• Code: 03810213-2585
• Description: Tank level error 1. When head cleaning was executed automatically at ink level 1,insufficiency of ink was detected. Opening the ink tank cover recovers this error. The error recovery operation is continued until it is cancelled using the STOP key.
• Causes: Ink tank, ink tank unit, or main controller PCB
• Remedy: 1. Replace the ink tank. 2. Cable continuity check If continuity of the cable between the ink tank unit and the main controller PCB is abnormal, replace the cable. 3. Replace the ink tank unit. 4. Replace the main controller PCB.

• Code: 03810213-2595

• Code: 03830101-2521
• Description: Ink tank is not installed.(This error occurs when the ink tank is replaced.) When the ink tank was replaced, the closed state of the ink cover was detected with the ink tank removed.
• Causes: Operation method, ink tank, ink tank cover sensor, ink tank unit, or main controller PCB
• Remedy: 1. Operation check Install the ink tank. 2. Visual check Remove foreign substances from the ink tank contacts and ink cover sensor if any. 3. Replace the ink tank. 4. Ink tank cover sensor Check for normal operation. If the operation is abnormal, replace the ink tank cover sensor. 5. Cable continuity check If continuity of the cable between the ink tank cover sensor and the main controller PCB is abnormal, replace the cable. 6. Replace the ink tank unit. 7. Cable continuity check If continuity of the cable between the ink tank unit and the main controller PCB is abnormal, replace the cable. 8. Replace the main controller PCB.
