Keep the used Maintenance Cartridge level as you put it in the plastic bag. Expel excess air
from the plastic bag and seal the zipper.

Confirm the Maintenance Cartridge is right-side up, put it in the box with the packaging
material attached, and store it so that it stays level.
Used maintenance cartridges are heavy. Always grasp the cartridge
firmly and keep the cartridge level during removal and storage. If you
drop a used Maintenance Cartridge or store it at an angle, ink may leak
and cause stains.
The remaining Maintenance Cartridge capacity is recorded on each
printer. Do not install a used Maintenance Cartridge in another printer.
