5.4 Printhead Pressure Adjustment

To accommodate a variety of media types, the pressure applied by the printhead assembly is adjustable. This pressure is factory set to work with most media types, so this adjustment should only be performed after attempting to improve print quality through the use of the (1) heat and/or (2) print speed. When adjusting, use only the minimum pressure necessary for better imaging. To adjust:

1.Load at least 4” (102mm) wide media and ribbon, see Section 3.2.

2.Ensure the Media Width Adjustment is set to its “left most” position, see Section 5.2.

3.Press the FEED + CANCEL buttons simultaneously to print a ‘Configuration/Dot Check’ test label.

4.Turn the Printhead Pressure Adjustment Screws counterclockwise to increase the applied pressure or clockwise to decrease it. Make equal adjustments to each screw to achieve even print contrast across the media.

;Note: When using narrow media it is sometimes necessary to increase the pressure on the inner (closest to centerplate) Printhead Pressure Adjustment Screw to prevent ribbon smudging.

;Note: Excessive pressure can reduce the service life of the printhead and platen roller.

Unequal pressure may cause ribbon and label tracking problems.
