Printhead Pressure Adjustment
Using lower Printhead Pressure and Darkness settings can extend Printhead life. If printing is too light on one side, or if thick media is used, Printhead Pressure may require adjustment.
The Zebra 170PAX Series printers have two toggles. These toggles are typically positioned at the 1/4 and 3/4 positions across the width when using full width media. When using narrow media the outer toggle should be reduced to allow the inner toggle to have maximum effect.

To increase Printhead Pressure, loosen the Upper Knurled Nut on the Toggle and adjust the Lower Toggle Adjusting Nut downwards.
To decrease Printhead Pressure, loosen the Upper Knurled Nut and adjust the Lower Toggle Adjusting Nut upwards.
Adjust Printhead Pressure for optimum print quality.
To lock the toggle pressure, tighten the Upper Knurled Nut against the Lower Toggle Adjusting Nut.
Enter the configuration mode and set the Darkness to the optimum level for the installed media.
