5. Troubleshooting
A. PF-P310 does not work with start button or test feed button.
(Remedy 1)
Adjust feed clutch solenoid position so that the clearance
between clutch lever and clutch stopper is 0.5 to 1 mm
(0.02" to 0.04") while feed clutch solenoid is on.
NOTE
- Fix feed clutch solenoid so that feed clutch solenoid
will not hit clutch lever.
(Remedy 2)
- Check on microswitch position or replace microswitch
after removing feed tray. Remove feed tray by removing
two M5 x 10 screws and spring from the both end of
spring shaft.
- Position microswitch so that actuator ON position where
click sound is heard is 2 to 4 mm (0.008" to 0.16") above
feed tray.
(Remedy 3)
Replace switch or whole P.C. Board.
