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.
0001 [Cause] An HDD detection error has occurred.
The HDD cannot be detected. The HDD does not
become ready. The HDD returns an error.
[Detection] while boot ROM is in session
BARSAC startup, mounting
(usrIde)
[Timing of Detection] once at startup
See the details under 602.
0002 [Cause] There is no startup file. The program for
the main CPU does not exist on the HDD or in
BOOTDEV/BOOT, and so on.
[Detection] while boot ROM is in use
at time of system file loading (usrIde)
[Timing of Detection] once at startup
See the details under 602.
