Description: The laser scanner motor (M15) is faulty. The wiring is faulty (short circuit, open circuit). The DC controller PCB is faulty
• After the laser scanner motor drive signal has been generated, the motor ready signal (LMRDY*) does not arrive for 15 secs or more. (stop - full speed, half-speed - full speed) • During the period of 'full speed ® half speed', the motor ready signal does not arrive for 60 secs or more after the speed change signal has been generated. • During the period of 'full speed rotation', the motor ready signal is not detected 50 times or more (t intervals of 100 msec).
Code: E121-0001
Description: The controller cooling fan (FM4) is faulty. The wiring is faulty (short circuit, open circuit). The DC controller PCB is faulty.
Although the controller cooling fan (FM4) is being driven, the clock signal (FM4CLK) does not arrive for 5 secs or more.
Code: E196
Description: The EEPROM on the DC controller PCB is faulty. The location of the EEPROM is wrong. The DC controller PCB is faulty.
1abb: When data is written to the EEPROM, the data written and the data read do not match. 2abb: When the ID read into the EEPROM and the ID into the ROM are compared, a mismatch is found. 3abb: When ID in the EEPROM and the ID in the ROM are compared after the main power switch is turned on, a mismatch is found. a: chip Nos. 0 through 5 (0: IC104, 1: IC105, 2: IC109, 3: IC110, 4: IC127, 5: IC130) bb: chip faulty address (bit)
