4Ć4 Preventive Maintenance C4699Ć90000
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 fromthe 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.
