Description: Laser synchronizing detection error: start position [K]: LD2 The laser synchronizing detection signal for the start position of the LDB [K], [C], [M], [Y] is not output for 600 ms after LDB unit turns on while the polygon motor is rotating normally.
Causes: The laser fails to reach the photo detector. Defective GAVD. Defective LD driver. Defective LDB. Defective BCU.
Remedy: • Turn the main power switch off and on. • Replace the laser optics housing unit. • Replace the BCU.
Code: 221-02
