UNIT OPEN SWITCH AND GUIDE OPEN SENSOR

The guide open sensor is ON while the DF guide is open, and the unit open switch
is ON when the DF unit itself is raised. The machine will not carry out scanning
when either of these is ON, but will instead display a message instructing the user
to close the DF.
