1.Press the Power button to turn on the printer.
2.Open the top cover.
3.Press and hold the Resume button until the carriage moves to the left.

CAUTION:

Be careful not to proceed until the carriage is on the left side of the printer.
If the carriage does not move to the left automatically, turn the printer off and back on and then try holding down the Resume button again.
The printhead can be damaged if the carriage is not all the way to the left for installation.
