Two Button
Control Switches
Located on the upper side panels, either side of the printhead cover, are the two
button control switches or jog switches. These buttons are positioned such as
to maintain maximum safety for the operator whilst solvent priming or paper
feeding with the printhead cover open. This requires both buttons to be
depressed simultaneously for the function to become active. The use of these
buttons is dependent on the function selected on the machine monitor. During
normal operation these buttons control paper feed and solvent prime opera-
tions. When in maintenance mode the two buttons also control the following
diagnostics:
• Print Carriage
• Squeegee Assembly
• Camera Axes
• Rail System
• Screen Align
• Rising Table
•ProFlow
Only one button is required to drive the selected mechanism, the two buttons
are used to drive the mechanism in opposite directions, ie jog forward or jog
back.

EMERGENCY SHUTDOWN
The machine is fitted with an emergency stop push button control switch (E
Stop). The E Stop switch, once pressed, is a latching switch and requires
resetting. To reset the E Stop, turn the button clockwise until it unlatches.
Pressing the E Stop or raising the printhead cover cuts the servo axes power
supply. A warning of this condition is reported on the machine monitor.
