4-2 Preventive Maintenance C4705-90000
Moisture on the Plotter/Printer
Users should use the plotter in an environment between 5% and 95% relative humidity. To
recover from moisture condensation, turn the plotter off, and, using the main roller as a
reference, wait until the plotter is completely dry before using it again. (Other environmental
specifications ' chapter 2.)
Noisy Carriage Bushing
To prevent noisy movement of the carriage, remove aluminum or dust particles from the
bushing at the backof 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 Plotter
To maintain the plotter in good operating condition, keep it free of dust accumulation, ink,
and other contamination. Cleaning intervals are determined by the plotter environment and
by the types of plotter supplies used.
Disconnect the plotter from the power source prior
to performing any cleaning. DO NOT allow liquid to
run on to electrical components or circuits, or
through openings in the enclosure, as this can
create a shock hazard leading to death or injury.
