the same result occurred.
    Have any idea about this?

    This is a know issue, the wire on the connector breaks, you need to replace the small loom.

    Could it also be the marketing area is not set correctly?
    We know a thing or two because we've seen a thing or two.

    or somebody not pulling the connector properly .. never remove a connector by grabbing just the wire harness

    I checked the connectors and 2 wires loosened,
    it seems nothing happened on 8 series.

    Probably because most users use tray 1 more often.
    I have only 1 case and it happened because user do very much id card copy but they copy one side then put back paper to tray 1 and copy 2nd id card side
    Too much open-close tray will over time damage this wires.
