Run this test whenever a sensor has malfunctioned or has been replaced.

(3) If a sensor is not operating properly, check its wiring, its connector contact, and the position of the
sensor dog. If everything checks out all right, either the sensor or main board may be defective.
In this case, initialize the NOV-RAM and then run the sensor test again.
(4) As a temporary measure for dealing with a defective sensor, turn off the plotter, set Bit 4 of the DIP
switch to OFF, and then turn the plotter back on.
Note : When the plotter is turned back on, the pen position becomes the plot area's origin (0,0) and the
plotter is not initialized.
