Adjustment procedure
1) Make a mark on the end surface of the drum
flange, in a position 200 forward (in the direction
of the forward end) from the rear end of the
drum's opening.
2) With the press roll activated, turn the main
motor shaft by hand, and stop turning when the
press roll starts to descend (move in the direction
of the arrow).
Standard value
¡Open the front cover, and check whether the cen-
ter of the press roll is aligned with the mark
made in step 1).
NOTE
Standard valueItem
Alignment of mark on flange
end and center of press roll
±2mm
If the alignment is not correct:
1) Loosen the 2 hex bolts indicated.
2) Loosen the adjustment collar (eccentric) fixing
screw.
3) Turn the adjustment collar (eccentric) to move
the flange and adjust the alignment.
Moving the flange upward makes turning off of
the press occur later \ thereby making the
printing range longer
Moving the flange downward makes turning off
of the press occur earlier \ thereby making the
printing range shorter
