“Return pin” denotes the twisted-pair return, to be
connected at signal ground level. For interface wiring be
sure to use a twisted-pair cable for each signal, and to
complete the connection on the return side. These cables
should be shielded and the ground connected to the
chassis of the host computer and the scanner.

The scanner has received incorrect commands from your
scanning software. When this error occurs, retry the scanning
operation. The scanner returns to normal operation when it
receives correct commands. Normally you do not need to
reset the scanner, which is done by turning the scanner off
and then on.

Fatal error
This error indicates one of the following problems:
The fluorescent lamp needs to be replaced.
Paper is jammed in the document feeder.
There is no document in the document feeder or the
document was not loaded correctly.
The software may not be set up properly.
Check to see if the fluorescent lamp is on. If not, the lamp
may need to be replaced. Contact your dealer or a.qualified
service person for assistance.
Turn off the scanner and remove any paper that may be
jammed in the document feeder. If the scanner still does not
operate properly, or if this error occurs repeatedly, consult
your dealer.
Make sure the document is loaded correctly in the document
feeder, and then resume scanning.
Check to see that your software is installed correctly. Also
make sure you have selected the correct device driver for the
scanner. See your software manual for details.
