Explanation/Detection sequence
(Small LCD)
Only for iPF750 series 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.)
VHT (heater drive drive power supply for
printhead) error
VHT has gone below or above the rating.
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
iPF6300/830 or newer main controller PCB error.
Left printhead only. VHT leak detection error of left printhead,
in case of VHT exceeds rated value or falls
Possible to occur on below the rated value.
iPFX400 or newer models.
Right printhead or a single VHT leak detection error of right
printhead printhead, in case of VHT exceeds rated
value or falls below the rated value.
Possible to occur on
iPFX400 or newer models.
Possible to occur on VHT leak detection error of right and left
iPFX400 or newer models. printhead or a single printhead, in case of
VHT exceeds rated value or falls below the
rated value.
Detected that a carriage unit of a legacy
model has been mounted (iPF8300/6300/
6350 only).
Supply valve motor error of the left ink
tank.
Drove supply valve motor. The movement
was not detected.
Supply valve motor error of the right ink
tank.
Drove supply valve motor. The movement
was not detected.
Spectrophotometer unit won't return
signals.
UART communication error.
(Data transfer volume in consistency,
checksum error etc.)
When transmitting specified pulses to
spectrophotometer carriage motor, the
spectrophotometer carriage unit won't
respond to spectrophotometer carriage HP
sensor.

Remedial Action
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/
