Laser scanner options:
"Double-scan checking": To minimize the possibility of misreads with very
poorly printed bar codes or when reading through windshields, you have the
option of forcing the WDP to keep reading until it gets two results that are exactly
the same. This "double scan checking" takes a little longer, but it will eliminate
misreads. To activate double scan checking:
Scan Start Setup
Scan Code 39
Scan E to enable double scan checking.
Scan End Setup
To disable double scan checking, scan F instead of E.
4-second beam: Another option with problem reading conditions is to increase
the length of the time the scanner attempts to read, from the default 2-second beam
to a 4-second beam. This would be very helpful using long range scanners which
needs additional aiming or scanning time. To select the 4-second beam:
Scan Start Setup
Scan 2 of 5
Scan F to select the 4-second beam
Scan End Setup
To return to the default 2-second beam, scan E instead of F.
Continuous Scanning Option for the CCD scanner: Sometimes it is desirable to
read sheets or lists of bar codes without having to activate the trigger before each
read. To activate the CCD continuous scanning:
Scan Start Setup
Scan Computer Interface
Scan B to select continuous scanning
Scan End Setup
To disable continuous scanning, repeat the above, substituting C for B.
To use continuous scanning with a laser scanner, scan D; however, you will have to
hold down the trigger while scanning. In either case, if you want to read the same
bar code twice in succession, you will need to release the trigger and pull it again.
Small quiet zones: Although we recommend quiet zones (white space on either
side of a bar code) of at least 0.25", this option lets the laser and CCD scanners
read bar codes with less than 0.2" quiet zones, the only drawback being an
extremely small increase in the possibility of substitution errors.
Scan Start Setup
Scan Computer Interface
Scan F to select small quiet zones
Scan End Setup
To return to normal quiet zones, repeat the above, substituting E for F.
