6.7.2. Print Cartridges
This printer uses consumer replaceable print cartridges.
Warning:
Print cartridge ink contains chemical substances, which may be harmful if swallowed. Keep new and
used cartridges out of reach of children.
Caution:
Do not use refilled print cartridges. Attempting to refill a print cartridge can cause a sudden drainage
and/or leakage of ink, which can damage the product and possibly personal property.
6.7.2.1. Print Cartridge Care
1. Keep unused print cartridges sealed in their original packaging. When replacing a print cartridge,
install the new cartridge promptly.
2. Do not turn the product off with the print cartridge out of the service station (left end of the carriage
path). The service station cap seals the print cartridge nozzles from exposure to air, to minimize the
formation of dried ink in the nozzles.
3. Do not allow the print cartridge contacts and nozzles to touch any surface or object, including your fin-
gers. Skin oil and dust can cause print quality or missing dots problems.
4. Store print cartridges at room temperature.
6.7.2.2. Print Cartridge Expiration
Using print cartridges that are past their expiration date can cause print quality problems. The print cartridge
life specification is shown in the following table:

All Cartridges
The open life specification of the cartridge is valid for use in an office environment, with a printing frequency
of at least once a month.
To determine if a print cartridge is past its expiration date, read the use before date printed on the box and
ensure the print cartridge is sealed in its original packaging. The print cartridge should be installed before
the date shown on the package (see Figure 6.11.5).
