Buckle Chute Proximity Sensor Error - Horizon Fitness PF-P3100 Manual

4 Mechanical Troubleshooting

4 - 5 Buckle Chute Proximity Sensor Error

- The proximity sensor inside the buckle chute detects
a sheet and counts the number of feeding. If there is
paper dust on the sensor detecting area, the
machine may not operate correctly.
- B22, 2nd buckle chute proximity sensor also decides
the operating timing of the feed clutch solenoid.
- B21/22 1st/2nd buckle chute proximity sensors are
positioned in front of the buckle chute stopper, and
slow down the feed speed right before the sheet hits
against the stopper to reduce shock and noise.
- Be sure to remove jammed sheets in the buckle
chute completely. Otherwise, it can cause the
machine malfunction.

Wiring and connection among B21 prox-
imity sensor 1, B22 proximity sensor 2 and
Pin 5, 6, 7, 8, 9, 10 of X20 buckle connec-
tor and Pin 5, 6, 7, 8, 9, 10 of CON4 on
QPM-243 are OK.
4.
When activating the B21 using a piece of
paper, LED L22 on QPM-243 lights.
Does the sensor detecting area get dirty?
Clean the sensor for the
first stopper from the top.

1.
If the sensor activates when there is no
paper dust around the sensor, check if the
detecting area of the sensor does not get
dirty with dust.
2.
Clean the detecting area using a cotton
swab, and check if the sensor activates
correctly.
3.
The sensor connector is connected cor-
rectly.
4.
The sensor bracket is not tilted.
