5. Before transporting the printer, secure the rear tray in the closed position with tape. Otherwise, the
tray could open and perhaps break and fall out of the printer.
If you need to leave the printer turned off for a long time, follow the additional steps below.
1. Turn off the power using the Power key on the front panel.
2. Also turn off the power switch at the rear of the printer.
3. Disconnect the printer's power cable.
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 printheads. Preparing the printheads normally takes just over a minute. However, if the
printer has been off for a six weeks or more, preparing the printheads could take up to an hour.
If the printer remains off for a long period of time, the printheads may become unusable. In this case,
you need to replace the printheads with new ones.
