PROBLEM DESCRIPTION: ImageWriter 15" prints OK but the carriage
seems to make a grinding sound when moving across the print bar.
This often happens after the carriage motor has been replaced.
CAUSE: The screws mounting the carrier motor on its grommets may
be too tight causing vibration (grinding noise).
CURE:
1. Loosen the screws that secure the Carrier Motor Clamps.
2. Loosen the four screws that secure the Carrier Motor to the bottom
cover of the printer.
3. Cross tighten the four Carrier Motor Screws until you feel some
resistence but DO NOT over tighten. If the Carrier Motor has just
been replaced and the screws have been over tightened, you may
have to replace all eight Carrier Motor Rubber Grommets and cross
tighten again. Remember, tightening the screws to much will cause
the grommets to over compress and cause a vibration that exhibits
the grinding sound.
4. Tighten the screws that hold the Carrier Motor Clamps.
5. Run Self Test to check for the vibration problem.
Note: You may have to follow the above proceedure several times
before the noise is eliminated.
If the above cure doesn't fix the problem, search on GTS and the
product's name to obtain a general troubleshooting procedure.
