A Working Guide to Troubleshooting the CT550
The CT550 is a simple product which does not have much that can go wrong with it. If you are
experiencing issues with your machine, below are several items you can first troubleshoot for yourself in
an effort to find out what the problem may be.
1. Bill Feeding
Perhaps the most important single factor in understanding how to use the CT550 is to be aware that
the CT550 is uni-directional. This means that the
CT550 will only recognize the bills if they are fed in
the proper direction, with the proper alignment.
INCORRECT FEEDING OF BILLS IS THE NUMBER
ONE CAUSE OF BANKNOTES BEING REJECTED IN
ERROR.
Bills should be fed “face-up”, with the top of the
head of the historical figure facing the right. The bill should be fed so that the right edge of the bill is
touching the right side of the bill feeding tray. In this way, the bill will be properly aligned with the
many different sensors inside the CT550 and the security features of the banknote may be properly
read and decoded.
It is also important to note that no two US dollar bills are the same. Variations in size, age, degree of
dirt or other soiling of the bill, and potential exposure to chemicals (such as laundry detergent) may
cause a bill to be difficult to decode. For this reason, we highly recommend that any bill be tested at
least three times before being suspected.
2. Power Cable Damage
Sometimes, the thin cable that extends from the adaptor to the back of the CT550 unit can get
damaged –especially if it has been installed in a manner that allows the cable to have pressure
applied to it. Often, the tangle of cables behind a workstation can
cause this to happen.
To confirm the adaptor is not damaged, plug the adaptor into the
wall and into your CT550. Then, look to see if the green LED light
is lit. If the green LED does not light up, it may be necessary to
replace it.
If you have another CT550 unit in your location, it is a good idea to test the functioning of the CT550
with the other unit’s cable prior to contacting FraudFighter to try to replace your machine.
