Adjusting the Printhead Pressure

You may need to adjust printhead pressure if printing is too light on one side, if you use thick media, or if the media drifts from side to side during printing. Use the lowest printhead pressure necessary to produce good print quality.

The printhead pressure adjustment dials have setting marks from 1 to 4 in half-mark increments.

1	Inside dial
2	Outside dial

Begin with the following pressure settings based on your media width, and then make adjustments if necessary.

Starting Points for Printhead Pressure
Media Width	Inside Dial Setting	Outside Dial Setting
≥ 89 mm (≥ 3.5 in.)	2	2
76 mm (3 in.)	2.5	1.5
51 mm (2 in.)	3	1
25 mm (1 in.	4	1
