FIP1.29 SENSOR NO PAPER

Step
Possible causes:
SENSOR NO PAPER (PL5.1.38, PL7.1.38)
ACTUATOR NO PAPER (PL5.1.6, PL7.1.14)
150 FEEDER ASSY (PL5.1.1)
HARNESS ASSY TRAY1 (PL5.1.37)
HARNESS ASSY TRAY2 (PL7.1.36)
HARNESS ASSY CHUTE (PL12.1.17)
HVPS/MCU (PL12.1.19)
PLATE ASSY BTM (PL2.1.10, PL4.1.10)
LVPS (PL12.1.5)
550 FEEDER ASSY (PL7.1.10)
Checking ACTUATOR NO PAPER for shape and oper-
ation
Does ACTUATOR NO PAPER operate smoothly?
1 Is the flag between the sensor detecting point when
ACTUATOR NO PAPER is low (there is no paper), and
out of the detecting point when ACTUATOR NO PAPER
is high (there is paper)?
Checking PLATE ASSY BTM
Fit the empty Paper Cassette.
2
Is the flag of ACTUATOR NO PAPER located in
between sensor detecting point?
Checking SENSOR NO PAPER (1)
Remove EP CARTRIDGE.
Close COVER OPEN (PL1.1.2).
Remove Paper Cassette.
Put the hand from the tray insertion space, and move
3
ACTUATOR NO PAPER up and down.
Does the number increase one by one, as ACTUATOR
NO PAPER operates?
Check using Chapter 2 Diagnostic [Sensor/Switch
Check].
Checking SENSOR NO PAPER (2)
Remove EP CARTRIDGE.
Close COVER OPEN (PL1.1.2).
Remove Paper Cassette.
4 Put the hand from the tray insertion space, move
ACTUATOR NO PAPER up and down.
Is each voltage across P/J24-8(+) and P/J24-7(-) and
P/J24-3(+) and P/J24-2(-), 0VDC when ACTUATOR
NO PAPER is moved up, 3.3VDC when down?
Checking the power to SENSOR NO PAPER
Remove EP CARTRIDGE.
5
Is each voltage across P/J24-6(+) and P/J24-7(-) and
P/J24-1(+) and P/J24-2(-) on HVPS/MCU, 3.3 VDC?
