BC-3500 Bill and Coin Changer
Coin or Bill Return Button
When the COIN or BILL RETURN button (see Figure 1-6) is depressed, a switch closes and sends a signal to the
CCC. The coin lockout coil in the coin acceptor is released and the transport motor rotates in the reverse direction.
If the bill reject button is pressed (ON) for more than 10 seconds, the transport will turn OFF automatically to prevent
excess wear and overheating and the message “CK BILL RETRN SW” will be displayed and the switch will be ignored
until the FUNCTION button is pressed.

Hoppers
The bill changer contains three coin hoppers (see Figure 1-7) which mount on the front surface of the dispenser
assembly and pivot forward from the bottom for loading, unloading, and removal (see Table 1-2 for required
hopper types and capacities).
The hopper transports coins to the detectors and coin chutes by means of a chain conveyor, which is driven from
below by a sprocket. The chain follows a serpentine path, so that excess coins fall back into the hopper ensuring
only one coin per pin enters the coin counting area.
The chain picks up coins from the bottom of the hopper and carries them up to the top, where they fall through the
upper chain guide ring and interrupt a light beam to a photodetector, which is mounted on the dispenser. The required
number of coins for a desired change combination are counted in this manner as the coins then fall through a closed
chute to the escrow bucket.
An agitator, which is mounted on the drive shaft of each hopper, agitates the coin load to minimize coin jams in the
hopper and ensure efficient coin pick up.
To reduce jams and minimize the need for cleaning, the hoppers in the BC-3500 also have Teflon-coated coin tracks.
