  1. Position the Printhead onto the Locating Pins in the Printhead Assembly. Close Printhead Assembly and secure in the Printhead in place with the Printhead Mounting Screw (do not over-tighten).

  1. Clean the Printhead.
  2. Reload ribbon (if removed), lower the Printhead Assembly, and rotate the Printhead Latchback, into the locked position.
  3. Use the Darkness Adjustment to match the print contrast of the new printhead to that of the old printhead.
