Description: Machine serial number error Comparison of the product identification code in the machine serial number (11 digits).
Causes: The product identification code in the machine serial number (11 digits) does not match.
Remedy: Re-enter the machine serial number.
Code: SC202-00
Description: Polygon Motor: ON Timeout Error After the polygon motor turned on, or within the specified time (sec.) after the rpm’s changed, the motor did not enter READY status.
Causes: • The interface harness to the polygon motor driver damaged or not connected correctly. • Polygon motor or polygon motor driver defective • Polygon motor drive pulse cannot be output correctly. (Polygon controller) • XSCRDY signal observation failing (Polygon controller)
Remedy: 1. Turn the main power OFF/ON. 2. Reconnect the connectors between LD unit and IPU. 3. Check CN586 (a connector with 1 pin) for the polygon mirror motor from the PSU. 4. Replace the LD unit (Polygon mirror motor). 5. Replace the harness between the LD unit and IPU. 6. Replace the IPU. 7. Replace the PSU (or fuses on PSU).
Code: SC203-00
Description: Polygon Motor: OFF Timeout Error The XSCRDY signal (polygon ready) never becomes inactive (H) within 3 sec. after the polygon motor went OFF.
Causes: • The interface harness to the polygon motor driver damaged or not connected correctly. • Polygon motor or polygon motor driver defective • Polygon motor drive pulse cannot be output correctly. (Polygon controller) • XSCRDY signal observation failing (Polygon controller)
Remedy: 1. Turn the main power OFF/ON. 2. Reconnect the harness between LD unit and IPU. 3. Check CN586 (a connector with 1 pin) for the polygon mirror motor from the PSU. 4. Replace the LD unit (Polygon mirror motor). 5. Replace the harness between the LD unit and IPU. 6. Replace the IPU. 7. Replace the PSU (or fuses on PSU).
Code: SC204-00
Description: Polygon Motor: XSCRDY Signal Error During polygon motor rotation, the XSCRDY signal was inactive (H) for longer than one rotation of the polygon.
Causes: • The interface harness to the polygon motor driver damaged or not connected correctly. • Polygon motor or polygon motor driver defective
Remedy: 1. Turn the main power OFF/ON. 2. Reconnect the connectors between LD unit and IPU. 3. Check CN586 (a connector with 1 pin) for the polygon mirror motor from the PSU. 4. Replace the LD unit (Polygon mirror motor). 5. Replace the harness between the LD unit and IPU. 6. Replace the IPU. 7. Replace the PSU (or fuses on PSU).
Code: SC220-01, SC220-04
Description: SC220- 01 D Leading Edge: LD1 synchronization detection error: Bk SC220- 04 D Leading Edge: LD1 synchronization detection error: Ye The leading edge LD0 synchronization detection signal of the corresponding color was not output within the specified time (sec.) while the polygon mirror motor was operating at normal speed.
Causes: • The interface harness to the synchronization detection unit damaged or not connected correctly. • Synchronization detection board defective • Beam does not enter photo detector. • Abnormality around GAVD • LDB defective
Remedy: 1. Turn the main power OFF/ON. 2. Check for condensation on the LDB. 3. Reconnect the connectors between LDB (Synchronizing detector board) and IPU. 4. Replace the LD unit. 5. Replace the IPU 6. Replace the harness between LDB (Synchronizing detector board) and IPU.
Code: SC230-01 ... SC230-04
Description: SC230- 01 D FGATE ON error: Bk SC230- 02 D FGATE ON error: Cy SC230- 03 D FGATE ON error: Ma SC230- 04 D FGATE ON error: Ye The FGATE signal did not turn ON within the specified time (sec.) after the writing process of the corresponding color started.
Causes: • Image processing ASIC defective on IPU • Harness between IPU and LDB defective
Remedy: 1. Turn the main power OFF/ON. 2. Reconnect the connectors between IPU and controller board. 3. Replace the IPU.
