Problem
Possible solution…
Scanner Faults are generated
when scanning.
Note:
•
Faults are normal when
a bar code has defects,
including
insufficient
quiet zones that can
make it unreadable.
•
Adjust the HEAT and/or
PRINT SPEED settings
to achieve print quality.
Consult your software
application (or make
changes via the User
Interface; see the
Operator’s Manual for
details).
Try the following –
Examine the print quality of the failed label: If the bar code(s) appear(s) to be
free of voids with sufficient quiet zone space, ensure that the scanner is down,
centered over the labels, and secured with the Thumbscrew.
Dirt or debris could be covering the scanner window: Turn OFF the printer.
Examine the window for obstructions and clean if necessary; see
Maintenance.
The bar codes may be too close together: For multiple-up identical bar codes,
ensure sufficient white space between rows; see Operation.
Ambient lighting could adversely be affecting readability: Reduce / redirect
bright light sources, or increase light in dim areas.
Reflected light off the media may be blinding the optics: Ensure that the label
stock has a matte finish, and not a reflective or glossy surface; see Operation.
The label exit angle may have changed: Ensure that the Tear Bar, Peel
Mechanism, or Rewind Plate has been mounted to the printer and that the
label pathway is unobstructed; see the Operator’s Manual for details.
Current scanner settings may be too restrictive: Try decreasing the MIN
READABLE HEIGHT or REDUNDANCY LEVEL setting, lowering the print
speed, or increasing the height of the bar code; see Operation.
The bar code may not be recognized: Ensure that the symbology is
supported; see Specifications.
The symbology may not be generated by as a font: Bitmapped bar codes or
those containing certain addendums must be specified by number (BAR
CODE COUNT in the menu); see Operation.
The focal length may be incorrect for the bar code resolution: Consult your
software application for the bar code X dimension, and then ensure the scan
position matches and if not change it; see Maintenance.
If problems persist, yet the bar codes are readable on other devices, scanner
misalignment is possible; see Alignment. If you have questions, please contact
Datamax-O’Neil Technical Support.
