4.7.6 Ribbon Tension Roller
The ribbon tension roller is used to help maintain a constant tension on the ribbon.
The roller is mounted on a linear slide on the cassette, the end of the shaft is
dome shaped and does not rotate.
When the cassette is interlocked with the printer body the end of the shaft comes
into contact with the tension sensor.
As the ribbon tension increases the pressure that is applied to the sensor also
increases. The data from this sensor is then analysed by the processor and the
stepper motors are adjusted accordingly.
