0001 The laser scanner unit cooling fan has a fault.
After the laser scanner unit cooling fan has gone on, the fan stop signal is
detected for 5 sec
or more. Disconnect and then connect J503 of the DC controller PCB.
Replace the laser scanner unit
cooling fan. Replace the DC controller PCB.
0002 The reader heat discharge fan 1 has a fault.
After the reader heat discharge fan 1 has gone on, the fan stop signal is
detected for 5 sec or
more. Connect and then disconnect J512 of the DC controller PCB.
Replace the reader heat
discharge fan 1. Replace the DC controller PCB.
0003 The reader heat discharge fan 2 has a fault.
After the reader heat discharge fan 2 has gone on, the fan stop signal is
detected for 5 sec or
more. Disconnect and then connect J521 of the DC controller PCB.
Replace the reader heat
discharge fan 2. Replace the DC controller PCB.
E193 Video PCB initialization error
0001 Initialization of the video PCB has failed. Unplug and plug the connector to the video PCB, unplug and
plug the connectors of the cable between the DC controller
and the main controller, replace the video PCB, or replace the
DC controller PCB.
E197 The laser scanner motor communication has a fault.
0000 The communication with the laser control IC is not normal. Replace the laser scanner unit. Replace the video PCB.
E202 The scanner HP detection mechanism has a fault.
0001 While HP positioning is under way, the forward trip fails. Disconnect and then connect the connector of the scanner HP
sensor. Replace the scanner
HP sensor. Replace the scanner motor. Replace the reader
controller PCB.
0002 While HP positioning is under way, the reverse trip fails.
E225 The intensity of the scanning lamp is inadequate. (The lamp is exhausted.)
0001 At time of shading, the intensity of light is below the standard level. Disconnect and then connect the connector of the scanning
lamp. Replace the scanning
lamp. Replace the inverter PCB. Replace the reader controller
PCB.
** 0002 In ADF mode, the intensity of light is below the standard level between sheets.
E227 The reader unit power supply (24 V) has a fault.
0001 At power-on, the 24V port is off. Disconnect and then connect the reader power supply
connector. Replace the power supply.
0002 At the start of a job, the 24V port is off.
0003 At the end of a job, the 24V port is off.
0004 While a load is driven, the 24V port is off.
E240 ** A fault exists in the communication between the main controller and the DC controller.
0000 A fault has occurred in the communication between the CPUs of the main
controller and the
DC controller. Disconnect and then connect the connector. Replace the DC
controller PCB. Replace the
main controller PCB.
E248 A fault exists in the following: main controller SRAM, reader controller EEPROM.
0000 At start-up, an SRAM check error has occurred. Replace the main controller PCB.
0001 An error has occurred at time of power-on (EEPROM). Replace the reader controller PCB.
0002 An error has occurred during write operation (EEPROM).
0003 A read error has occurred after write operation (EEPROM).
E251 The inverter cooling fan rotation is faulty.
0000 After the inverter cooling fan has gone on, the fan stop signal is detected for 5
sec or more. Disconnect and then connect J1110 of the reader controller
PCB. Replace the inverter cooling
fan. Replace the reader controller PCB.
E302 Shading operation is faulty.
0000 In the course of shading operation, the processing doses not end within the
reader
controller. Disconnect and then
connect J1107 and J1108 of the reader controller PCB.
Replace
the reader controller PCB.
E315 The image data codec has a fault.
0007 A JBIG encoder error has occurred. Replace the main controller PCB.
000d A JBIG decoding error has occurred. Replace the DDR-SDRAM. Replace the HDD. Replace the
main controller PCB.
000e An error has occurred in the course of software decoding.
0100 An overrun error has occurred. Replace the main controller PCB.
0200 the open I/F relay PCB has detected an error (no recovery after a retry). Replace the open I/F relay PCB (relay PCB between the main
controller and PS
controller).
0300 Cubic time-out Turn off and then back on he power. Replace the main
controller PCB.
0400 Shift Device A time-out
0401 Shift Device B time-out
E351 An error has occurred in the main controller communication.
0000 At start-up, a main controller communication error has occurred. Replace the main controller PCB.
E400 ** An ADF communication error has occurred.
0001 A check sum error has occurred. Disconnect and then connect the connector. Replace the
reader controller PCB. Replace the
ADF controller PCB.
0002 A reception status error has occurred.
0003 A reception interrupt error has occurred.
E402 * The ADF belt motor rotation is faulty.
