0016-8203
When the roll media sensor detects media loaded with the printer powered, the roll media pick-up roller touches
the media to rotate the roll media feed roller, thus feeding the roll media onto the platen. Roll media feeding is
controlled by the roll motor and roll feed unit PCB.
The roll media pick-up roller is moved up and down by the cam, and the cam movement is detected by the roll
media cam sensor.
When the printer is turned on with roll media loaded, the roll media pick-up operation starts automatically.
F-2-23
If the roll media sensor detects that there is no roll during roll media pick-up operation, the roll media is ejected.
