► Use Next or Previous to highlight Cycle Print Carriage.
► Select Run Diagnost.
► Ensure the print carriage moves smoothly over it’s full range of travel.
► Select Stop.
► Select Exit.
► Select Exit.
► Select Back.
10.5 CALIBRATIONS
10.5.1 Temperature/Humidity Sensor
The temperature/humidity sensor (located on I/O node board 3) is calibrated at manufacture and is
not adjustable.
NOTE
I/O node board 3 is located inside the print carriage extrusion and the temperature and humidity
are measured at this point. Due to heat sources, movement and air flow, it must be expected for
the temperature and humidity to vary throughout the machine.

The squeegee mechanism is driven backwards and forwards across the stencil by the print car-
riage. The squeegee printhead mechanism incorporates two stepper motors to drive the two
squeegees independently down onto the stencil when a print stroke is required. During the rear-
ward stroke, the front squeegee is in contact with the stencil performing a rear print stroke. During
the forward stroke, the rear squeegee is in contact with the stencil performing a forward print
stroke.
The pressure being applied during the print stroke is measured by a strain gauge bridge (located in
the spring beam assembly of the squeegee mechanism) and if necessary, a correction to the pres-
sure is made by the software.
