Before the shutters are opened, if you get a signal level greater than 200 millivolts, it
usually means that there is noise on the scanner inputs, which most times is caused by
an electrical problem with the scanner. If you cannot isolate and fix the cause of this
problem, call STC for help.

Before the shutters are closed, if you don't get a calibrated temperature in the range of
178°F to 182°F, it means that the scanner wasn't calibrated. If cleaning the optics
doesn't solve your problem, replace the scanner cover-and-module assembly. If this
doesn't solve your problem, call STC for help in fixing the problem.
