ERROR CODE
E-3
E012
Main cause The drum motor (M3, M4, M5, M6) is faulty. The drum motor drive system
has an excess load. The DC controller PCB is faulty.
Condition of
detection
XX=01: Y, XX=02: M, XX=03: C, XX=04: Bk (XX indicates the develop-
ing assembly color)
XX01 The target speed cannot be attained even when the frequency of the
motor drive pulse is increased to the upper limit.
XX02 The target speed cannot be attained even when the frequency of the
motor drive pulse is decreased to the lower limit.
XX03 The encoder signal from the motor is not generated for the follow-
ing period of time:
standard: 3.69 msec, 1/2 speed: 7.38 msec, 1/4 speed: 14.75 msec
XX04 The motor rotates in the direction opposite the desired direction.
XX05 The spatial displacement is not corrected even when the frequency
of the motor drive pulse is varied.
XX06 The target speed cannot be attained even when the frequency of the
motor drive pulse is varied.
XX07 Not used.
XX08 Not used.
XX09 An error has occurred in the communication with the DC controller
PCB.
E013
Main cause The waste toner feedscrew has locked. The waste toner feed motor is faulty.
The transfer high-voltage PCB is faulty. The serial driver PCB is faulty. The
DC controller PCB is faulty.
Condition of
detection
0001 The waste toner motor has locked and, as a result, an over-current
has flowed into the motor control circuit.
0002 An open circuit has occurred in the waste toner motor.
