Description: Laser synchronizing detection error: end position [M] The laser synchronizing detection signal for the end position of LDB [K], [C], [M], [Y] is not detected for 200 ms after the LDB unit turned on when detecting the main scan magnification.
Causes: Disconnected or defective I/F harness to laser synchronizing detection unit. Defective laser synchronizing detection board. The laser fails to reach the photo detector. Defective GAVD. Defective LD board or driver. Defective BCU.
Remedy: • Turn the main power switch off and then back on. • Replace the laser optics housing unit. • Replace the harness. • Replace the BCU.
