Note:
Positioning of the paper length and the stoppers of
Table 1 and 2
(Example) In the case of performing the zigzag fold
using sheets of paper 12" in length:
Table 1 = 12" x (2 / 3) = 8"
Table 2 = 12" x (1 / 3) = 4"
Test folding:
If the Test key is pressed, two sheets will be folded
while not affecting the indication of the counter.
Check the folding alignment with the second sheet
folded.
If the fold is skewed, refer to the skew adjustment
section on page 19 and 20.
Caution:
If the fold stopper fine adjustment knob is moved,
when the Test key is pressed, the machine will
continue to fold. When the Start/Stop key is pressed,
the machine will start to fold after the stopper is
returned to the previous position.
