maintaining the printer body
Because the printer ejects ink onto the paper in a fine mist, ink smudges will
eventually appear on the printer case and adjacent surfaces. To remove smudges,
stains, and/or dried ink from the exterior of the printer, use a soft cloth moistened
with water.
When cleaning your printer, keep these tips in mind:
●
Do not clean the interior of the printer. Keep all fluids away from the
interior.
●
Do not use household cleaners or detergent. In the event that a
household cleaner or detergent is used on the printer, wipe the
printer's exterior surfaces with a soft cloth moistened with water.
●
Do not lubricate the support rod that the print cartridge cradle uses
to slide back and forth. Noise is normal when the cradle moves back
and forth.
