We recommend you check the bar code print quality with a bar
code verifier. If you do not have a bar code verifier or scanner,
check the bar code visually. A bar code that is in spec has
complete bars, clear spaces, and small alphanumeric characters
look complete. An in spec bar code may not look as good as one
that is too dark, but it has the highest scan rate.
V e r i f i e r
The verifier scans and checks the quality of bar codes as they are
printed. The optional verifier must be purchased separately. The
verifier scans parallel bar codes; it can not scan serial bar codes
or read the RFID data programmed into the label.
The verifier must be enabled and set up before you can scan
bar codes. For set up procedures, refer to your verifier's
Operating Instructions available on our Web site.
