Code :

Code: 195
Description: Serial Number Error The serial number stored in the memory (EGB) is not correct.
Causes: • EEPROM defective • EGB replaced without original EEPROM
Remedy: 1. Check the serial number. 2. If the stored serial number is incorrect, contact your supervisor.

Code: 202
Description: Polygon motor error 1: ON timeout The polygon mirror motor does not reach the targeted operating speed within 5 sec. after turning on or changing speed.
Causes: • Polygon motor/driver board harness loose or disconnected • Polygon motor/driver board defective • Laser optics unit defective • IPU (EGB) defective
Remedy: 1. Replace the interface harness of the laser optics unit. 2. Replace the laser optics unit. 3. Replace the EGB (Engine Board).

Code: 203
Description: Polygon motor error 2: OFF timeout The polygon mirror motor does not leave the READY status within 3 sec. after the polygon motor switched off.
Causes: • Polygon motor/driver board harness loose or disconnected • Polygon motor/driver board defective • Laser optics unit defective • IPU (EGB) defective
Remedy: 1. Replace the interface harness of the laser optics unit. 2. Replace the laser optics unit. 3. Replace the EGB (Engine Board).

Code: 204
Description: Polygon motor error 3: XSCRDY signal error The SCRDY_N signal remains HIGH for 200 ms while the LD unit is firing.
Causes: • Polygon motor/driver board harness loose or disconnected • Polygon motor/driver board defective • Laser optics unit defective • IPU (EGB) defective
Remedy: 1. Replace the interface harness of the laser optics unit. 2. Replace the laser optics unit. 3. Replace the EGB (Engine Board).

Code: 220
Description: Laser Synchronizing Detection Error: [K]/[Y] The laser synchronizing detection signal for LDB [K]/[Y] is not output after the LDB unit has turned on while the polygon motor is rotating normally.
Causes: • Disconnected cable from the laser synchronizing detection unit or defective connection • Defective laser synchronizing detector • Defective LDB • Defective EGB
Remedy: 1. Check the connectors. 2. Replace the laser optics unit. 3. Replace the EGB.

Code: 222
Description: Laser Synchronizing Detection Error: [M]/[C] The laser synchronizing detection signal for LDB [M]/[C] is not output after the LDB unit has turned on while the polygon motor is rotating normally.
Causes: • Disconnected cable from the laser synchronizing detection unit or defective connection • Defective laser synchronizing detector • Defective LDB • Defective EGB
Remedy: 1. Check the connectors. 2. Replace the laser optics unit. 3. Replace the EGB.

Code: 300
Description: High voltage power output error The measured voltage is not correct when the EGB measures each charge output (charge, development, image transfer belt unit, and transfer unit).
Causes: • Disconnected or defective high voltage harness • Defective high voltage power supply • Defective EGB
Remedy: 1. Check or replace the harnesses. 2. Replace the high voltage power supply board 3. Replace the EGB.
