Adjusting the Movable Sensor for Web (Gap) Sensing
The movable sensor supports the web/gap positions used by the legacy Zebra® desktop printer
models and for some non standard media configurations. Printer’s with typical web (gap)
sensing in the fixed center position or the movable sensor’s set to the default position are offset
from the center of the printer to allow for gap sensing of labels that are side by side on a roll -
see below.
Web (Gap) sensing with the movable sensor can only function when the sensor’s alignment
arrow points to any position on the alignment key. The sensor must be aligned with the labels
(or other media) to sense the gap between the labels. The example above shows where the
sensor is set if center aligned positioning is used. It will miss sensing labels with a 2-up label
configuration and with the sensor in the ‘default’ position, it will be able to the detect labels
and the gaps between them.
