Power On Roll shift timeout
Again No sensor has been detected during a roll
Roll Motion operation involving sensor detection.

Power On Non-ejection detection error
Again As a result of nozzle checking made by the
Eject. Detect head management sensor unit:
①All 640 nozzles in a nozzle line are
Err
② At least 50 nozzles have been found
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.
①Determines signal level (2F47) of head management sensor
②Determines complete non-ejection of all colors (2F40)
③Determines multiple mismatches (2F2F)
④Determines complete non-ejection of a single color (2F41)
⑤Determines complete non-ejection of one line (2F42)
⑥Determines complete non-ejection of 640 nozzles (2F43)
⑦Determines 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.
Power On Non-ejection detecting position error
Again No detectable region has been found during
Eject. Detect non-ejection position adjustment.
