Stop Button (4)
The EMERGENCY STOP button is shown in the
activated or in position on the PANEL TEST
screen. To test, turn the EMERGENCY STOP
button to the right. The button increases in
diameter confirming its deactivation. If you push
the button in, the EMERGENCY STOP button
switch decreases in diameter on the screen
confirming its operation. If you push in or pull out
the EMERGENCY STOP button on the main
control panel and the EMERGENCY STOP button
on the screen does not change in size, then the
EMERGENCY STOP button must be considered
faulty and should be inspected or replaced.

push the RESET button in. The button as seen on
the PANEL TEST screen decreases in diameter
confirming its activation. If you push in the green

Proximity Test
The next menu selection in the HARDWARE
TEST screen is PROX. TEST.
To access the PROX. TEST menu press the
PROX. TEST button on the HARDWARE TEST
menu screen.
The PROX. TEST screen provides a visual
indication of all the proximity switches used to
control the index and print heads. The indication is
used to confirm the operation of the particular
proximity switch.
Heads Front
Heads Rear
Across the top of the PROXIMITY TEST screen
are the Heads Front and Heads Rear indicators.
Push in the EMERGENCY STOP button.
The Heads Front and Heads Rear indicators
perform as follows. When a print carriage reaches
the front proximity switch, the indicator below the
print head will change to a red indicator. If the
indicator fails to change to a red indication, this
would indicate that the proximity switch should be
considered faulty and must be inspected and/or
replaced.
The same procedure is used to check the Heads
Rear indicators.
