- Code: 203
- Description: Polygon mirror motor error 2: Timeout at OFF
The polygon mirror motor did not leave "Ready" within 3 sec. after the motor was switched off. (The XSCRDY signal did not go HIGH (inactive) within 3 sec.) - Causes:
• The polygon mirror motor PCB connector is loose, broken, or defective
• Polygon mirror motor PCB defective
• Polygon mirror motor defective
• IPU defective
- Code: 204
- Description: Polygon mirror motor error 3: XSCRDY signal error
The polygon mirror motor "Ready" signal went inactive (HIGH) while the motor was operating at normal speed, even though the motor was neither switched off nor was there a request for a change in speed. - Causes: • Electrical oise interference on the line with the motor signals
• Polygon mirror motor PCB connector loose, broken, defective
• Polygon mirror motor PCB defective
• Polygon mirror motor defective
- Code: 205
- Description: Polygon mirror motor error 4: Unstable timeout
The "Ready" signal (XSCRDY) was detected as unstable for more than 20 sec. while the polygon mirror motor was operating at normal speed. - Causes: • Electrical noise on the line with the motor signals
• Polygon mirror motor PCB connector loose, broken, defective
• Polygon mirror motor PCB defective
• IPU defective
- Code: 220
- Description: Laser synchronization detection error
The 1st laser synchronization detection unit could not detect the line synchronization signal (DETP0) within 500 ms while the polygon mirror motor was operating at normal speed. Note: The unit polls for the signal every 50 ms. This SC is issued after the 10th attempt fails to detect the signal. - Causes: • Laser synchronization board connector loose, broken, defective
• Laser synchronization detection board is not installed correctly (out of alignment)
• Laser synchronization board defective • IPU defective
- Code: 300
- Description: Charge corona output error
The feedback voltage from the charge corona unit is detected too high 9 times - Causes: • Charge corona power pack defective
• Charge corona harness disconnected
• Poor charge corona unit connection
- Code: 303
- Description: Charge corona grid leak
When the high voltage is output to the corona grid, feedback voltage exceeds the prescribed value 9 times. - Causes: • Charge corona power pack defective
• Charge corona harness disconnected • Poor charge corona unit connection
