Verifier Settings
This section gives a brief description of the verifier settings. 
Verification Type 
Select the verification type to check the barcode. 
• None - No barcode validation
• Read/No Read - Validate if barcode is readable
• ISO15415/15416 - Full ANSI grading of barcode
Passing Grade
Sets the minimum passing grade for barcode grading. Grade 0.0 (F) is the lowest 
grade. Grade 1.5 (C) is the default and recommended by ISO standard. Only 
applied when verification type is set to ISO15415/15416.
Aperture
Indicates the aperture size in mils (1000 mils = 25.4mm) used for verification. 
Aperture size will be chosen automatically based on ISO standard. Change only if 
required by an overriding application.
Maximum Consecutive Failures 
Sets maximum number of times printer encountered verification failure consecu-
tively before prompting for user action. This setting is only applicable when the 
Verification Failure Action is set to Void and Reprint.
Verification Failure Action
Indicates action to take when label fails verification.
• Void and Reprint (default) - Retract and void the failed label, then reprint the 
failed label. Stop reprint if the maximum consecutive failures have been 
reached.
• Ignore and Continue - No voiding when verification fails. Result is saved and 
next label is printed.
Note: Note: During multiple label printing, printer will void the failed label (plus all printed 
and yet to be verified labels) in order to keep the good labels in sequence.
Save Failed Label Images
When enabled, the printer saves all failed label images in non-volatile memory. 
Maximum 100 images can be saved (if memory available). At maximum capacity 
oldest image file will be replaced by newest.
