Is PPS1 fully operational? Check
the input data using I/O Check.
YES Perform steps 6 and onward.
5 Does the voltage across CN3A-2
on PWB-A (PF-106) and GND
change from LOW to HIGH when
PPS1 is blocked?
YES Change PWB-A (PF-106),
PWB-A (PF-108/PF-110), or
PWB-A (Cassette Main
Board), in that order.
NO Change PPS1.
6 Is paper fed up to S1 when paper
is loaded in Lift 2 only and the
drawer is slid into the copier?
YES Perform steps 8 and onward.
7 Check P2CL for operation.
Does the voltage across CN7A-6
on PWB-A (PF-106) and GND
change from DC24V to DC0V
when step 6 is performed again?
YES Check various parts for possi-
ble overload and, if they are
okay, change P2CL.
NO Change PWB-A (PF-106),
PWB-A (PF-108/PF-110),
PWB-A (Cassette Main
Board), or PWB-A, in that
order.
8 Check P1CL for operation.
Does the voltage across CN7A-8
on PWB-A (PF-106) and GND
change from DC24V to DC0V
when step 6 is performed again?
NO Change PWB-A (PF-106),
PWB-A (PF-108/PF-110),
PWB-A (Cassette Main
Board), or PWB-A, in that

Does the “S1S” input signal
change from 0 to 1 when the
drawer loaded with paper is slid
into the copier?
YES Perform steps 11 and onward.
10 Does the voltage across CN3A-5
on PWB-A (PF-106) and GND
change from LOW to HIGH when
step 9 is performed again?
YES Change PWB-A (PF-106),
PWB-A (PF-108/PF-110), or
PWB-A (Cassette Main
Board), in that order.
NO Change S1.
11 Is the Paper Feed Roll or Separa-
tor Roll deformed, worn, or dirty
with paper dust?
YES Clean or change the Paper
Feed Roll or Separator Roll.
12 Check BCL for operation.
Does the voltage across CN7A-2
on PWB-A (PF-106) and GND
change from DC24V to DC0V
when the Start key is pressed?
YES Check various parts for possi-
ble overload and, if they are
okay, change P1CL or BCL.
NO Change PWB-A (PF-106),
PWB-A (PF-108/PF-110),
PWB-A (Cassette Main
Board), or PWB-A, in that
order.
