Adjusting the Pinchwheels
Signcutter models 80 cm and wider have pinchwheels with adjustable spring
force*. This allows the user to use maximum force (24 lbs.) for holding vinyl
(which requires more force for better tracking) or less force (8 lbs.) for light-
weight materials like paper and for sandblast resists that must be tracked di-
rectly on the rubber surface. The pinchwheels can also be set in a position that
keeps them completely off the surface so that the inner pinchwheels on larger
cutters will not interfere with pen plotting.
The force adjustment is set by turning a screw on the back of the pinchwheel
assembly.
1. Move the pinchwheel to the access hole on the back of the dust cover.
2. Insert a flat screwdriver into the slot and turn the adjustment screw 90
degrees. When the slot is in the vertical position on the outer wheels the
force is 24 lbs. The horizontal position indicates 8 lbs of force. On units
equipped with inner pinchwheels, force can be set to 12 lbs. (vertical
setting) or 4 lbs. (horizontal setting). The 12 lb. inner pinchwheel setting
is useful for heavier materials such as heavy sandblast or reflective sheet-
ing.

Locking the Pinchwheels Off of the Platen
The idler pinchwheels have a locking feature* that will hold them off of the
platen during cutting or plotting. This will reduce ink smearing if plotting
with a heavy ink marker.
1. Lift the idler pinchwheels off the platen with the pinchwheel lever.
2. Press on the handles at the rear of the idler pinchwheel arm.
3. Flip the locking clip into position with both thumbs. Make sure that the
clip is under the lower tabs.
4. When the pinchwheels are lowered onto the platen the idlers will stay in
the up position.
