Check
Does self test printing have no problem?
Is over-amount of paper than specified load
on the cassette?
Does print quality improve when
recommended paper is used?
Is paper curled?
Does print quality improve when Y offset
setting is changed?
Is the jam remove cover deformed?
Does the regist sensor actuator operate
smoothly?
Is the voltage at the pin 5 of the connector P3
of the main PCB 5V when no paper passes
and 0V when paper passes?

Remedy
Check again the top margin
setting in the printing data.
Reduce the paper load below
the specified limit.
Use recommended paper.
Use recommended fresh
paper without curl.
Ajust Y offset setting to an
appropriate value.
Replace the jam remove
cover.
Reassemble the actuator
and, if the problem is not
resolved, replace the actuator.
Replace the paper feed/size-
sw PCB assy or the harness
and, if the problem remains,
replace the main PCB assy.
Replace the paper feed roller
assy.
Remedy
Remove the fixing unit
release spacer.
Set the MEDIA TYPE to
REGULAR or THICK PAPER.
Instruct the user to use the
paper whose thickness is
less than the recommended
value.
Replace the fixing unit.
