Adjustment Procedure
1
Turn off power at the plotter.
2
Adjust the pen using the pen height gage. (See Pen Holder and Pens ).
3
Install the pen holder in the carriage spindle.
4
Turn on the plotter.
5
Rotate the cam shaft by hand counter-clockwise until the bottom of the
lift fork touches the top of the carriage spindle. See below.
6
Locate the adjustment pad. There should be a gap of .003" to .010"
(about the thickness of a piece of paper) between the pad and the cam
shaft. If not, go to step 12.

If the gap is correct, remove the rear cover (with molded tool rack). Lay
the plotter on its
left side. Remove (2) Phillips head screws from the
bottom edge. Stand the plotter upright. Lift the rear cover straight up.
