CHAPTER 5 SELF DIAGNOSIS
5-7
E240
Main Cause
The main controller PCB. The DC controller PCB is faulty.
Mode of
Detection
0000 An error has occurred in the communication between the main
controller PCB and the CPU of the DC controller PCB.
E243
Main Cause
The control panel CPU PCB is faulty. The main controller PCB is faulty.
Mode of
Detection
0000 An error has occurred in communication between the CPU of the
control panel CPU PCB and the main controller PCB.
E248
Main Cause
The EEPROM on the reader controller PCB is faulty. The reader controller
PCB is faulty.
Mode of
Detection
0001 The ID read into the EEPROM when the main power switch has
been turned on and the ID in the ROM do not match.
0002 When data is written into EEPROM, the data written and the data
read do not match.
0003 When data is written, the ID in the EEPROM and the ID in the
ROM are found not to match.
E302
Main Cause
The CCD/AP PCB is faulty. The wiring is faulty (short circuit, open cir-
cuit). The reader controller PCB is faulty.
Mode of
Detection
0001 During shading, the reader controller PCB does not end shading in
1 sec.
0002 In stream reading, the edge white accumulation (processing) does
not end after a period of 10 secs.
