Description: <D0B4> D White level detection error The white level cannot be adjusted to the second target level within the target during auto gain control.
Causes: • Condensation in the scanner unit • Scanner Carriage defective • Harness defective • Connector defective (disconnected, loose) • White plate dirty or installed incorrectly • MPU defective
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. Reconnect the following connectors: • Scanner Carriage - MPU harness (FFC) • SBU - LEDB harness (FFC) 2. Check the white reference seal that attached back of sheet-through exposure glass. Replace the sheet-through exposure glass, if dirty or damaged. 3. Replace the scanner carriage. 4. Replace the MPU. 5. Replace the following harnesses: • Scanner Carriage - MPU harness (FFC)
Code: 144-00
Description: <D0B2,D0B3> D Scanner communication error The machine cannot communicate in the MPU (PCB7), or the communication result is unexpected.
Causes: • Unexpected communication • Power failure
Remedy: 1. Reconnect the harness of the CIS unit (PCB4). 2. Replace the following parts. • Replace the MPU (PCB7). • Replace the harness of the CIS unit (PCB4).
Code: 144-00
Description: <D0B4> D SBU Communication Error • The machine cannot detect that the SBU is connected. • The machine cannot communicate with the SBU. • The communication data is incorrect.
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. Reconnect the following connectors: • Scanner Carriage - MPU harness (FFC) 2. Replace the Scanner Carriage. 3. Replace the MPU. 4. Replace the following harnesses: • Scanner Carriage - MPU harness (FFC)
Code: 161-20
Description: <D0B4> D MPU error (DRAM initialization failure) An error occurred during performed every time the machine is turned on, or returns to full operation from energy saving mode.
Causes: • MPU board defective (Macaron/ DRAM device connection error) • DRAM device defective
Remedy: • Reconnect the all connectors on MPU board if they are disconnected, or loose. • Replace the MPU.
Code: 202-00
Description: <D0B2,D0B3,D0B4> D Polygon motor: ON timeout error Polygon motor locking has not been detected when 8 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 (PCB7) • Replace the PSU (PCB1)
Code: 203-00
Description: <D0B2,D0B3,D0B4> D 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 (PCB7). • Replace the PSU (PCB1).
