When you insert a supply into the device, the device will inform you if the supply is not a
genuine HP supply. If you insert a genuine HP supply that has reached the low state from
another HP device, the device identifies the supply as non-HP. Simply return the supply to
the original device to reactivate the HP features and functionality.
Resetting the printer for non-HP supplies

Unauthorized message . In order to print with this supply, you must press E
NTER the first
time you install this non-HP supply.
CAUTION
The device will not stop printing when this type of supply is empty. Printer damage could
occur if the device prints with an empty non-HP print cartridge or imaging drum. See

Packard limited warranty statement and Print Cartridge and Imaging Drum Limited Warranty
Statement.
