Explanation/Detection sequence
(Small LCD)
Power On Mist fan error
Again The rotation of the mist fan is not
Mist Fan Error detectable.
Power On Platen fan lock detection error
Again The lock signal has been supplied
Platen Fan Lock continuously for 3 seconds or longer, 10
seconds after the platen fan started rotating.
Power On
Again
Platen Fan Err
Power On Purge sensor error (recovery purge motor
Again HP detection error)
Purge Motor The recovery system has been driven but
Sensor Error no sensor interrupt occurs.
The recovery system has been driven to
close the cap, but the cap has not been
capped successfully.
Power On Cap motor cam positioning error
Again The recovery system has been driven but
Motor Cam Pos no sensor interrupt occurs.
Error The recovery system has been driven to
close the cap, but the cap has not been
capped successfully.
Pinch roller open detected with the pinch
roller locked.
Power On Pump shift timeout
Again The target position could not be reached
Pump Motion within a predicted operation time +3
Timeout seconds during pump operation or no
sensor has been detected during a pump
operation involving sensor detection.
Power On Purge motor error
Again A PWM duty of 100% has lasted for 200
Pump Motion msec in a pump operation.
Error
Cutting Error Cutter shift timeout
Please Cut Papr The cutter failed to reach the home position
Press (upper arrow) Key in time during a cutting operation
to Release Paper
Power On Cutter shift timeout error
Again No sensor has been detected during a cutter
Cutter Timeout operation involving sensor detection.
Power On Carriage motor HP not detectable
Again Detected only for the wide format.
CR Position Err For the narrow format, the carriage motor
Restart Printer HP can be detected when the carriage hits
the wall in a full scan following the
detection of the HP.
Power On Carriage operation disabled
Again -A PWM duty of 100% has lasted for 200
Carriage Motion msec in a carriage operation
Error -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).

Remedial Action
1. Check the bundled wires in the mist
fan drive circuit.
2. Replace the mist fan unit.
3. Replace the main controller PCB.
1. Check the bundled wires in the
platen suction fan drive circuit.
2. Replace the platen suction fan unit.
3. Replace the main controller PCB.
1. Restart with the pinch roller closed.
2. Check the sensor in I/O DISPLAY
in Service mode (Check the pinch
roller pressure release detection SW/
the release lever lock sensor.)
<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.
<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.
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.
