Turn the bolt of the left/right support
leg so that the distance a between the
two rubber feet at the rear and the hori-
zontal size plate of the copyboard glass
is 0.2 ±0.1 mm (approximately a gap
into which two sheets of copy paper of
2
64 /m may be inserted) when the ma-
chine is closed (i.e., the rubber feet at
the front are in contact with the
copyboard glass).
After making the adjustment, be sure to
tighten the nut to lock.
2) After making the adjustment, check to
make sure that the machine's rubber feet
at the front are firmly in contact with
the copyboard glass; otherwise, adjust
the height of the magnet at the front.

1.1.2 Adjusting the Original Stop Position

Be sure to perform "Adjusting the Height
of the Machine" in advance; be sure to per-
form "Correcting the Original Skew," "Ad-
justing the Distance to the Horizontal Size
Plate," and "Adjusting the Original Leading
Edge Stop Position," in the order indicated.
