Code Cause
E025 The hopper motor or the bottle motor is faulty.
0000 The sub hopper toner sensor
connection detection signal is
absent for 100 msec 10 times in
sequence.
0001 While the hopper motor is
rotating, the motor error lock
signal is detected continuously 4
times every 56 msec. Or, while
the bottle motor is rotating, the
motor error lock signal is
detected 22 times in sequence
every 10 msec.
E032 The NE controller counter malfunctions.
0001 An open circuit is detected for
the count pulse signal.
E064 The voltage of the power supply is faulty (high-voltage error).
0001 The value read from the
EEPORM is outside a specific
range.
0002 While output is being generated,
the AD value of the primary DC
voltage is 230 (DEC) or more for
100 msec 2 times in sequence.
(However, after output, it is not
detected for 100 msec.)
0003 While output is being generated,
the AD value of the developing
DC voltage is 224 (DEC) or
more for 10 msec 2 times in
sequence. (However, after
output, it is not detected for 100
msec.)
Remedy
Replace the sub hopper toner
sensor. Connect the connector.
Replace the detection PCB.
Replace the hopper motor. Replace
the bottle motor. Replace the DC
controller PCB.
Turn off the main power, and check
the cable for an open circuit; then,
turn the main power back on.
Turn off and then back on the main
power. Replace the EEPROM.
Replace the high-voltage power
supply. Replace the DC controller
PCB.
Replace the high-voltage power
supply. Replace the DC controller
PCB.
