ADA CONTROL BOARD INFORMATION AND SERVICE
The ADA feature is located in the front of the drip tray and controlled through a USB connector from the ADA board
to the computer. The ADA feature is a capacitance touch control board activated by an object changing the capaci-
tance field and sending a signal to the computer.
ADA Control Board Diagnostics
Before replacing the drip tray or the ADA board it is possible to determine if the board is faulty by plugging the USB
output into a computer. The control board acts like a mouse and will move a cursor on a screen. If the cursor moves
appropriately, the board is not the problem.

below.

pulling/removing the 4 panel clips (save the panel
