Adjusting the Media Sensor
When the Stripe printer is powered ON, it performs a self test and configures its
operating characteristics. Some of these characteristics are determined by the position of
the Media Sensor. See Figure 7.
The Media Sensor Assembly consists of two sections. The media passes between a
stationary light source and a movable light sensor. The light source is positioned below
the media, while the light sensor
is positioned above the media.
This adjustment aligns the
position of the light sensor with
the notch or edge of the label.
With the Printhead OPEN, look
through the front of the print
mechanism and locate the Media
Sensor Adjustment Lever.
Reposition the sensor until the
top of the adjustment lever is in
line with the notch in the media.
CLOSE the printhead by moving
the Head Open Lever to the
CLOSED position.
When continuous media (no
notch or opening to sense) is
used, position the Media Sensor
anywhere over the media so that
an “Out-of-Media” condition
will still be sensed.
Non-Continuous Media
This type of media has some type of physical characteristic (web, notch, perforation,
etc.) which indicates the start/end of each label.
The Media Sensor must be properly positioned to sense these indicators. See “Adjusting the
Media Sensor” (above).
Continuous Media
Since continuous media does not contain label start/end indicators, you must tell the
printer via software how long each label is. If you are using ZPL or ZPL II, include a
Label Length (^LL) instruction in each label format you send to the printer (refer to
your ZPL II Programming Guide). If you are using other software to drive your printer,
refer to the instructions provided with that software.
Even with continuous media, you still need to position the Media Sensor in the middle
of the media to sense when you run out of media.
