Zebra Printer LP2844

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.

Before following the steps in this procedure, open the printer by pulling the release latches forward then lifting the top cover.

2. Grasp the print head spring and pull it to the left; then, slide it free of the latch frame.
