• Description: Abnormal H3V voltage at starting up, cleaning, and print starting (support number : 4801)
• Causes: Abnormal H3V voltage is detected at starting up, cleaning, and print starting.
• Remedy: 1 Reboot the printer.

• Code: EC21 2F62
• Description: VHTR leak error at rebooting (support number : 1478)
• Causes: The printer does not recover by rebooting after VHTR leak error at starting up, cleaning, and print starting.
• Remedy: 1 Perform [DIAGNOSIS > CR_SYSTEM_CHECK] to diagnose carriage system. No problem Go to 2. Abnormal • Problem in ACC. SENSOR CHECK or CR VIBRATIONCHECK Replace CARRIAGE UNIT. • Problem in LONG FFC CHECK or CRC value changes after turning the printer off and back on Replace FLEXIBLE CABLE UNIT. 2 Remove the print head and check the condition of print head contacting part. Proper condition Replace the print head. Improper condition Go to 3. 3 Clean the surface of the print head contacting part. (The waste cloth without a nap must be used.) The problem is resolved Complete. The problem is not resolved Go to 4. 4 Replace the print head. The problem is resolved Complete. The problem is not resolved Replace MAIN PCB UNIT. (After replacement, perform PCB replacement mode and necessary adjustments.)

• Code: EC21 2F63
• Description: Print head contact error at print head replacement (support number : 1479)
• Causes: Direct diode sensor detects print head contact failure at print head replacement.
• Remedy: 1 Remove the print head and check the condition of print head contacting part. Proper condition Go to 2. Improper condition Clean the surface of the print head contacting part. (The waste cloth without a nap must be used.) 2 Perform [DIAGNOSIS > CR_SYSTEM_CHECK] to check the result of LONG FFC CHECK and if CRC value changes after turning the printer off and back on (When CRC value changes, wires are broken).
