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.
