Photosensor Test
This test will determine if the photosensor is functioning correctly for the application.
1. Place the product in front of the photosensor as in normal operation.
2. The LED on the rear of the photosensor should illuminate.
3. If it does not, press and hold the white "teach" button on the rear of the photosensor for
approximately 1-2 seconds. The rear LED will change state and stay on after it has
been "taught".
4. Remove the product from the front of the photosensor.
5. The LED on the rear of the photosensor should extinguish.
6. If it does not, make sure that there are no objects in the path of the photosensor. If nec-
essary, remove the photosensor from the bracket and hold into open air.
7. Re-teach photosensor as necessary.
NOTE:
The test object should be a sample of the actual product.
NOTE:
If the LED on the photosensor fails to illuminate when an object is placed in front of
(but not touching) it, then it indicates that the photosensor is disconnected, or the power
supply or photosensor have failed.
Print Head Ink Pressure Test
This test will determine if the print head pressure is correct.
1. Connect the ink pressure gauge (5700-743) to the ink out port on the rear of the print
head.
2. While printing (not purging), check the pressure; refer to the print head pressure chart
for the optimum pressure for your print head. The ink pressure gauge must be level
with the print head. Note that pressure can vary by as much as 0.75 PSIG while print-
ing.
3. Pressure should be such that the nominal print head pressure is centered within the
deflection of the gauge
If pressure is not correct, see
Setting Ink Pressure
in
Section 4, Installation
.
Ink Regulator Input Pressure Test
This test will determine if the regulator input pressure is within operational range.
1. Connect ink pressure gauge to end of ink line where effluent line is normally attached.
2. Check that pressure does not fall below 10 PSIG at any time.
NOTE:
The lowest pressure should be just prior to when the pump turns on.
