Moveable Blackline Sensor Option
The factory installed moveable blackline sensor option 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 moveable 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 moveable blackline 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
Adjusting the Moveable Sensor for Web (Gap) Sensing on page 52
