Printing Basics: Printer Maintenance Tips
Printer Maintenance Tips
Because the printer ejects ink onto the paper in a fine mist, ink
smudges will eventually appear on the printer case. 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 print cartridge support rod. Noise is normal
when the print cartridge cradles slide back and forth.
For information on cleaning print cartridges and the print cartridge
cradle, see page 46.
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.
