Remove the front cover plate of the sensor by removing the (2) phillips head
screws vertically oriented on the cover.
5.
Visually locate the jumper pin set on the sensor PCB labeled J1.
6.
Turn on your voltmeter.
7.
To adjust the sensor voltage, contact the jumper pins on J1 with the positive and
negative leads from the voltmeter.

If the voltage reads higher than 6 volts, rotate the adjustment screw clockwise in
very small increments until the voltage begins to drop.

position.
9.
If it is difficult to reach the low voltage, clean the sensor lens. It is also possible
that the sensor was too low to begin with, so start at .22 inches away from the
platen.
10.
After setting the voltage, disconnect the voltmeter leads from J1 and move the
carriage about 12 inches to the left and then back to the adjusting position. This
is to ensure sensor height adjustment is maintained after the carriage moves.
