Printer Operation
1. Check that labels are loaded correctly; labels can
mistakenly be routed above the label guide and sensor
assembly instead of through it. Load labels correctly: see
the loading instructions on the inside cover of the printer,
or refer to the User's Manual .
2. Check that the Media Sensor selection under the
PRINTER CONTROL menu corresponds to the media
installed. In the PRINTER CONTROL menu, set the Media
Sensor to match the media being used. (Refer to the
User's Manual .)
3. Check that the Page Length selected under the PRINTER
CONTROL menu or the Page Length software command
sent by the host computer agrees with the length of the
media installed. (Even though transmissive or reflective
forms are used to establish top-of-form position, a larger
page length will override the gap and skip a page or
pages.) In the PRINTER CONTROL menu, set the Page
Length to match the media being used. (Refer to the
User's Manual .)
4. Check that the printer is optimized to detect the type of
media installed. Perform the Run Calibrate procedure for
transmissive and reflective media. (Refer to the User's
Manual .)
5. Adjust the media sensor horizontally to detect the gap,
holes, notches, or narrow width black stripe. (Refer to the
User's Manual .) If problem persists, replace the media
sensor.
Make sure that the label is not formatted too close to the top
edge of the form. Leave white space equal to eight dot rows at
the top of the label.
