Positioning the Media Sensors
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). These sensors also detect when a Paper Out
condition exists.
See page 221 for media and label length indicators.
The media sensors 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.
