Storing print cartridges
When print cartridges are removed from the printer, store them in an airtight plastic
container or in the print cartridge protector that comes with the 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 print cartridge. Slide the
print cartridge out of the protector.
Caution Do not drop the print cartridge. Dropping the print cartridge can
damage it.
