Maintain 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, or dried
ink from the exterior of the printer, use a soft cloth moistened with water.
When cleaning the 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. If a household cleaner or detergent
has been used on the printer, wipe the 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.
