Press down and back on the top of the protector to release the cartridge. Slide the
cartridge out of the protector.
Caution: Do not drop the print cartridge. Dropping the print cartridge can
damage it.
10.10 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.
10.11 Printer toolbox
The printer Toolbox contains a number of useful tools to enhance the printer
performance.
Use the printer tools to perform the following tasks:
• Clean the print cartridges
• Align the print cartridges
• Calibrate color
• Print a test page
