Description: Serial number error Comparison of the product identification code in the machine serial number (11 digits).
Causes: The product identification code in the machine serial number (11 digits) does not match.
Remedy: 1. Turn the power OFF then ON. 2. Check the serial number.
Code: SC202-00
Description: Polygon mirror motor: ON timeout error After the polygon mirror motor turned on, or within the specified time (sec.) after the rpm’s changed, the motor did not turn normally.
Causes: • Polygon mirror motor or polygon motor driver defective • The interface harness to the polygon motor driver damaged or not connected correctly • EGB (PCB1) defective • PSU (PCB4) defective (polygon power supply, fuse defective) • AC power supply voltage error
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1. Check the connection between the laser unit and the EGB (PCB1). 2. Check the PSU 24V output voltage. 3. Replace the laser unit. 4. Replace the EGB (PCB1). 5. Replace the PSU (PCB4).
Code: SC203-00
Description: Polygon mirror motor: OFF timeout error The polygon motor fails to stop within the specified time after receiving the signal to stop.
Causes: • Polygon mirror motor or polygon motor driver defective • The interface harness to the polygon motor driver damaged or not connected correctly • EGB (PCB1) defective • PSU (PCB4) defective (polygon power supply, fuse defective) • AC power supply voltage error
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1. Check the connection between the laser unit and the EGB (PCB1). 2. Check the PSU 24V output voltage. 3. Replace the laser unit. 4. Replace the EGB (PCB1). 5. Replace the PSU (PCB4).
Code: SC204-00
Description: Polygon mirror motor: Lock signal error An error is detected during the polygon mirror motor rotation.
Causes: • Polygon mirror motor or polygon motor driver defective • The interface harness to the polygon motor driver damaged or not connected correctly • EGB (PCB1) defective • PSU (PCB4) defective (polygon power supply, fuse defective) • AC power supply voltage error
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. 1. Check the connection between the laser unit and the EGB (PCB1). 2. Check the PSU 24V output voltage. 3. Replace the laser unit. 4. Replace the EGB (PCB1). 5. Replace the PSU (PCB4).
Code: SC220-01
Description: Laser synchronization detection error (K) The synchronization detection signal (periodic write/scan signal) absent during the machine startup or printing after power is turned ON.
Causes: • Laser unit defective (Synchronization detection board defective, LDB defective) • EGB (PCB1) defective • Harness between the synchronization detection board and LDB.
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. • Check for condensation. • Replace the laser unit. • Replace the EGB (PCB1).
Code: SC220-02
Description: Laser synchronization detection error (C) The synchronization detection signal (periodic write/scan signal) absent during the machine startup or printing after power is turned ON.
Causes: • Laser unit defective (Synchronization detection board defective, LDB defective) • EGB (PCB1) defective • Harness between the synchronization detection board and LDB.
Remedy: Check if the SC occurs by turning the power OFF then ON. If the SC occurs again, do the following steps. Check if the SC reoccurs by cycling the power after each step. • Check for condensation. • Replace the laser unit. • Replace the EGB (PCB1).
