Step Check points Solutions
1 Is the actuator of the paper exit sensor dam-
aged?
Replace the paper exit sensor.
2 Is the cable firmly connected between the paper
exit sensor and the main PBA (CN20)?
Insert the cable firmly to the connector.

broken?
Replace the cable.
4 If no problem is found in the steps above, the
paper exit sensor or main PBA may be defective.
Replace the paper exit sensor and then the main
PBA.
Step Check points Solutions
1 Is the paper already used (once printed) and
hard to be separated from each other due to
static electricity?
Use appropriate paper.
2 Is the machine exposed to extreme temperature
or humidity? (Refer to P.2-8 "2.10 Operating
Environmental Condition".)
Choose an environment appropriate for operating
the machine.
3 Is the paper pickup roller or separation pad unit
dirty or worn out?
Wipe the dirt off with a soft dry cloth. If very dirty,
soak the cloth with water and squeeze it tightly
before wiping the dirt off.
4 Are the separation fingers (in the optional
recording paper tray) bent or damaged?
Insure that the separation fingers are clean and
undamaged. The fingers should be parallel with
one another and perpendicular with the recording
paper tray.

the recording paper?
Clean the feeding course.
