w Pressing the clear key while pressing the stop key initializes the folding stopper, and moves the folding stopper of
folding plate 2 to the home position.
e Open the top cover (leave the detection switch ON), and check that there is clearance between the protrusion of the
switching angle and stopper (M4).
If there is no clearance, it means that the switching adjusting plate is pushing the switching shaft excessively, and
this may cause the urethane sheet of the switching shaft to peel off or motor lock.
r With the top cover opened (detection switch in the
ON state), press the speed key and adjust the
clearance between the protrusion of the switching
angle at the left and right frames and stopper (M4) to
0.1 to 0.3 mm (0.004" to 0.012").
Adjusting method
Pressing the “+” speed key increases the correction
value by 1, and moves the folding stopper of folding
plate 2 by 0.125 mm (0.005") in the opposite
direction of the home position.
(The clearance between folding roller 1 and
switching shaft tip widens.)
Pressing the “–” speed key decreases the
correction value by 1, and moves the folding
stopper of folding plate 2 by 0.125 mm (0.005") in
the direction of the home position.
(The clearance between folding roller 1 and
switching shaft tip becomes smaller.)
The settable correction values range from “–20” to
“+5”. The position of the folding stopper ranges
from –2.5 to +0.625 mm (–0.10" to +0.02") with the
home position as 0 mm (0").
t After adjusting the clearance, single fold thick and
thin paper, and check for problems of the folded line.
If the clearance is too narrow, paper jams during
single folding of thick paper, resulting in scratches
and wrinkles near the folded line.
If the clearance is too broad, one folding wrinkle line
occurs near the 15 mm (0.59") position from the
folded line during single folding of thin paper.
