Power On Non-ejection detection error
Again As a result of nozzle checking made by the
Eject. Detect head management sensor unit:
Err 1. All 640 nozzles in a nozzle line are non-
discharging.
2. At least 50 nozzles have been found
mismatched in a nozzle line of 640 nozzles
since the last session of detection.

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/
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.
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.
Change to appropriate paper.
1. Check to see if the loaded paper
permit calibration.
2. Check calibrated printed matter for
soiling and other defects.
3. Check the nozzle pattern
1. Check the parts counter in service
mode and replace the multisensor unit.
2. Initialize the counter for the
replacement unit mounted. (It is
recommended to estimate the usage
status of other units coming to the end
of their service life and replace them as
needed.)
Check the cover.
Check the sensor (I/O mode).
