goes off. (You’ll hear the cartridge cradle return to its home
position on the right side of the printer.)
7 If the Resume light continues to blink after you install new
print cartridges, check the part numbers on the cartridges to
ensure you installed the correct ones.
Storing print cartridges
To maintain excellent print quality from your print cartridges:
• Keep all print cartridges in their sealed packages, at room
temperature (60-78 degrees F or 15.6-26.6 degrees C), until
you are ready to use them.
• Once installed, leave the print cartridges in their cradle at all
times to keep them from drying out or becoming clogged.
• Store unsealed print cartridges in an airtight plastic container.
• Do not unplug the printer until printing is complete and the
print cartridge cradle has returned to its home position on the
right side of the printer. The print cartridges will dry out if not
stored in their home position.
• Turn off the printer and allow the print cartridges to return to
the right side of the printer for proper capping of the nozzles
before unplugging the power cord or turning off any
attached power strip.
