Move or store the printer
If you need to move or store the printer, prepare it correctly to avoid possible damage to it. To prepare
the printer, follow the instructions below.
1. Do not remove the ink cartridges or printhead.
2. Make sure that no paper is loaded.
3. Turn off the power using the Power key on the front panel.
4. Unplug the printer's power cord.
5. Disconnect any cables connecting the printer to a network or a computer.
CAUTION: If you turn the printer upside down, ink could escape into the printer and cause serious
damage.
When the printer is turned back on, it takes about three minutes to initialize itself and to check and
prepare the printhead. Preparing the printhead normally takes just over a minute. However, if the
printer has been off for a six weeks or more, preparing the printhead could take up to 45 minutes.
CAUTION: If the printer remains off for a long period of time, the printhead may become unusable.
In this case, you need to replace the printhead with a new one.
TIP: Because preparing and purging the printhead uses both time and ink, you are strongly
recommended to leave the printer always on or in sleep mode, whenever possible, to maintain the
health of the printhead. In both cases, the printer wakes up from time to time to maintain the printhead.
Thus you can avoid going through lengthy preparation processes before using your printer.
