Finisher alignment
This tip provides detailed instructions for aligning the finisher to the printer.
The sides of the finisher must be parallel with the printer and at the same height, or you may have paper feeding 
problems.
There are four locations where adjustments can be made to correctly align the finisher with the printer. There are 
two adjustment casters on the left (the side closest to the printer) and two on the right, underneath the platform 
cover.

Loosen or tighten the wingnuts (G) to adjust the height of the finisher (clockwise raises the finisher).
Step 3: Align the bumper pads
Adjust the two casters on the right side (under the platform cover) to raise or lower the finisher as needed so the

Step 5: Connect the finisher and printer

If the cable folds itself between the finisher and the printer, disconnect the cable, twist it one time, and then 
reconnect it. This may help the cable bend the other direction.
