FIP1.30 SENSOR LOW PAPER

Step
Possible causes:
SENSOR LOW PAPER (PL7.1.4)
ACTUATOR LOW PAPER (PL7.1.5)
PLATE ASSY BTM (PL4.1.10)
HARNESS ASSY LOW1 (PL7.1.2)
LVPS (PL12.1.5)
HVPS/MCU (PL12.1.19)
Checking ACTUATOR LOW PAPER for operation
Install Paper Cassette.
Does ACTUATOR LOW PAPER operate smoothly,
when PLATE ASSY BTP is pushed and released by the
