The drum will rotate 218.5 degrees past the second drum position sensor
and then will stop. At this time, the magnetic clutch [A] located behind the
reverse roller [L] and the master feed moter [H] is transmitted to the platen
roller [E] through the belt [G] and the gear/pulley [F]. The platen roller will
then feed the master and press it against the thermal head [K]. Also, the
rotation of the gear/pulley [F] is transmitted to a gear [J] through the relay
gear [I] to drive the upper feed roller [D] and the lower feed roller [C] for
feeding the new master.
When the magnetic clutch [A] turns on, the rotation of the upper feed roller
[D] is transmitted to the reverse roller [L] through the relay gears [B], thus
feeding the master. Also, the master is directed downward towards the
clamper [N] of the drum by the reverse guide [O]. The counter rollers [M] are
used to prevent the leading edge of the master from being wrapped around
the reverse roller [L].
After the master is fed 59.5 millimeters, the magnetic clutch [A] will turn off
and the reverse roller [L] will stop. After the master is fed another 5
millimeters, the master feed clamper solenoid will turn off because the
leading edge of the master has already reached the clamper [N].
