HP 250 - Routine Maintenance; Electrostatic Paper Hold-Down Surface Cleaning

Graphics Devices
Routine Maintenance
Maintenance of the plotter is limited to a periodic cleaning of
the external surfaces, electrostatic paper hold-down surface, and
air filter.
WARNING
Disconnect the plotter from the power source
prior to performing any maintenance. When
cleaning, apply water using a lint-free tis-
sue. DO NOT allow water to run onto the
electrical components and circuits or
through openings in the enclosure as it may
create a shock hazard. Scratches or punc-
tures in the electrostatic paper hold-down
surface may expose high voltage conductors.
Plotters damaged in this manner should not
be operated.
Electrostatic Paper Hold-Down Surface Cleaning
Dust and other contaminants will lower the paper holding
capability. Although pen ink will not affect hold-down
performance, it may be desirable to remove ink stains as well.
Cleaning moderate contamination can be accomplished as follows:
1. Prepare a mixture of 50% isopropyl alcohol and 50% water
by volume.
2. Apply the alcohol/water mixture to the surface using a
lint-free tissue. Immediately wipe any moisture from the
surface. Never let any liquid stand on the surface as it may
become permanently damaged.
If the surface cannot be easily cleaned with the alcohol/water
mixture, cleaning can be accomplished as follows:
1. Select a clean, lint-free cloth that will not scratch the
surface~
2. Remove transparency ink with solvent (HP 5060-6828) and dry
thoroughly before continuing the cleaning process.
