    ir2004N without counter display

    Good day guys,


    I have a iR2004N problem started with main controller P.C.B the network port is not working.

    Hence I have order a new main controller thru Canon and replaced it to this machine well everything is back working fine it can print/copy & scan. The only problem now when I press the counter check button on the panel to check the counter display was disappear.

    Do you guys encounter this problem before ? Where do I set it back ?

    How to enter service mode for this model ? I don't have the service manual to refer to. Thank you

    so you swapped main board Without having a service manual? thats why your counter is missing. you didn't init the board properly

    I believe you get into service mode the usual way, if that doesn't work try hitting the 2 and 8 keys consecutively, not simultaneously. Did you have any secondary pcbs on the main controller or memory to swap over? Perhaps flashing the firmware may help.

    First re-check your connections on pcb.

    (one press on each key)

    or
