Maintaining Printer
Cleaning Printer
Since dust, paper fibers, and ink
particles will collect on the printer,

you should clean it as described in
the following paragraphs.
When cleaning, do not drop or
spray any cleaner directly into the
printer.

Cleaner
Use isopropyl alcohol or a noncaustic liquid household cleaner that
does not damage plastic materials.

Procedure
Make sure printer power is OFF.
Remove access cover, pull

and raise column indicator.

Press platen release levers all
the way down, and lift platen

up and away from printer.

Platen Release Levers

Do not stand the platen upright

on one of its knobs. And do
not scratch the platen surface.

Moisten soft cloth with platen
cleaner, and use this cloth to
clean rubber surfaces of platen
and cradle rollers.
Discard cloth and set platen
aside to dry.

Moisten another soft cloth or
cotton swab with noncaustic

household cleaner (not platen
cleaner), and use this cloth or
swab to clean card guide and
cradle.

Air dry all cleaned surfaces.

Reinstall platen and access
cover.

Dos and Don’ts
Office Area
To help you maintain the proper
operating temperatures, keep your
printer away from sources of

extreme temperature such as direct
sunlight, room heaters, and air
conditioners.

And keep paper clips, coffee,

matches, cold drinks, and other
small objects and liquids away from
the printer. If they fall inside they
will cause damage.

Prinfwheels and Ribbon
Cartridges
Keep samples of your early print-

outs, using cloth and film ribbons,

so you will know when to replace
the printwheel and ribbon cartridge.

To get more out of your printwheels

and ribbon cartridges, use cloth ribbon for preliminary drafts and film
ribbon for final copies.
