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?
Check
Is the fixing unit release spacer removed?
Is the MEDIA TYPE set to TRANSPARENCY?
Is thick paper over than 36lb (135g/m
Is the voltage at the pin 3 of the connector
P11 of the main PCB is controlled within
1.80 ± 0.10V during continuous printing?
