Ribbon End

Ribbon end detection
The ribbon sensor on the ribbon supply side detects the ribbon end error.
While feeding the media, when the ribbon on the ribbon supply side has not rotated for 15 mm (0.6") or
more, the ribbon sensor will detect the ribbon end error.
Ribbon near end detection
The ribbon near end is detected by the ribbon sensor, from the rotation speed of the supply side ribbon.
This occurs when the remaining ribbon length becomes less than approximately 15 m, 49.2 ft. (ribbon
diameter is approximately 36 mm, 1.4").
Note that the remaining ribbon length (15 m, 49.2 ft.) is a calculated value from the revolution speed of
the ribbon on the supply side. The timing of the ribbon end varies according to the reading condition of
the ribbon sensor and the ribbon thickness.
