Caution If the paper tears when you are removing it from the rollers, check the rollers

likely to occur.

Information on ink cartridges
The following tips help maintain HP ink cartridges and ensure consistent print quality.
● Keep all ink cartridges in the original sealed packages until they are needed.
● Turn off the HP All-in-One from the control panel. Do not turn off the device by turning off a
power strip or unplugging the power cord from the HP All-in-One. If you improperly turn off the
HP All-in-One, the print head assembly might not return to the correct position.
● Store ink cartridges at room temperature (15.6°-26.6° C or 60°-78° F).
● HP recommends that you do not remove the ink cartridges from the HP All-in-One until you
have replacement cartridges available to install. If you are transporting the HP All-in-One make
sure you leave the ink cartridges installed to avoid ink leakage from the print head assembly.
● Clean the print head when you notice a significant decrease in print quality.
● Do not clean the print head unnecessarily. This wastes ink and shortens the life of the
cartridges.
● Handle ink cartridges carefully. Dropping, jarring, or rough handling during installation can
cause temporary printing problems.
If you are experiencing problems with printing, you might have a problem with one of the print
cartridges.
