FIP2.7 SENSOR LOW PAPER (PL6.1.4, PL7.1.4)
Step
Check Yes No
Possible causative parts:
SENSOR LOW PAPER (PL6.1.4, PL7.1.4)
ACTUATOR LOW PAPER (PL6.1.5, PL7.1.5)
PLATE ASSY BTM (PL3.1.10, PL4.1.10)
HARNESS ASSY LOW1 (PL6.1.2, PL7.1.2)
LVPS (PL12.1.5)
HVPS/MCU (PL12.1.19)
1
Checking ACTUATOR LOW PAPER for operation
Install Paper Cassette.
Does ACTUATOR LOE PAPER operate smoothly, when
PLATE ASSY BTP is pushed and released by the hand?
Does the flag go into the detection point of the sensor,
when PLATE ASSY BTM is released (Actuator is pushed
up), and out of the detection point, when pushed down?
With tool
Go to step 2.
Without tool
Go to step 3.
Replace
ACTUATOR LOW
PAPER.
2
Checking SENSOR LOW PAPER for operation (1)
Remove EP CARTRIDGE.
Close COVER OPEN (PL1.1.2).
Remove Paper Cassette.
Put the hand in the tray insertin space, move ACTUATOR
LOW PAPER. Does the number increase one by one, as
ACTUATOR LOW PAPER moves?
Checks by Chapter 2 Diagnostic [Sensor/Switch Check].
Replace
HDVS/MCU.
(RRP12.10)
Go to step 3.
3
Checking HARNESS ASSY LOW1 for continuity
Remove HARNESS ASSY LOW1.
Is J260 <=> J26 continuous normally?
Go to step 4.
Replace
HARNESS ASSY
LOW1.
4
Checking SENSOR LOW PAPER (2)
Replace SENSOR LOW PAPER. (RRP6.9)
Does the problem still occur, after replacement?
Replace
HDVS/MCU.
