Replacing printheads

Follow these steps to replace the printheads in your printer.
1.Press thePowerbutton to turn on the printer.
2.Open the top cover.
3.Press and hold theResumebutton 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 theResume button again.
The printhead can be damaged if the carriage is not all the way to the left for installation.

5.Lift the handle of a printhead and use it to pull the printhead out of its slot.
6.Shake the new printhead at least six times while the printhead is still in its packaging.

9.Pull the printhead latch all the way forward, and then press down until the latch engages.
