Machined C Chase The machined C chase is the receptacle for the stencil during printing opera-
tions. The machined C chase accommodates the standard 29” by 29” stencil
size. The print stencil is clamped into place by the machined C chase during the
print cycle.
There are two methods used for achieving correct position of the stencil within
the chase assembly:
• Screen Depth Adjuster
• Screen Change Mechanism
There are two image scales on the screen depth adjuster:
• Centre Justified Image Scale
• Front Justified Image Scale
Screen Alignment
Module
The screen alignment module enables adjustment of the machined chase to
achieve optimum stencil to board alignment prior to the print stroke. Actuators
move the print stencil in the X, Y and theta planes to nullify the misalignment
error signal from the vision system.

Adjustable Screen
Mount (ASM)
The ASM is the receptacle for the stencil during printing operations. The ASM
is fully adjustable to accommodate the most popular of stencil sizes. The print
stencil is clamped into place by the ASM during the print cycle. The ASM is a
printer option replacing the C Chase.
There are two methods used for achieving correct position of the stencil within
the chase assembly:
• Screen Depth Adjuster
• Screen Change Mechanism
The screen depth adjuster is set (Distance to Image) by the operator prior to
loading the stencil. The stencil is loaded into the chase until it reaches the stop
at the end of the screen depth adjuster.
The screen change mechanism places the stencil in the correct position calcu-
lated by the software.
Screen Alignment
Module
The screen alignment module enables adjustment of the ASM to achieve
optimum stencil to board alignment prior to the print stroke. Actuators move the
print stencil in the X, Y and theta planes to nullify the misalignment error signal
from the vision system.

Adjustable Width
Screen Mount
(AWSM)
The AWSM is the receptacle for the stencil during printing operations. The
AWSM is fully adjustable to accommodate the most popular of stencil sizes.
The print stencil is clamped into place by the AWSM during the print cycle. The
AWSM is a printer option replacing the C Chase.
The screen change mechanism locates the stencil within the chase assembly.
Screen Alignment
Module
The screen alignment module enables adjustment of the AWSM to achieve
optimum stencil to board alignment prior to the print stroke. Actuators move the
print stencil in the X, Y and theta planes to nullify the misalignment error signal
from the vision system.
