• Code: 2F46
• Display: Hardware error. 03130031-2F46 Turn off printer,wait, then turn on again.
• Description: The shutter HP sensor did not respond at startup and at switching of platen shutter at printing.
• Remedy: Check the platen shutter HP sensor (I/ O Display). Check/ replace the platen shutter drive unit or sensor

• Code: 2F47
• Display: Hardware error. 3800500-2F47 Turn off printer,wait, then turn on again.
• Description: The optical axis of the head management sensor unit has been intercepted for some reasons. The amount of LED luminescence and the level of detection signal of diode light receiving sensitivity has gone beyond the predefined range. (determines the level of APCCHK)(It's not a problem of printhead or ink supply system.)
• Remedy: 1. Check whether any foreign matter such as paper slip exists on the head management sensor optical axis. 2. Light interception due to ink accumulation.-> Remove the ink/ Replace the unit. 3. Check connection of the head management sensor's connector. 4. Main controller PCB (Check the fuse/ Replace the PCB.) 5. A large amount of ink mist has been attached to optical element. 6. Replace the head management sensor.

• Code: 2F48
• Display: Hardware error. 03130031-2F48 Turn off printer, wait, then turn on again.
• Description: VHT (heater drive drive power supply for printhead) error VHT has gone below or above the rating.
• Remedy: iPF6300 series 1. Replace the printhead. 2. Replace the main controller PCB. iPF8300 series 1. Replace the printhead. 2. Replace the CR relay board. 3. Check/ replace the long flexible cable. 4. Replace the main controller PCB.

• Code: 2F49, 2F50, 2F51
• Display: Hardware error. 03130031-xxxx Turn off printer, wait, then turn on again.
• Description: Printhead short-circuited detected. Prior to VH power on, it has been detected that the printhead had been damaged due to paper jam etc, and ink went inside the terminal area causing near short-circuit. 2F49: L side printhead 2F50: R side printhead 2F51: LR both printhead
• Remedy: iPF6300 series 1. Replace the printhead 2. Replace the main controller PCB. iPF8300 series 1. Replace the printhead 2. Replace the CR relay board 3. Check/ replace the long flexible cable. 4. Replace the main controller PCB.

• Code: 2F4A
• Display: Hardware error. 03130031-2F4A Turn off printer, wait, then turn on again
• Description: main controller PCB error.
• Remedy: Replace the main controller PCB.

• Code: 2F4D
• Display: Hardware error. 03130031-2F4D Turn off printer, wait, then turn on again.
• Description: VHT leak detection error of left printhead, in case of VHT exceeds rated value or falls below the rated value.
• Remedy: For iPF6400 series, 1. Replace the printhead. 2. Replace the main controller PCB. For iPF8400/9400 series, 1. Replace the printhead. 2. Replace the CR relay board. 3. Check and replace the long flexible cable printed circuit. 4. Replace the main controller PCB.

• Code: 2F4F
• Display: Hardware error. 03130031-2F4F Turn off printer, wait, then turn on again.
• Description: VHT leak detection error of right and left printhead or a single printhead, in case of VHT exceeds rated value or falls below the rated value.
• Remedy:

• Code: 2F52
• Display: Hardware error. 03130031-2F52 Turn off printer, wait, then turn on again.
• Description: Detected that a carriage unit of a legacy model has been mounted (iPF8300/6300/ 6350 only).
• Remedy: Replace with an appropriate carriage unit. 1. Replace with an appropriate carriage unit. 2. Replace the printhead. 3. Replace the main controller PCB
