developing assembly toner sensor does not
detect the presence of toner.
The developing assembly connector is
E024- disconnected.
0000 The connection detection signal is absent
continuously for 100 msec.
The hopper motor or the bottle motor is
faulty.
E025-
The sub hopper toner sensor connection

detection signal is absent for 100 msec 10
times in sequence.
Code
The hopper motor or the bottle motor is faulty.
While the hopper motor is rotating, the motor error
E025- lock signal is detected continuously 4 times every 56
0001 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.
The voltage of the power supply is faulty (high-
E064- voltage error).
0001 The value read from the EEPORM is outside a
specific range.
The voltage of the power supply is faulty (high-
voltage error).
E064- While output is being generated, the AD value of the
0002 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.)
The voltage of the power supply is faulty (high-
voltage error).
E064- While output is being generated, the AD value of the
developing DC voltage is 224 (DEC) or more for 10
0003
msec 2 times in sequence. (However, after output, it
is not detected for 100 msec.)
The voltage of the power supply is faulty (high-
voltage error).
E064-
While output is being generated, the AD value of the
0004
transfer output current is 205 (DEC) or more for 100
msec 2 times in sequence. (However, after output, it

Description
Replace the developing assembly toner
sensor. Connect the connector. Replace
the DC controller PCB.
Remedy
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.
Replace the high-voltage power
supply. Replace the controller
PCB.
