Description: Trailing edge laser detection error: [Y] [C] The laser synchronizing detection signal for LDB [Y] of the trailing edge is not detected for one second after the LDB unit turned on when detecting the main scan magnification.
Causes: • Disconnected cable from the laser synchronizing detection unit or defective connection • Defective laser synchronizing detector • Defective LDB • Defective EGB
Remedy: 1. Check the connectors. 2. Replace the laser-synchronizing detector. 3. Replace the LDB. 4. Replace the EGB.
Code: 212
