Position The Media Sensor Assembly
Your printer is equipped with a media sensor assembly that detects
the top-of-form position on media with label length indicators (gaps,
notches, holes, or black marks). See page 14.
The media sensor should not be placed in the path of media
features that could cause false gap detection or paper out faults.
Such features are dark pre-printing, rounded die-cut label corners,
vertical gaps associated with side-by-side labels, and extraneous
cut-outs, as shown below.
