To replace a damaged printhead, follow the procedure below.

Printheads are fragile; use extreme care when handling and never use a sharp object on the
surface. If you have questions, contact a qualified technician or Datamax-O’Neil
Technical
Support before proceeding.
1. Touch a bare metal part of the printer’s frame to discharge any static electricity that may be
present on your body.
2. Turn ‘Off’ and unplug the printer. Open the cover; if ribbon is installed, remove it.
3. With the printhead locked in the down position, loosen the Printhead Mounting Screw (it will
remain in the assembly).
4. Unlatch the Printhead Assembly. While holding the Printhead, raise the assembly. Disconnect
the two cables and then remove the old Printhead.
5. While carefully holding the new Printhead, connect both cables.
6. Position the Printhead onto the Locating Pins in the Printhead Assembly and secure in place
with the Printhead Mounting Screw (do not over-tighten).
7. Clean the Printhead (see Section 5.2).
8. Reload ribbon (if removed), lower the printhead assembly, and rotate the printhead latch
back, into the locked position.
9. Use the Darkness Adjustment to match the print contrast of the new printhead to that of the
old printhead see Section 5.7.
