Pack and Ship Your Machine
When you transport the machine, use the packing materials that came with your machine. Do not tip or turn
the product upside down. If you do not pack the machine correctly, any damage that may occur in transit may
not be covered by your warranty.
The machine should be adequately insured with the carrier.
IMPORTANT
It is important to allow the machine to “park” the print head after a print job. Listen carefully to the machine
before unplugging it to make sure that all mechanical noises have stopped. Not allowing the machine to finish
this parking process may lead to print problems and possible damage to the print head.
1. Unplug the machine from the electrical socket.
2. Using both hands, use the finger holds on each side of the machine to lift the scanner cover into the open
position. Then unplug the machine from the telephone wall socket and take the telephone line cord out of the
machine.
3. Unplug the interface cable from the machine, if it is connected.
4. Remove the orange protective part from its storage place inside the machine.
5. Gently close the scanner cover using the finger holds on each side.
6. Open the ink cartridge cover.
7. Press the ink release levers to release the ink cartridges and then take out the ink cartridges.
