Printer Maintenance Tips
Because the printer ejects ink onto the paper in a fine mist, ink
smudges will eventually appear on the printer case. Follow the
cleaning instructions provided below.
• Do not clean the interior of the printer. Keep all fluids away from
the interior.
• To remove stains, smudges and/or dried ink from the exterior of
the printer, use a soft cloth moistened with water. 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 rod on which the print cartridge cradle
moves. Noise is normal when the cradles move back and forth.
For information on cleaning print cartridges and the print cartridge
cradle, see “Manually Cleaning the Print Cartridges and Print
Cartridge Cradle” on page 40
For maximum performance and reliability, the
printer should be handled and stored in an upright,
level position.
Do not tip your printer after heavy usage. If the printer is tipped
soon after heavy printing, it is possible for excess ink to spill. Clean
up spilled ink using the methods previously listed in this section.
