Primera Bravo II Calibration Instructions page 2

For any picking issues, first, try restoring factory defaults. This is done by clicking the
RESTORE FACTORY button. All values set by the testing technicians before the unit was
shipped will be restored. Test the Bravo at this point. 70% of picking issues are resolved after
restoring the factory defaults. If it doesn't resolve the problem continue with the following
instructions.
Now click on 'SET OFFSETS' button.
After changing any values you can click the Pick button to test the values without running a job.
C. Tricking the Lid Sensor
In order to make any changes to values, the Bravo's cover must be closed. Often it is difficult to
see inside the Bravo to make picking judgments with the cover closed. There is a way to open
the lid and watch the Bravo. You can simply block that optical sensor for the lid, which is found
roughly 3 centimeters to the right, and about 2 centimeters back of the power button on top
cover of the Bravo. You will see an opening, or 'notch' in the white casing of the Bravo. This
notch has the optical sensor inside it that detects when the lid is open. There is a corresponding
plastic tab located on the lid of the Bravo that fits down into that notch on top of the Bravo. The
plastic tab on the lid has the piece of reflective tape on it that blocks the optical sensor inside the
notch when the lid is closed. To block the sensor, you need to take a piece of cardboard, or
folded up paper, and wedge it down inside that notch, thus blocking the optical sensor, and
tricking the Bravo to think that the lid is closed.
D. Pick Depth Adjustments
If it appears the fingers are perfectly centered but just not going down far enough to pick the
disk, adjust with the following instructions:
Adjust the pick depth level by changing the values (with numbers in increments of 10) in the
'DISK SWITCH OFFSET' field. You should be at 50 or 60 right now. Try increasing the number
in increments of 10, then testing (See Section H) until you find the proper depth. Once you
change the value, Click Test to set it. Do not set this value over 80 under any circumstances. If
it is still not picking at 80, there are other problems with the unit that will need to be addressed.
