If your smart labels have no horizontal black bar located wi thin each
liner gap, you must choose between Gap and Advanced G ap
sensing. Run an Auto Calibrate (page 30), then make a Media
Profile printout (page 32). Choose the sensing type that provides
the highest liner gap amplitude compared to the amplitude of th e
antenna line. If you select Gap sensing, and then see th at the
Media Profile printout shows very little amplitude differ ence for the
liner gap compared to the amplitude of the antenna line, selec t
Advanced Gap sensing instead.
Advanced Gap sensing (often called transmissive) uses an L ED
array for the upper sensor and a receiver in the lower sensor to
detect infrared light through the liner gap. This sensing ha s the
advantage of detecting the liner gap as a positive amplitude pulse
and the antenna line as a smaller, negative pulse.
Auto Calibrate
This feature is used to improve the sensitivity and reli ability of the
media sensor in detecting gaps, notches, holes, or black ma rks on
the installed media, as well as a Paper Out condition.
NOTE: You must set the correct Label Length to force Auto
Calibrate to increase media advancement for long la bels
(to detect actual gaps, notches, or marks) and decrease
media advancement for short labels.
To initiate Auto Calibrate, scroll to the Auto Calibrate menu and
press the ↵ key. The printer will advance media the distance
needed to accurately detect the label length indicators , then stop at
the top-of-form position and momentarily display the Sen sed
Distance. This process takes a few seconds and res ults in an
update of the printer values.
Auto Calibrate is completed successfully when the Sen sed
Distance displayed correctly matches that of the ins talled media.
With Gap or Advanced Gap selected, the Sensed Distance sh ould
match the length from the trailing edge of one gap to the trailing
edge of the next gap (one label + one gap). With Mark selected, the
Sensed Distance should match the length from the leading edge of
one black mark to the leading edge of the next black mark.
Auto Calibrate supports label lengths up to 24 inches.
