Adjustable Sensors/Front Fixed Sensor - Tally Dascom 7010 Series Maintenance Manual

1-4. Adjustable Sensors/Front Fixed Sensor

There are two types of media sensors (adjustable sensor located on the rear side of the printer and
front fixed sensor located on the front left) that detect a label or tag position. They are selectable
with the Sensor Select menu ("Rear Adj sensor" for adjustable sensor and "Front Fixed Sen" for
front fixed sensor). By default, the adjustable sensor is selected and it covers wide range of media
width. The front fixed sensor is suitable for printing narrower width media and, since it is located
near the thermal head, more accurate detection of label or tag position will be expected.
Adjustable sensor:
Adjustable sensor consists of two media sensors; the upper sensor (transparent sensor) and the
bottom sensor (reflective sensor). The upper sensor and bottom sensor are used to detect the
labels on the liner or the U-shaped notches of tag. While, the bottom sensor is used to detect the
black marks on tag. Both sensors are used to detect media end.
By turning the adjustable sensor position knob, both transparent and reflective sensors move right
and left simultaneously. As you turn the adjustable sensor position knob, the yellow mark that is
located in front of the scale moves along the scale.
The factory-set position of the sensors is 6.5mm (0.2559") from the media guide. In this position,
the mark is printed on the scale and this position is the same position as the front fixed sensor.
