5.9 Replacing the Printhead
If the printhead needs to be replaced, follow the procedure below:
•
Only use a Datamax-O’Neil IntelliSEAQ™ printhead.
• Printheads are fragile; handle with extreme care and never use sharp
objects on the surface.
• If you have questions, contact a qualified technician or Datamax-O’Neil
Technical Support before proceeding.
A. Turn OFF the Power Switch then touch a bare metal printer surface (e.g., the frame)
to discharge any static electricity present on your body.
B. Unplug the printer and open the access cover. If ribbon is installed, remove it.
C. Lower the Printhead Assembly and loosen the Printhead Mounting Screw. (If using an
H-8308X model, loosen both mounting screws.)
D. Carefully raise the Printhead Assembly. Grasp the printhead then disconnect the two
cables and remove the printhead.
E. Position a new printhead under the Printhead Assembly and connect the previously
removed cables.
F.
After ensuring that the printhead cables are not pinched, place the printhead onto
the locating pins under the Printhead Assembly and secure it by tightening the
Printhead Mounting Screw(s). [Do not over-tighten the screw(s)].
G. Using a Cotton Swab moistened (not soaked) with isopropyl alcohol, clean the
printhead then allow it to dry.
