How to Calibrate Standard Bill Acceptors

SC Series Aceeptors

A properly calibrated note acceptor provides the best possible bill acceptance rate for your machine. Standard Change Makers designs their products with calibration procedures that you can perform at your location. With the 8051 upgrade, we've even made it automatic using the keyboard or data terminal.

Choose from the list of note acceptors below that matches your machine. The serial tag on the unit will help to identify the note acceptor if you are not sure which type you own.

The System 600-FST series note acceptor was introduced in 1998 to replace the System 500E acceptor. This bill acceptor used a more advanced CPU board and sensor technology, making it one of the best acceptors manufactured for the time. The acceptor end cap will have a red sticker that reads "System 600FST".

The System 600-EF series note acceptor was introduced in 2008 to replace the System 600-FST. This current bill acceptor used a faster CPU board, processor and sensor technology, and the EPROM software chip was replace with more current SD flash card technology. The System 600-EF wa sthe first SCM acceptor that could offer 4-way bill acceptance. The acceptor end cap will have a white sticker with a color U.S. flag (or flags of Canada and Mexico for those currencies) and reads "System 600EF".

The System 500 series note acceptor was sold in change machines from 1987 to 1994. This "end feed" bill acceptor was fully programmable, through a keyboard, to accept up to four different denominations of coins and bills. The power supply is a black 3x4x8 inch box, with an illuminated red switch. System 500 is printed on the black end cap of the acceptor.

The System 200 or System 200-A series acceptors were sold in model SC5 and SC5T change machines. This acceptor series has the stacker and an "end feed" type bill acceptor together as one unit. The System 200 has a flat, gray power cord with a red stripe on one side of the cord. The 200-A has a black power cord consisting of a group of colored wires banded together. Simple switch settings select the bills to be accepted.

Other Questions

If you have followed the instructions in calibrating your bill acceptor, and you have problems with bill acceptance or get errors when you return the machine to normal operation mode, you should contact the Standard Change-Makers Service Dept. by calling 1-800-968-6955 (or 317-899-6966).

Depending on usage, it is always a good idea to clean your bill acceptor with a clean damp cloth prior to calibrating it. A clean bill path will help with the calibration operation, as well as preventative maintenance will always help in better performance and reliability.
