1
Checking ACTUATOR NO PAPER for shape and operation
Does ACTUATOR NO PAPER operate smoothly?
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)?
Go to step 2.
Replace
ACTUATOR NO
PAPER.
2
Checking PLATE ASSY BTM
Fit the empty Paper Cassette.
Is the flag of ACTUATOR NO PAPER located in between
sensor detecting point?
With tool
Go to step 3.
Without tool
Go to step 4.
Replace PLATE
ASSY BTM.
(RRP2.5, 3.5, 4.5)

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
ACTUATOR NO PAPER up and down. Does the number
increase one by one, as ACTUATOR NO PAPER
operates?
Checks by Chapter 2 Diagnostic [Sensor/Switch Check].
Replace
HDVS/MCU.
(RRP12.10)
Go to step 5.
4
Checking SENSOR NO PAPER (2)
Remove EP CARTRIDGE.
Close COVER OPEN (PL1.1.2).
Remove Paper Cassette.
Put the hand from the tray insertion space, move
ACTUATOR NO PAPER up and down. Is each voltage
across P/J24-8 <=> P/J24-7 and P/J24-3 <=> P/J24-2,
0VDC when ACTUATOR NO PAPER is moved up, 3.3VDC
when down?
Replace
HDVS/MCU.
(RRP12.10)
Go to step 5.
5
Checking the power to SENSOR NO PAPER
Remove EP CARTRIDGE.
Is each voltage across P/J24-6 <=> P/J24-7 and P/J24-1
<=> P/J24-2 on HVPS/MCU, 3.3 VDC?
Go to step 6. Go to step 8.
