Canon FY8-13FW-000DADF-A1 Service Manual page 118

Suppose that the distance between the two
sheets of copy paper is 4 mm when the
push switch SW3 on the DADF controller
PCB is pressed once to stop the copy paper
on the copyboard and the DADF is
opened.
To decrease the sheet-to-sheet distance by
4 mm,
4/0.34 (adjustment pitch) = 12.12
the push switch SW2 must be pressed 12
times.
When the push switch SW2 is pressed 12
times and the push switch SW3 on the
DADF controller PCB is pressed once, the
copy paper will be discharged and the new
setting will be stored.
6) After "correcting the original skew,"
"adjusting the horizontal size plate,"
"adjusting the original leading edge stop
position," and "adjusting the reduced
composition mode
distance," turn off the copier and shift all
bits of the DIP switch DSW1 to OFF.
Turn on the copier, and check to make sure
that the operation of the DADF is normal.
However, if the size of the original
(length in feeding direction) is as follows,
keep bit 7 of the DIP switch DSW1 to ON.
