• Do not remove the plastic tape covering the ink nozzles until you are ready to
install the print cartridge in the printer. If the plastic tape has been removed
from the print cartridge, do not attempt to reattach it. Reattaching the tape
damages the print cartridge.
10.9 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, 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 that has been 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.
