The infrared mug/cup sensor can sense the presence of a mug or cup without using moving parts.

The sensor is equipped with an indicator light.  This light will help you get the best results from the 
infrared mug/cup sensor.

Under these conditions:

•

Machine door open

•

Cup station in place

•

No cup in the station

The indicator light should be off.  If it is on, it is indicating improper cup station alignment or excessive 
sensor sensitivity.

Under these conditions:

•

Machine door closed

•

Cup station in place

•

No cup in the station

Press any letter on the selection switch panel, for example, A.  Only the letter A should be showing in 
the message display.  If “

” is displayed, it indicates one or more of the following:

•

Improper cup station alignment

•

Excessive sensitivity (the sensor is sensing the delivery door)

•

Cup station lens is not clean

As indicated in the Sanitation section, you should remove the cup station to clean it.  Pay particular 
attention to the dark colored infrared mug/cup sensor lens, which is part of the cup station.  If it is not 
thoroughly cleaned, the sensor will not work properly.

Cleaning the infrared mug/cup sensor unit itself is not usually necessary.  If it does require cleaning, 
just wipe it with a damp cloth.

1.

Remove the plastic cap in the rear of the sensing unit, exposing the potentiometer adjusting 
screw, as shown in figure B1.

2.

Turn the screw clockwise to increase sensitivity of cup detection, or counterclockwise to 
decrease sensitivity.
