Drum End Play Adjustment
Symptoms
♦
Text cut in NORMAL mode has closure problems.
♦
Y axis backlash check procedure shows no problem.
Objective
To slide the plotter drum and X Axis gear toward each other and clamp them in
position to remove end play; to make sure the drum still rotates without binding.
Adjustment Procedure
1
Turn the plotter power off.
2
Remove all tools and material from the plotter.
3
Open the bail arms to free drum.
4
There should be end play of about
.003 to .005 inch. This play exists
because the ball bearing has a
flexible race.
If the amount of play does not exceed
.005 inch and all check procedures in
this section have failed to reveal the
cause of the plotter's symptoms, contact
Gerber Field Service Department at
800-828-5406, or fax at 860-871-3862.
5
If there is more than .003 to .005 inch
of play, remove the front cover. Lay
the GSx
plus
on its left side and remove the (2) Phillips head screws on the
bottom edge closest to the front of the plotter. Then stand the plotter
upright.
CAUTION: Do not rest the plotter on its right side. Do not use the
way shaft to lift or turn the plotter.
6
Pull the front cover upwards and, at the same time, pull one side away
from the plotter frame.
Be careful not to lift the cover so high that the front
panel cable disconnects. Pivot the cover to the side of the plotter.
