Plotter Adjustments 67

7. If the X motor pinion remains stationary (i.e., if there is

backlash), locate the X motor mounting screws (Phillips head

screws) which hold the X motor against the motor bracket on

the side plate. Loosen these screws.

Apply light pressure to the motor to tighten the mesh of the X

axis gear and the X motor pinion.

CAUTION: Forcing the X axis gear and X motor pinion to

mesh too tightly can cause the X axis gear to wear

prematurely.

If you adjust the mesh too loosely, poor letter quality will

result. However, it is safer to tighten the mesh gradually,

cut a test plot, then tighten again rather than adjust the

mesh too tightly.

9. While applying pressure, tighten the four screws.

10. Replace the plotter cover and turn on power at the plotter.

11. Load vinyl in the plotter and install the knife holder. Select

AXIS SWAP mode and cut a test plot.

12. If symptoms persist, repeat the Adjustment Procedure.
