HP Deskjet 6540 Color Inkjet Printer - Manual (Page 127)

Storing print cartridges
When print cartridges are removed from the printer, store them in a print cartridge
protector or an airtight plastic container.
A print cartridge protector comes with the photo print cartridge and the gray photo
print cartridge. If you store the print cartridge in an airtight plastic container, make
sure that the ink nozzles face down but are not in contact with the container.
Inserting the print cartridge into the print cartridge protector
Slide the print cartridge at a slight angle into the protector, and snap it securely in
place.
Removing the print cartridge from the print cartridge protector
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.
14.11 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.
