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 desiccant until you need to
install them.

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.
