Description: Scanner communication error: Back side The read operation of the ASIC registry in the CIS returned an unexpected value.
Causes: • Harness between the ADF PCB and CIS is loose, broken, defective • ASIC in CIS is defective • FROM in CIS is defective
Remedy: • Inspect and reset power harness, signal harness. • Replace CIS signal harness • Replace CIS • Replace ADF main board.
Code: SC195-00
Description: Machine serial number error The number registered for the machine serial number does not match.
Causes: • The correct 11-digit serial number must be registered in the main machine.
Remedy: • Confirm the correct serial number. • The correct serial number must be entered with SP5811-001.
Code: SC202-00
Description: Polygon mirror motor error 1: Timeout at ON The polygon mirror motor unit did not enter "Ready" status within 20 sec. after the motor was turned on
Causes: • The polygon mirror motor PCB connector is loose, broken, or defective • Polygon mirror motor PCB defective • Polygon mirror motor defective • BICU defective
Remedy: • Inspect polygon mirror motor harness, replace if damaged • Replace polygon mirror motor • Replace BICU
Code: SC203-00
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
Remedy: • Inspect polygon mirror motor harness, replace if damaged • Replace polygon mirror motor
Code: SC204-00
Description: Polygon mirror motor error 3: XSCRDY signal error The polygon mirror motor "Ready" signal goes inactive (HIGH) while images are being produced or the synchronization signal is being output.
Causes: • Polygon mirror motor PCB connector loose, broken, defective • Polygon mirror motor PCB defective • Polygon mirror motor defective
Remedy: • Inspect motor PCB connection • Replace polygon mirror motor
Code: SC220-00
Description: Laser synchronization detection error The 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
