Pump Motion
Timeout Pump shift timeout
The target position could not be reached
within a predicted operation time +3
seconds during pump operation or no
sensor has been detected during a pump
operation involving sensor detection. <Supplement>
-If the carriage travels heavily towards
the stop position: A mechanical load
error may be suspected.
-Otherwise: The sensor in the purge
unit may be at fault.

Again
Pump Motion
Error Purge motor error
A PWM duty of 100% has lasted for 200
msec in a pump operation. <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. The encoder sensor may be at fault.
2F24 Cannot cut paper.

CR Position Err
Restart Printer 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. Check the carriage HP sensor in I/O
mode.
<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 carriage HP 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.
