Installing the Print Head Unit
The print head unit is the device that projects the ink into the paper. During a print operation, the printer
heats the ink to the boiling point in the nozzle to form a bubble. The bubble expands until there is no
room left in the nozzle for the ink. The printer then ejects the ink onto the paper through the nozzles on
the print head unit.
Make sure the printer is off when you are installing the print head unit and ink cartridges.
It is very important that you install the print head unit correctly. Be sure to follow these steps carefully:
1. Make sure the power cord is attached and the power is off.
2. Open the printer's cover.
Gently press in on the front sides of the printer's cover.
Lift the cover to the open position.
