Preventive Maintenance

 Moisture on the Printer

Users should use the Printer in an environment between 20% and

80% relative humidity. To recover from moisture condensation, turn

the Printer Off, and, using the main roller as a reference, wait until

the Printer is completely dry before using it again.

 Noisy Carriage Bushing

To prevent noisy movement of the carriage, remove aluminum or

dust particles from the bushing at the back of the carriage, and from

the slider path along which the bushing moves.

Belt Swelling

To prevent new belts from swelling incorrectly, keep them in their

bags with dissicant until you need to install them.

Cleaning the Printer

To maintain the Printer in good operating condition, keep it free of

dust accumulation, ink, and other contamination. Cleaning intervals

are determined by the Printer environment and by the types of

Printer supplies used.

General Cleaning

Proper general cleaning should include the following:

1   Blow away dust accumulation with compressed air if available.

2   Clean the outer surface of the Printer with a damp sponge or cloth.

Use a mild soap and water solution if necessary. Do not use abrasive

cleaners.

3   Wipe the Printer dry with a soft lint-free cloth.
