Description: Scanner communication error The machine cannot communicate in the MPU, or the communication result is unexpected.
Causes: • Unexpected communication • Power failure
Remedy: 1. Reconnect the harness of the CIS. 2. Replace the following parts. • Replace the MPU. • Replace the harness of the CIS.
Code: 202-00
Description: Polygon motor: ON timeout error Polygon motor locking has not been detected when 7 seconds have elapsed after the machine turned the polygon motor ON.
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)
Remedy: • Check the harness of the laser unit (disconnected, etc.). • Check if the laser unit connector is connected. • Check if the PSU 24 V power is output. • Replace the interface harness of the laser unit. • Replace the laser unit. • Replace the MPU • Replace the PSU
Code: 203-00
Description: Polygon motor: OFF timeout error Polygon motor has not stopped when 3 seconds have elapsed after the machine turned the polygon motor 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.
Remedy: • Check the harness of the laser unit (disconnected, etc.). • Check if the laser unit connector is connected. • Check if the PSU 24 V power is output. • Replace the interface harness of the laser unit. • Replace the laser unit. • Replace the MPU. • Replace the PSU
Code: 204-00
Description: Polygon motor: Lock signal error An error is detected during the polygon motor rotation.
Causes: • The interface harness to the polygon motor driver damaged or not connected correctly. • Polygon motor or polygon motor driver defective
Remedy: • Check the harness of the laser unit (disconnected, etc.). • Check if the laser unit connector is connected. • Check if the PSU 24 V power is output. • Replace the interface harness of the laser unit. • Replace the laser unit. • Replace the MPU. • Replace the PSU.
Code: 220-00
Description: Laser synchronization detection error An error of the laser synchronizing is detected at the LD lighting.
Causes: • The interface harness to the synchronization detection unit damaged or not connected correctly. • Synchronization detection board defective • Beam does not enter photo detector.
Remedy: • Check the harness of the laser unit (disconnected, etc.). • Check if the laser unit connector is connected. • Replace the interface harness of the laser unit. • Replace the laser unit. • Replace the MPU.
Code: 302-00
Description: High voltage charge error The machine detects "1" (error) 10 times consecutively when monitoring the output error signal every 20 msec (excluding in Sleep mode or with the front door open).
