OVERVIEW

Auto Screen
Loader
The auto screen loader accurately positions the screen in the chase. The auto
screen loader is incorporated into the squeegee drip tray mechanism which is
secured beneath the print carriage, therefore the drive is provided by the print
carriage drive system.
Initially the screen is manually loaded and the front printhead cover/shutter is
closed. When Screen Change is selected on the MMI, the auto screen loader
is driven forward by the print carriage to locate the rear edge of the screen.
Once located, the auto screen loader is driven further forward allowing the auto
screen loader lever to clear the inner face of the rear frame of the screen. The
auto screen loader lever is driven down and the print carriage is reversed pulling
the screen to the rear of the chase. The auto screen loader lever is retracted
and the screen change mechanism is driven rearwards allowing the auto screen
loader lever to clear the rear face of the screen. The auto screen loader lever
is lowered and the print carriage is driven forwards, pushing the screen to the
correct position. Once the screen is registered in the correct position for
printing, the auto screen loader lever is retracted and the screen is secured in
position.

Screen Depth
Adjuster
The screen depth adjuster has two scales as follows:
The rear of stencil to front of image scale, marked on the top of the screen depth
adjuster, can be used for either centre justified or front justified stencils. The
scale has both imperial and metric units as follows:
• Metric - 150mm to 650mm
• Imperial - 6” to 26”
When using this scale the screen depth adjuster is set to the rear of stencil to
front of image value. The figure below shows this measurement for both centre
and front justified stencils
