SCAN MOTOR ERROR
CODE : 0000 0000
Error detected as a result Error detected at rst
NO MEANING
0001 Feed Motor Deviation Error
(The order from the CPU does not match the
feedback of the Feed Motor.)
0004 Feed Motor Overcurrent Error 1
(Big load is put on the motor movement
instantaneously.)
0008 Feed Motor Overcurrent Error 2
(A little load is put on the motor movement for a
long time.)
000C 0004 and 0008 occurred at the same time.
0005 0001 and 0004 occurred at the same time.
0009 0001 and 0008 occurred at the same time.

(The order from the CPU does not match the
feedback of the Scan Motor.)
0040 Scan Motor Overcurrent Error 1
(Big load is put on the motor movement
instantaneously.)
0080 Scan Motor Overcurrent Error 2
(A little load is put on the motor movement for a
long time.)
00C0 0040 and 0080 occurred at the same time.

CAUSE
< External factors >
1. Media Jamming
2. Pull or move the carriage by hands.
3. Carriage runs into a thing or hands.
4. Media is stuck because it is caught by the paper pipe.
5. Media is pulled forcedly.
6. Too heavy media is loaded.
< Machine factors >
1. The grease lubrication of the motor gear is not enough.
2. Motor is broken or end of life.
3. Servo board is broken.
4. Tool carriage xation to the belt is loose.
5. The bearing inside the idle pulley is worn out.
6. The carriage belt loses steps.
(The symptom may be improved by greasing the belt.)
7. Limit position is not appropriate.
(When the limit position is not correctly set,
it may cause a scan motor error.)
8. Power supply for motor is broken.
(When the power supply voltage for the motor is not
supplied, the motor cannot move and it results in the
motor error. )
