Description: SBU Communication Error • The machine cannot detect that the Scanner Carriage is connected. • The machine cannot communicate with the Scanner Carriage, or the communication data is incorrect. • The configuration of FPGA is not completed. Error detection timing: At the time of applying power source for scanner (when the main power is turned ON or when the machine returns from energy save mode)
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 – BiCU connector • BiCU – IOB connector 2. Scanner carriage defective Replace the scanner carriage. 3. BiCU defective Replace the BiCU. 4. IOB defective Replace the IOB. 5. Harness defective Replace the following harnesses. • Scanner Carriage – BiCU harness • BiCU – IOB harness
Code: SC195-00
Description: Machine 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: Re-enter the machine serial number.
Code: SC202-00
Description: Polygon Motor Error After Polygon motor is stabilized, the ready signal is at the H level for 20 seconds consecutively.
Causes: • Polygon motor defective • IOB defective
Remedy: • Polygon motor defective 1. Confirm that the connector between laser unit and IOB is firmly connected. If necessary, connect the connector all the way in. 2. If the connector is broken, shorted, or grounded, replace the connector. 3. Replace the laser unit. • IOB defective 1. Update the engine software to the latest version. 2. Replace the IOB.
Code: SC220-00
Description: Leading Edge: LD synchronization detection error The leading edge LD synchronization detection signal was not output within the specified time (sec.) while the polygon mirror motor was operating at normal speed. Error detection timing; During the startup operation of the machine or during printing.
Remedy: 1. Turn the main power OFF/ON. 2. Check for condensation on the mirrors and lenses. 3. Reconnect the connectors between LDB and IOB, and between IOB and BiCU. 4. Replace the laser unit. 5. Replace the BiCU. 6. Replace the harness between LDB and IOB, and between IOB and BiCU. 7. Replace the IOB.
Code: SC270-00
Description: GAVD Communication Error The communication is not performed normally between CPU and image writing ASIC. Error detection timing; Only when initial setting is executed.
Causes: • Image writing ASIC defective • Interface circuit between CPU and image writing ASIC defective
Remedy: 1. Turn the main power OFF/ON. 2. Replace the BiCU.
Code: SC303-00
Description: Charger Current Error When the charging voltage is applied by changing the voltage in three levels, the current value is less than 20uA in one of three levels.
Causes: • Connector defective or disconnected • Power pack defective • IOB defective
Remedy: • Connector defective or disconnected Reconnect the following connectors. Then perform a conduction inspection. If there is no conduction, replace the connector. • Drum Unit – Power Pack connector • Power Pack – IOB connector • Power pack defective Replace the power pack. • IOB defective Replace the IOB.
