Refer to Figure 5.2 while performing the following procedure.
CAUTION
Observe proper Electrostatic Safety Precautions when removing,
handling and replacing the Printhead.
1. Turn the printer OFF and remove the Power Cord.
2. Open the Printhead Assembly and remove the media and ribbon; then close
the Printhead Assembly.
3. Properly connect yourself to an anti-static protection system.
4. Locate the Spring-loaded Printhead Mounting Screw on top of the Printhead Assembly.
5. Loosen the Mounting Screw until it disengages from the Printhead.
CAUTION
Use care to minimize any physical damage to the
Printhead during the remainder of this procedure.
6. Slowly open the Printhead Assembly. The Printhead will be resting on the

to release the Data Cables.

down on the Power Cable Locking Tab.

Power Cable and remove the Printhead through the front of the printer.

on the label located under the new printhead.
11. Connect the Printhead Power Cable to the appropriate connector.
12. Spread apart the holding tabs on the sides of the two data connectors and
press the appropriate Printhead Data Cable into each connector. The
Holding Tabs must “snap” into place around the cable connectors. Dress
cables completely behind the printhead.
13. Carefully position the alignment slots in the new Printhead over the
alignment posts on the underside of the mounting bracket (refer to
Figure 5.2).
14. After ensuring that no cables are between the Printhead and the Printhead
Bracket and verifying the Printhead is seated properly, carefully tighten the
mounting screw. (If any problems occur during this installation process, contact
