Using the Movable Black Mark Sensor
The movable black mark sensor allows the printer to use media with black marks or notches
(holes) on the back side of the media (or media liner) that are not located in the center of the
media.
The movable sensor’s second functional feature is adjustable transmissive web (gap) sensing
to positions that match legacy Zebra
®
desktop printer sensor locations and in between. This
provides for use of some non standard media variations or irregularly shaped media.
The movable black mark sensor can not properly sense continuous media or labels (for inter-
label gap sensing) if the sensor is not in the default sensing area for web (gap) sensing. See
