STEP 4:
Final Photo Sensor
Adjustment
(continued)
If the photo sensor is to set too far from the
surface of the material, the read indicator on the
back of the photo sensor will simply turn On and
the feeder will start. This indicates the sensor is
out of range and therefore will be not “see” the
target.
NO TE
On the feeder, such objects as shafts, guides,
belts, and supports may cause false “reads” if
the photo sensor is not adjusted properly for the
material (or target). The resulting problem can be
intermittent or continuous feeding. See Section 5,
“Troubleshooting”, for a solution.

Black opaque objects may require a special photo
sensor. If the photo sensor fails to stop the feeder
when the material is within the target range, then
consult a qualified technician.

4. Simulate gripper jaw action by manually grasping the leading
edge of the bottom sheet and pulling completely away from
the gate assembly area. Once a piece is removed from the
gripper jaw, the sensor sends a signal to the feeder to “stage”
the next piece. The leading of the “staged” piece should be in-
line with the front hopper plate.
5. After running several sheets through, turn the feeder power
Off by pushing the circle ( O ) at the Power On/Off rocker
switch. Adjust the photo sensor as needed to achieve the cor -
rect stopping point. An optimum setting is to aim the barrel
slightly to the rear of the leading edge (Figure 27) . This com -
pensates for the slight over-travel of the motor after it turns
Off, thus allowing the leading edge to stop in-line with the
front hopper plate.
6. Retest the feeder as needed until optimum results are
achieved.
