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.
Replace the sub hopper toner sensor. Connect the connector. Replace
the detection PCB.
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.
Replace the hopper motor. Replace the bottle motor. Replace the DC
controller PCB.
E032 The NE controller counter malfunctions.
0001 An open circuit is detected for the count pulse signal. Turn off the main power, and check the cable for an open circuit; then,
turn the main power back on.
E064 The voltage of the power supply is faulty (high-voltage error).
0001 The value read from the EEPORM is outside a specific range. Turn off and then back on the main power. Replace the EEPROM.
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.)
Replace the high-voltage power supply. Replace the DC controller
PCB.
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.)
Replace the high-voltage power supply. Replace the DC controller
PCB.
0004 While output is being generated, the AD value of the transfer output current is 205
(DEC) or more for 100 msec 2 times in sequence. (However, after output, it is not
detected for 100 msec.)
Replace the high-voltage power supply. Replace the controller PCB.
0005 While output is being generated, the AD value of the transfer output voltage is 0
(DEC) for 100 msec 2 times in sequence. (However, after output, it is not detected
for 100 msec.)
Replace the high-voltage power supply. Replace the DC controller
PCB.
E100 The BD interval is outside a specific range.
0001 After the machine has become ready for image formation (i.e., the scanner motor
is ready for operation, and the laser has been turned on), an error has occurred 50
times or more (BD error).
Replace the laser unit. Replace the DC controller PCB. Check the
wiring.
E110 The scanner motor is faulty.
0001 The scanner motor speed lock signal does not indicate a locked state a specific
period of time after the scanner motor has been started.
Replace the laser unit. Replace the DC controller PCB. Check the
wiring.
0002 The speed lock signal indicates a deviation 10 times in sequence at intervals of 10
msec after the signal has indicated a locked state.
Replace the laser unit. Replace the DC controller PCB. Check the
wiring.
0003 With the image clock switched over, the scanner motor speed lock signal does not
indicate a locked state 6.5 sec after a switchover is made from low to normal speed
or 8 sec after a switchover is made from normal to low speed.
Replace the laser unit. Replace the DC controller PCB. Check the
wiring.
E191 There is an error in the communication with the high-voltage power supply.
0000 The data transmission/reception does not end normally 500 msec after the most
recent transmission/reception of data ended normally.
Replace the high-voltage power supply. Replace the DC controller
PCB.
E202 There is an error in the detection of the CIS home position.
0001 The attempt to detect the home position fails when the CIS is moved forward. Disconnect and then connect the harness connector. Replace the
following as necessary: scanner home position sensor, scanner motor,
reader controller PCB.
0002 The attempt to detect the home position fails when the CIS is moved back. Disconnect and then connect the harness connector. Replace the
following as necessary: scanner home position sensor, scanner motor,
reader controller PCB.
E225 The light intensity of the CIS is faulty.
0001 During shading operation, the intensity is below a specific level. Disconnect and then connect the flexible cable. Replace the following
as necessary: flexible cable, CIS, reader controller PCB.
0002 During DF stream reading, the sheet-to-sheet light intensity is faulty. Disconnect and then connect the flexible cable. Replace the following
as necessary: flexible cable, CIS, reader controller PCB.
E227 The reader unit power supply is faulty.
0001 At time of power-on, the 24-V port is off. Disconnect and then connect the power supply harness connector.
Replace the power supply.
0002 At the start of a job, the 24-V port is off. Disconnect and then connect the power supply harness connector.
Replace the power supply.
0003 At the end of a job, the 24-V port is off. Disconnect and then connect the power supply harness connector.
Replace the power supply.
0004 When a load is being driven, the 24-V port is off. Disconnect and then connect the power supply harness. Replace the
power supply.
E248 The backup memory is faulty.
0000 [Cause] A check error has occurred on the backup SRAM board.
[Location] bottom ROM
[Timing of Detection] once when the boot ROM is started up
1. Check the presence/absence of a backup SRAM PCB.
2. Disconnect and then connect the backup SRAM PCB.
3. Replace the backup SRAM PCB with a new one.
0001 An error has occurred at power-on. Replace the reader controller PCB.
0002 An error has occurred during a write operation. Replace the reader controller PCB.
0003 An error has occurred during a read operation following a write operation. Replace the reader controller PCB.
E261 The zero-cross signal is faulty.
0000 When the relay is on, the zero-cross signal is not detected for 500 msec or more. Replace the AC driver PCB. Replace the DC controller PCB.
E315 There is an error in image data.
0007 There is an error in JBIG encoding. Turn off and then back on the power.
000d There is an error in JBIG decoding. Turn off and then back on the power.
E602 There is an error on the hard disk.
