Resetting your Scanner
If the scanner’s display locks up or stops operating properly, you might need
to reset the scanner. Caution: This procedure clears all the information you
have stored in the scanner. Before you reset the scanner, try turning it off and
on again to see if it begins working properly. Reset the scanner only when
you are sure it is not working properly.
