3.2 Troubleshooting 
Because of the printing method used by the US Mint, bills are not exactly identical. 
This will occasionally cause a bill to not be recognized on the rst run in an automatic 
detector. This may also occur if a bill is inserted with even a slight deviation from the 
required pathway. The Kolibri Bishop is an advanced machine and will never accept a 
counterfeit bill. If it recognizes a bill after the second or third attempt, you can be assured 
that the bill is genuine.
Several factors can cause the Kolibri Bishop to not recognize a genuine bill:
• Overly wrinkled, overly creased and overly worn bills
• A physical shock
• A sudden change in temperature or humidity
• Extended period of non-use.
If the Bishop consistently refuses to recognize genuine bills, turn the unit off, unplug it 
from the wall. Reinsert the plug and turn the machine on to perform a reset. 
What does this error mean?
