2F42 Hardware error.
03800500-2F42
Turn off printer,wait,
then turn on again.
When the result of non-ejection detection is
as follows:
Complete non-ejection of one line in 1
chip.
(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).
Go to
★
2F2F/2F30 (P3-6).
See 2F2F for the
priority of error
detection.
2F43 Hardware error.
03800500-2F43
Turn off printer,wait,
then turn on again.
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).
Go to ★
2F2F/2F30 (P3-6).
See 2F2F for the
priority of error
detection.
2F44 Hardware error.
03800500-2F44
Turn off printer,wait,
then turn on again.
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.
Go to
★
2F2F/2F30 (P3-6).
See 2F2F for the
priority of error
detection.
2F46 Hardware error.
03130031-2F46
Turn off printer,wait,
then turn on again.
The shutter HP sensor did not respond at
startup and at switching of platen shutter at
printing.
Check the platen
shutter HP sensor

drive unit or
sensor
2F47 Hardware error.
3800500-2F47
Turn off printer,wait,
then turn on again.
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.
）
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
connection of
the head
management
sensor’s
connector.
④
Main PCB
(Check the fuse/
Replace the
PCB.)
⑤
A large amount
of ink mist has
been attached
to optical
element.
⑥
Replace the
head
management
sensor.
