Magenta cartridge low The print cartridge is nearing the estimated
end of its useful life.
The product indicates when the print
cartridge level is low. The actual print
cartridge life remaining can vary. Consider
having a replacement cartridge available to
install when the print quality is no longer
acceptable. The print cartridge does not
need to be replaced now.
Magenta cartridge very low The print cartridge is at the estimated end of
its useful life.
Print quality might decrease. Replace the
print cartridge when the print quality
becomes unacceptable.
To ensure optimal print quality, HP
recommends replacing the print cartridge at
this point. You do not need to replace the
print cartridge at this time unless the print
quality is no longer acceptable. The actual
print cartridge life can vary.
Once an HP print cartridge has reached the
very low threshold, the HP Premium
Protection Warranty on that print cartridge
has ended. All print defects or print cartridge
failures incurred when an HP print cartridge
is used in “continue in very low” mode will
not be considered to be defects in materials
or workmanship in the print cartridge under
the HP Print Cartridge Warranty Statement.

Replace fuser kit
This alert appears only if the product is
configured to stop when the print cartridge
reaches the very low threshold. The product
indicates when a supply level is at its
estimated end of life. The actual life
remaining might be different than the
estimation. Have a replacement supply
available to install when print quality is no
longer acceptable. The supply does not
need to be replaced now unless the print
quality is no longer acceptable. After an HP
supply has reached its approximated end of
life, the HP Premium Protection Warranty
on that supply ends.
The product indicates when the fuser kit is
at its estimated end of life. The actual life
remaining might be different than the
estimation. Have a replacement fuser kit
available to install when print quality is no
longer acceptable. The fuser kit does not
need to be replaced now unless the print
quality is no longer acceptable. After the
fuser kit reaches its approximated end of
life, the HP Premium Protection Warranty
on that fuser kit ends.
Replace the specified color cartridge.
Or, configure the product to continue
printing by using the Manage Supplies
menu.
CAUTION: The fuser can be hot while the
product is in use. Wait for the fuser to cool
before handling it.
1. Open the right door.
2. Grasp the blue handles on both sides
of the fuser and pull straight out to
remove it.
