Table 7-1 Supplies status messages (continued)
Control panel message Description Recommended action
Replace toner collection unit The product indicates when a toner
collection unit is at its estimated end of life.
The actual life remaining might be different
than the estimation. Have a replacement
toner collection unit available to install when
print quality is no longer acceptable. The
toner collection unit does not need to be
replaced now unless the print quality is no
longer acceptable. After a toner collection
unit has reached its approximated end of
life, HP’s premium Protection Warranty on
that toner collection unit ends. Replace the toner collection unit.
If you wish to have the toner collection unit
operate past its estimated capacity,
configure the product to continue printing by
using the
Manage Supplies menu. This is not
a recommended option because of the risk of
overfilling the toner collection unit, which
could result in the need to service the
product.
Replace transfer kit The product indicates when a transfer kit is
at its estimated end of life. The actual life
remaining might be different than the
estimation. Have a replacement transfer kit
available to install when print quality is no
longer acceptable. The transfer kit does not
need to be replaced now unless the print
quality is no longer acceptable. After a
transfer kit has reached its approximated
end of life, HP’s premium Protection
Warranty on that transfer kit ends. Replace the transfer kit. Instructions are
included with the transfer kit.
Supplies in wrong position Two or more print-cartridge slots contain the
wrong color print cartridge.
From left to right, the print cartridges should
be installed in this order:
● Yellow
● Magenta
● Cyan
● Black
Install the correct color cartridge in each slot.
Supplies low This message appears when at least two
supplies have reached the low threshold. The
actual supply life remaining might vary.
Touch the
Supplies button to see which
supplies are low. You do not need to replace
the supplies at this time unless print quality is
no longer acceptable. After an HP supply
has reached the very low threshold, the HP
premium protection warranty for that supply
has ended.
To continue printing in color, either replace
the supply or reconfigure the product by
using the
Manage Supplies menu on the
control panel.
