03130031-2F3B
Only for iPF750 series
Explanation/Detection sequence
Ink Supply Valve Open/Closed motor
timeout error
CS communication error
An irrecoverable communication error has
occurred communicating between the CS
chip mounted on the ink tank and the main
unit.
LF nip sensor error.
When executing nip automatic operation,
one of the following conditions is met.
-The sensor detected nip closed after the
nip completed opening operation.
-The sensor detected nip open after the nip
completed closing operation.
HP pre-ejection pump motor overload error Replace the HP maintenance jet tray
HP pre-ejection pump motor shift timeout Replace the HP maintenance jet tray
An error other than overload error or shift
timeout error has been detected for the HP
pre-ejection pump motor.
When the result of non-ejection detection is
as follows.
When non-ejection has been detected for
all nozzles of all colors
-The error code assuming a problem in the
supply system/ purge system/ main
controller PCB (electric).
When the result of non-ejection detection is
as follows:
Complete non-ejection of nozzles in 1
to 5 chip(s).
(A line EVEN/ A line ODD/ B line
EVEN/ B line ODD
Total of 2560 nozzles x 1 to 5 chip(s)
complete non-ejection)
-Error code assuming a problem in the ink
supply system/ purge system.
When the result of non-ejection detection is
as follows:
Complete non-ejection of one line in
1chip.
(In either A line or B line, a complete non-
ejection of 1280 nozzles)
-Error code assuming broken flexible cable
or contact failure (heat enable line).
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:
More than half of 640 nozzles in EVEN
line or ODD line have non-ejection (more
than 320 nozzles).
-Error code assuming a head failure such as
broken heater board of head.
The shutter HP sensor did not respond at
startup and at switching of platen shutter at
printing.
Remedial Action
1. Replace the ink supply unit.
2. Replace the main controller PCB.
1. Remove and insert the ink tank, or
replace the ink tank.
2. Check bundled wires in the ink tank
unit and the main controller PCB.
3. Replace the main controller PCB.
Check the lift cam sensor/ pressure
release switch (I/O mode)
unit.
unit.
Replace the HP maintenance jet tray
unit.
Check the platen shutter HP sensor (I/
O Display). Check/ replace the platen
shutter drive unit or sensor
