Print Head Installation Guide (Zebra 105SL ™ )


The Zebra 105SL Printhead is sensitive to static electricity, which can damage the printhead or reduce its life. Ground yourself by touching some metal, such as printer’s metal base, before touching the printhead.

1. Clean the printhead to remove any salt or oil left from handling prior to operation.


2. Turn power switch off and open media compartment door.”.

3. Open the printer by moving printhead locking handle to the “Open Position”.

4. With one hand supporting the printhead, remove the printhead from the printhead-mounting bracket by unscrewing the retention screw in the top center of the mounting bracket.

5. Disconnect, in order, the printer data cable (wide) and power cable (narrow).

6. Connect the printer cables to the new printhead, first power and then data.

7. Attach the new printhead onto the printhead mounting bracket by aligning the mounting hole. First align the left side, then the right. Two audible “clicks” or “snaps” may be heard when the head is properly aligned,

8. Tighten the retention screw in the top center of the printhead mounting bracket. This should be self centering.

9. Align the printing stock and thermal transfer ribbon and close the printhead locking handle.

10. Align the spring loaded tension bar/bars as needed for optimal print quality.

11. Note: as an addition aid in aligning the printhead, it may be helpful to mark where the old printhead was with a felt tip pen, before removing.


NOTE: Normally, mechanical adjustment is not necessary when replacing the printhead. Mounting screws on the mount assembly automatically locate the printhead. However, if the new print head performs poorly, some adjustment may be necessary.
