3-6. TIMING FOR BAR CODE DETECTION

1. With ribbon cassette and paper feed tray with the paper are inserted, the time when power

switch is turned on.

2. Power is turned on except above condition, after that, ribbon cassette and paper feed tray are

inserted.

3. Once ribbon cassette is removed,  and when it is inserted again.

Operation of bar code detection

1. Paper feed lever is moved to printing position.

2. Paper feed roller is rotated reversely, bar code ring is rotated by engaging bar code detection

gear.

3. Bar code sensor detects the bar code.
