6. Troubleshooting
Both the computer and the scanner can produce fatal errors and warnings. All messages are
numbered. Messages with message numbers < 1000 come directly from the scanner
controller and are potentially serious. Message numbers >= 1000 are generated by program
mar345 and may be a consequence of a controller error or some other kind of malfunctioning
or warning.
If you don’t know how to fix a scanner problem, contact marresearch. We will usually
ask you right away to send us the mar.spy file and the mar.log file where the error
occured (see chapter 2.3) since they contain almost all information we need.
The following error messages >= 1000 are produced by program mar345:
_______________________________________________________________________
No.
