Printhead Pressure Block Adjustments

These adjustments to the left and right pressure blocks are typically made
when the print quality is not even across the surface of the label, and may be
necessary when replacing the printhead.
NOTE: Make no changes or adjustments while the SLPA is in operation.
Left Pressure Block
Manually adjust the left pressure block so its handle is aligned with the bold
mark on the pressure block adjustment scale.
Right Pressure Blocks
Use the lead screw knob to position the right pressure block with its pointer
near the right edge of the media in use.

Positioning The Media Sensors

The SLPA is equipped with upper and lower media sensors that detect the
top-of-form position on media with label length indicators (black marks, gaps,
notches, or holes). These media sensors also detect Paper Out conditions.
Use the handles on the lower media sensor to horizontally position it so that
the left edge of the sensor's visible red LED is aligned under the left edge of
the adhesive label of the installed media.
