Explanation/Detection sequence
Carriage motor HP not detectable
Detected only for the wide format.
For the narrow format, the
carriage motor HP can be
detected when the carriage hits
the wall in a full scan following the
detection of the HP.
Carriage operation disabled
・A PWM duty of 100% has lasted
for 200 msec in a carriage
operation
・A collision has been detected in
a carriage operation (with the
speed predicted from the PWM
output value having a deviation
of 25 ips or more from the actual
speed).
Carriage shift timeout
The target position could not be
reached within a predicted
operation time + 3 seconds during
carriage operation.
Lift shift timeout
A lift operation has been
executed, but no sensor has been
detected or a sensor has
remained detected.

Remedial Action
(★: Reference fault isolation
procedure or tool)
Wide format: Check the
CHRP sensor in IO mode
and go to ★2F26 (P3-4).
Narrow format: Go to ★
2F26 (P3-4).
<Supplement>
・If the motor could not be
run at all:
A. A mechanical load error
may be suspected.
B. The motor or drive
circuit may be at fault.
・If the carriage has
resulted in an error after
moving at a constant
speed:
A. The CRHP sensor may
be at fault.
・If the carriage has run
more or less out of
control and resulted in an
error:
A. The encoder sensor
may be at fault.
<Supplement>
・If the motor could not be
run at all or has resulted
in an error after moving
by a slight distance:
A. A mechanical load error
may be suspected.
B. The motor or drive
circuit may be at fault.
・If the carriage has run
more or less out of
control and resulted in
an error:
A. encoder sensor may be
at fault.
Go to ★2F26 (P3-4).
<Supplement>
・If the carriage travels
heavily towards the
stop position, a
mechanical load error
may be suspected.
Go to ★2F26 (P3-4).
①Switch off the printer,
then back on.
②The carriage cannot
travel to the lift drive
position.
③The lift drive cam is not
engaged.
④Faulty lift drive sensor
⑤Faulty lift drive motor
