Description: Polygon motor error . The polygon motor starts operating. - The lock signal is not detected within 20 seconds. . The polygon motor starts operating. - The lock signal is detected within 20 seconds. - After a 3-second waiting time, no lock signal is detected within 20 seconds. . The polygon motor strops operating. - The lock signal is not detected within 20 seconds. . The polygon motor is operating. - The lock signal remains undetected for 0.5 seconds.
Causes: • Defective polygon motor • Defective harness
Code: 220
Description: 1st beam synchronization error A polygon motor lock is detected; the LD door is closed; the LD remains on. - The LD error (1st beam synchronization error) continues for 0.5 seconds.
Description: 2nd beam synchronization error A polygon motor lock is detected; the LD door is closed; the LD remains on. - The LD error (2nd beam synchronization error) continues for 0.5 seconds.
Description: FGATE on error A transfer belt mark is detected. - No FGATE on signal is detected within 175+50 milliseconds.
Causes: • Defective BCU
Code: 231
Description: FGATE off error A FGATE assert signal is detected. - The FGATE negate signal is not detected within 30 seconds.
Causes: • Defective BCU
Code: 241
Description: LD error An LD error continues for 0.5 seconds. (After an LD error is detected, an LD error release is written to the GAVD chip during monitoring.)
