Av Label Print Start Position Detector Mechanism - Brother PT-9600 Service Manual

2.1.9 AV Label Print Start Position Detector Mechanism (PT-9600/PT-3600 U.S.A.)
This mechanism makes it possible to print at the proper position on Avery (AV) labels half-cut
in a 24-mm-width AV labels tape.
As shown below, it uses a reflection photosensor named AV print position sensor (AV sensor
PCB ASSY). When a black detection mark (lower mark) printed on the back of an AV labels
tape comes to the AV print position sensor, the sensor receives no reflected light, signaling the
print start position.
(1) Pressing the "Print" key will start tape feeding.
(2) When a lower black detection mark on the back of an AV labels tape comes to the AV print
position sensor, printing will start.
(3) When the printed label exits from the tape cutter position, tape feeding will stop. The AV
labels tape will be automatically cut off.
(1) Start tape feeding
(2) Start printing
(3) Stop printing and cut tape
