8. Recheck the clamp height in case tightening the linkage moved it out of adjustment. If the
clamp has moved out of adjustment, repeat steps 3 through 7 as necessary.
9. Once a satisfactory setting has been obtained, replace all covers and unlock the power
source.
Figure 31
Clamp Leveling Procedure:
Remove the knife, false clamp plate and the cut stick. Place a 2” wide strip of paper under the left and
right hand side of the clamp. Access the Knife Adjust menu in the “Maintenance Section” and cycle
the clamp and knife to the down position. Pull on the paper strips; if one pulls out, that side will have
to be adjusted. NOTE: Keep the adjustments small so the clamp will remain at 4”
1. Turn the machine off and lock out the power. (See page 6)
2. Remove the bottom front cover and the top rear cover.
3. Loosen one end of the rack and pinion shaft coupling (pg. 50, fig. 30)
4. Loosen the clamp rod bottom nut on the side of the clamp that doesn’t hold paper.
5. Adjust the top clamp rod nut until the paper is held tight.
6. Tighten the bottom nut, then recheck the paper. Readjust if necessary.
7. Tighten the rack and pinion shaft coupling.
8.7.4 Proximity Switches
Proximity switches are used to inform the computer of the up and down positions of the knife and
clamp. They do not determine the stopping positions of the knife and clamp, and therefore rarely
need to be adjusted. However, if a proximity switch is not sensing the knife or clamp position
correctly, it may need adjustment.
To check if the four proximity switches are sensing correctly, go to Maintenance Mode (page 26) and
select Diagnostic. Then select Sensor Data, and a list of abbreviations for several inputs and outputs
