Polygon Motor (M5) Error

After Polygon motor (M5) is stabilized, the ready signal is at the H level for 20 seconds consecutively.

• Polygon motor (M5) defective
• IOB (PCB17) defective

• Polygon motor (M5) defective
  
  1. Confirm that the connector between the laser unit and IOB (PCB17) 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 (PCB17) defective
  
  1. Update the engine software to the latest version.
  2. Replace the IOB (PCB17).

Leading Edge: LD synchronization detection error

The leading edge LD synchronization detection signal did 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.

• Laser unit defective (Synchronization optical system defective, LDB (PCB5) defective, LD defective)
• BiCU (PCB16) defective (Image writing ASIC defective)
• IOB (PCB17) defective
• LDB (PCB5) – IOB (PCB17), IOB (PCB17) – BiCU (PCB16) harness broken, or connector disconnected

1. Turn the main power OFF/ON.
2. Check for condensation on the mirrors and lenses.
3. Reconnect the connectors between LDB (PCB5) and IOB (PCB17), and between IOB (PCB17) and BiCU (PCB16).
4. Replace the laser unit.
5. Replace the BiCU (PCB16).
6. Replace the harness between LDB (PCB5) and IOB (PCB17), and between IOB (PCB17) and BiCU (PCB16).
7. Replace the IOB (PCB17).

GAVD Communication Error

The communication is not performed normally between CPU and image writing ASIC.

Error detection timing; Only when the initial setting is executed.

• Image writing ASIC defective
• Interface circuit between CPU and image writing ASIC defective

1. Turn the main power OFF/ON.
2. Replace the BiCU (PCB16).
