• Code: 2F2A
• Display: Hardware error. 03130031-2F2A Turn off printer, wait, then turn on again.
• Description: Cannot detect the LF home position The LF home position could not be detected on LF homing during initialization.
• Remedy: 1. Check the sensor (I/O mode check). 2. Replace the feed roller encoder sensor. 3. Replace the encoder film. 4. Replace the feed motor/belt/ adjust the belt tension. 5. Replace the long flexible cable. <Supplement> -If the motor could not be run at all: A. A mechanical load error may be suspected. B. The motor or drive circuit may be at fault. -If the carriage has resulted in an error after moving at a constant speed: The feed roller HP sensor may be at fault. -If the carriage has run more or less out of control and resulted in an error, the encoder sensor may be at fault. When FU2802 blows out on iPF6300/ 6400 series -Replace the main controller PCB.

• Code: 2F2B
• Display: Hardware error. 03130031-2F2B Turn off printer, wait, then turn on again.
• Description: LF operation failure (LF operation disabled) A pump duty of 100% has lasted for 200 msec during LF operation.
• Remedy: 1. Replace the feed roller encoder sensor. 2. Replace the feed motor. <Supplement> -If the motor could not be run at all or has resulted in an error after moving by a slight distance: A. A mechanical load error may be suspected. B. The motor or drive circuit may be at fault. -If the carriage has run more or less out of control and resulted in an error, the encoder sensor may be at fault. When FU2802 blows out on iPF6300/ 6400 Series -Replace the main controller PCB.

• Code: 2F2C
• Display: Hardware error. 03130031-2F2C Turn off printer, wait, then turn on again.
• Description: Cassette shift timeout -The target position could not be reached within a predicted operation time + 3 seconds during cassette operation. -No sensor has been detected during a pump operation involving sensor detection.
• Remedy: <Supplement> -If the carriage travels heavily near the stop position, a mechanical load error may be suspected. -Otherwise, the cassette unit sensor may be at fault.

• Code: 2F2D
• Display: Cassette not working. Turn off printer, wait, then turn on again.
• Description: Cassette operation disabled A PWM duty of 100% has lasted for 200 msec in a cassette operation.
• Remedy: 1. Check the cassette motor and the drive circuit. 2. Check the cassette encoder sensor.

• Code: 2F2E
• Display: Hardware error. 03130031-2F2E Turn off printer, wait, then turn on again.
• Description: Roll shift timeout No sensor has been detected during a roll operation involving sensor detection.
• Remedy:

• Code: 2F2F
• Display: Hardware error. 03800500-2F2F Turn off printer, wait, then turn on again.
• Description: Non-ejection detection error As a result of nozzle checking made by the head management sensor unit: 1. All 640 nozzles in a nozzle line are nondischarging. 2. At least 50 nozzles have been found mismatched in a nozzle line of 640 nozzles since the last session of detection.
• 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 the head management sensor's connector connection 4. If Service mode nozzle check pattern printing is no problem, replace the head management sensor unit. Reference 1) As for the detection condition 1. above, in the iPF650/750, iPF6300/6350, and iPF8300 series or later, the error codes are broken up into 2F40,2F41,2F42,2F43,2F44, and 2F47 depending on the non-ejection conditions. Reference 2) Error 2F2F,2F40,2F41,2F42,2F43,2F44, and 2F47 are detected in the following order. 1. Determines signal level (2F47) of head management sensor 2. Determines complete non-ejection of all colors (2F40) 3. Determines multiple mismatches (2F2F) 4. Determines complete non-ejection of a single color (2F41) 5. Determines complete non-ejection of one line (2F42) 6. Determines complete non-ejection of 640 nozzles (2F43) 7. Determines non-ejection of more than 320 nozzles (2F44) Reference 3) The amount of change (between non-ejecting and ejecting nozzle counts) from the last session of nozzle checking is defined as the amount of mismatch.

• Code: 2F30
• Display: Hardware error. 03800500-2F30 Turn off printer, wait, then turn on again.
• Description: Non-ejection detecting position error No detectable region has been found during non-ejection position adjustment.
• Remedy:

• Code: 2F32
• Display: Multi-sensor error Turn off printer, wait a while, then turn it on again.
• Description: Faulty multisensor Light quantity adjustment of multisensor failed. Or, outside light entered during multisensor light quantity adjustment.
• Remedy: 1. Retry the adjustment with the effect of outside light, such as that of the afternoon sun, being removed. 2. Check the position at which the multisensor is installed. 3. Replace the multisensor.
