Troubleshooting (Advanced)
Barcode Reader (only for model with Barcode Reader)
Reading is not possible.
Fingerprint Reader (only for model with Fingerprint Reader)
The sensor does not enroll or authenti-
cate my fingerprint.
Confirm the reading angle.
Confirm that the barcode is readable (without damage, etc.).
Confirm the range for reading.
Be sure the reader is programmed to read the type of barcode you are reading.
The distance from the reader to the barcode is important. As a rule of thumb, a
farther distance should be used for a larger symbol to allow the raster pattern to
cover the symbol. In addition, a closer distance should be used for a thinner
symbol.
Return the Barcode reader to the default setting.
Slide your finger correctly. For further information about enrollment and authen-
tication, refer to "How to Use the Fingerprint Reader" (
