Lid Bolt A pneumatically operated lid bolt is fitted to prevent the printhead cover from
being raised during the print cycle.
The lid bolt is withdrawn and the printhead cover may be raised:
• When Open Cover is requested by software
• When pause or stop is selected during a print cycle
• When the EMO is pressed
Safety Devices The safety features designed into this machine are for the protection of all
operator and maintenance personnel. ASM strongly recommend safety
devices are never overridden.
Two Button
Control Switches
The two button control switches or jog switches 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 button control switches control the
following diagnostics:
• Print Carriage
• Squeegee Assembly
• Camera Axes
• Rail System

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
If an emergency stop is initiated via an EMO, all power and pneumatics to the
paired machines are removed. Electrical power remains to the M39 EMO
enclosure via the mains isolator but is removed from there to the M37 power
supply unit. Switching mains isolator to OFF removes electrical power from the
M39 EMO enclosure. Pneumatic supply is also closed off and any pressurised
air remaining within the machine’s system is vented via the pneumatic dump
valve.
