Adjusting the Media Sensor
This adjustment aligns the position of the light sensor with the notch or
edge of the label, so the printer can determine the correct label size.
See Figure 13. With the printhead open, look through the side of the print
mechanism and locate the media sensor adjustment lever (a). Reposition
the sensor until the top of the adjustment lever is in line with the notch or
web in the media or the edge of the label. 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.) that indicates the start/end of each label.
The media sensor must be properly positioned to sense these indicators.
See “Adjusting the Media Sensor” (above). Then, turn on the printer. If the
printer will not auto calibrate, press the MODE button three times, and then
the FEED button once, to manually calibrate (a label will print that shows
the sensor profile).
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 operate your printer, refer to the
instructions provided with that software.
