DC controller PCB
5V
Detects length of paper
based on combination of various
C2SZ0
input signals.
C2SZ1
5V
MFPW
Detects width of paper in
5V
association with multifeeder and
side guide plate of each cassette.
C1PW
(analog signal)
5V
C2PW
When '0', transparency sensor
OHPLED
LED turns ON. (output signal)
When '0', transparency leading
OHPSDT
edge detected.
TSSLCT
When TSSLCT is '1',
selects TS1, 2, 3, 8.
When TSSLCT is '0',
selects TS4, 5, 6, 7.
YTEP*
'0' when toner falls short of
specific value based on
combination with TSSLCT.
