Replacing the Print Head
In the event you need to replace the print head, read the procedure and
review the removal and installation steps before actually replacing the print
head.
Prepare your work area by protecting against static discharge. Your work
area must be static-safe and include a properly grounded conductive
cushioned mat to hold the printer and a conductive wrist strap for yourself.
NOTE: Turn the printer power off and unplug the power cord before
replacing the print head.
