1.3.4. Paper Width (PW) Sensor Operation
The PW sensor is mounted on the ribbon mask holder to measure the paper width and detect the top
edge of the paper. However, in cases where print data is over the paper width, the image cut function
does not operate in all modes. This section describes when the image cut function is operational, as
shown in the following table.

The measured paper width value is used to estimate the printhead centering position.
When narrow continuous paper (fewer than 30 columns) is loaded, the printer changes the
centering position to the proper position, based on the measured paper width.
