When the result of non-ejection detection is
as follows:
・Error code assuming broken flexible cable
When the result of non-ejection detection is
as follows:
Complete non-ejection (640 nozzles) of
EVEN line or ODD line.
・Error code assuming broken flexible cable
or contact failure (data line).
When the result of non-ejection detection is
as follows:
・Error code assuming a head failure such as
broken heater board of head.
The shutter HP sensor did not respond at
Only for iPF750 series
startup and at switching of platen shutter at
printing.
The optical axis of the head management
Only for iPF750 series
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.）

Explanation/Detection sequence
Complete non-ejection of one line in 1
chip.
(In either A line or B line, a complete
non-ejection of 1280 nozzles)
or contact failure (heat enable line).
More than half of 640 nozzles in EVEN line
or ODD line have non-ejection (more than
320 nozzles).

drive unit or
sensor
①Check whether
any foreign
matter such as
paper slip
exists on the

sensor optical
axis.
②Light
interception
due to ink
accumulation.
⇒Remove the

the unit.
③Check
connection of

④Main PCB
(Check the fuse/
Replace the

been attached
to optical
