Turn off the HP All-in-One by pressing the On button located on the device. 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).

until you have replacement cartridges available to install.
If you are transporting the HP All-in-One make sure you turn off the device by pressing
the On button to power it down properly. Also, make sure you leave the ink cartridges
installed. Doing these actions will prevent ink leaking from the print head assembly.
