    if u are not a tech/ i would not reset it/ that is a heat protection code in fuser

    needs to be investigated first

    E004=• The triac has a short circuit.
    • The DC controller PCB is faulty

    • The triac is identified as having a short
    circuit

    1. When the diagnostic function has turned on, the copier can be reset by turning it off once.This, however, does not apply to E000, E001, E002, E003, or E004.
    This is to prevent the user from resetting the copier easily when the error is caused by an open circuit in the thermistor, otherwise overheating and damaging the fixing roller.
    Normally, the copier will automatically turn off in about 4 sec if it is turned on without clearing E000 through E004.

    To clear E000 through E004, operate as follows:
    1) Select ‘412’ under FUNCTION (clear E000–E004) in service mode.
    • The copier’s control panel indicates the respective error code.
    2) Press the Start key.
    3) The copier will automatically turn off, clearing the error.
    2. E202 may be checked using ‘108’ in service mode (error history indication).

    Starting Service Mode

    1) Press the User Mode key.
    2) Hold down the ‘2’ and ‘8’ keys on the keypad at the same time for 0.5 sec or more.
    3) Press the User Mode key once again.
    • The copier will indicate ‘[1]’ on its control panel as soon as it enters service mode.
    • The copier will end service mode in response to a press on the Reset key.
    Selecting Service Mode
    1) Select the mode you want for making checks or adjustments using the keypad.
    • The 10’s place will switch to indicate the input numeral.
    • The copier will start making copies in response to a press on the Start key using the settings
    that were effective immediately before the start of service mode.
    2) Press the AE key.
    • The copier will indicate a 3-digit number, and the 100’s place will start to flash and 10’ and
    1’s places will turn on.
    3) Select the mode you want to use for making checks or adjustments using the keypad.
    • The 10’s and 1’s places will serve to indicate the input numerals.
    • The copier will return to the condition in step 1) above in response to a press on the AE key.
    4) Press the Start key to execute the selected service mode.
    • The copier will return to the condition in step 3) in response to a press on the AE key while it is executing service mode.
    The copier’s service mode is divided into the following seven:


    No. Description
    [ 1 ]
    DISPLAY
    [ 2 ] I/O DISPLAY
    [ 3 ] ADJUST
    [ 4 ] FUNCTION
    [ 5 ] OPTION
    [ 6 ] COUNTER
    [ 7 ] APPLICATION
