WARNING
BOARD CLAMPS. EXTREME CARE MUST BE EXERCISED WHEN
WORKING IN THE TOOLING AREA OF THE MACHINE TO AVOID
INJURY. THE FOILS ON THE FRONT AND REAR BOARD CLAMPS
ARE VERY SHARP.
The sensitivity should be adjusted to see a board on the rails at transport height.
The distance between the top of the board and the top of the tooling can change,
due to different board thicknesses, even if the same underside clearance param-
eter is used. The optimum adjustment is achieved using the thinnest board, down
to a minimum of 0.4 mm thick. If the sensor is adjusted and later a thinner board
is used in the machine, it is possible that the decreased distance between the
sensor and the tooling may cause the sensor to be activated while no board is
present, due to tooling be positioned directly below the sensor. If a 0.6 mm board
is not available, extra care should be taken to ensure that the sensor is detecting
only the top of the board used.
1. In Diagnostics select Camera Axes module.
2. Select Home Camera X Axis. Select Home Camera Y Axis.
3. Select Exit. Select Rail System diagnostics.
4. Ensure the rail width is set to the width of the board using Drive Rail to
Board Width (if the board being used for the adjustment is not in the current
product file, adjust the rail width using Drive Rail Width Using Two Button
Control).
5. Select Exit. Select Camera Axes diagnostics.
6. Select Drive to Board Stop Position. Select Exit.
7. Select Print Head diagnostics. Select Raise Head Under 2 Button Control
and fit the head prop.
8. Position the test board (a 0.6 mm board if available) on the rails below the
sensor.

9. If the red LED on the sensor is illuminated, turn the sensitivity/focal length
adjustment anti-clockwise using a plastic trimmer tool until the LED extin-
guishes (or the LED is flickering).
10.Turn the sensitivity/focal length adjustment very slowly in a clockwise
direction until the instant the LED is fully illuminated (the LED may flicker
before fully illuminating).
11.Turn the control in a clockwise direction approximately 10 to 20 degrees
beyond the point at which the LED illuminated.
NOTE
Turning the control more than 10 to 20 degrees beyond the point at which
the LED first illuminated may cause the sensor to detect the tooling whilst
printing using thin boards.
12.Remove the test board from the machine. Remove the head prop and lower
the printhead.
13.Select the System button. Exit from diagnostics, the machine initializes.

Board Stop In
Sensor
The Board Stop In Sensor is mounted on the camera carriage and has an LED
mounted in its body which illuminates when the beam is broken.
When the board stop is home (raised) the LED is on as the beam is broken by
the vane. The only adjustment is on the opto pillars which must be set to enable
the beam of the opto to look through the slot of the vane giving definite up/down
detection.
