Overview
The online data validator (validator) is an external bar code
scanning device attached above the paper exit of the printer. When
activated, it scans the printed output looking for bar codes. When it
finds a bar code, it determines what type of bar code it is and
monitors the bar code quality as it passes through the scan area.
After the entire bar code has passed under the scanning beam, the
validator grades the bar code and sends a report to the printer. How
the printer responds is determined by the validator settings,
Operational Parameters
The design parameters of the validator are as follows:
•
The validator can track the performance of up to four horizontal
bar codes at one time.
•
The validator requires a minimum distance of 1/2 inch or 20
times the minimum element width (x-dimension), whichever is
greater, between bar codes.
•
The validator recognizes the following linear, picket fence bar
codes: Codabar, Code 39, Code 93, Code 128, Interleaved 2 of
5, and UPC/EAN + add-ons.
11

Chapter 1 Overview
•
The validator can also evaluate PDF 417 bar codes. For PDF
417 Limited, the validator works best with security level 5 or
higher, using the current default printer settings for Defects
Percentage, Percent Decode, and Decodeability. For lower
security levels, lower the Defects Percentage to 5% to enable
checking for bar code damage.
•
•
Stacked, 2D, and vertical (ladder) bar codes are not supported.
Bar codes must have a minimum x-dimension of 10 mil
(0.010 inch) to be recognized by the full width of the scanning
beam. The validator can recognize bar x-dimension as narrow
as 6.6 mil (0.0066 inch) for 300 dpi printers, and 10 mil
(0.010 inch) for 203 dpi printers. The validator cannot
recognize x-dimensions smaller than 6.6 mil (0.0066 inch) or
larger than 40 mil (0.040 inch).

Basic Validator Setup
Unit Positioning
The validator must be positioned so that the scanning beam covers
the entire area containing the bar codes, including the area
required for quiet zones. The validator can be moved along the
lower bracket and aligned with any of the inscribed hash marks,
depending on the size of the labels printed and the positioning of
the bar codes on those labels. In addition, the beam width can be
If a bar code is completely outside of the scanning area, straddles
an edge, or does not pass completely under the scanning beam,
the validator interprets it as a missing bar code and generates error
conditions.

The front panel of the validator has the following controls and
indicators:
•
•
POWER: Indicates the validator is at full power.
CALIBRATION: Flashes when the validator is in calibration
•
•

Defining Validator Options
A number of validator options which define specific parameters for
certain print jobs can be set from the printer configuration menu.
Setting Number Of Bar Codes On A Form
You can define how many bar codes the validator should expect on
a form. This setting is required when bar codes are produced as a
part of a larger bitmapped image. When set to a specific number,
the printer checks after a form has printed and passed the validator
and determines if it has received an analysis report for each bar
code. If the printer does not have as many reports as it expects, it
can assume a gross bar code failure.
When Auto is selected, the printer only expects as many bar code
analyses as bar codes printed using printer bar code commands
defined by the host software.

Decodeability
You can determine how strict the validator grades the wide/narrow
bars and spaces which compose the bar code by setting the
Decodeability parameter to a percentage value from 30% to 90%.
The higher the percentage value chosen, the stricter the validator
grades.
For example, if the Decodeability value is set to 37%, the validator
gives the bar code a failing grade if the decodeability of the bar
code is at or below 37%.

Percent Decode
You can set how strict the validator grades each bar code. For
example, the Percent Decode default value is 60%. This means
that 60% of the scanned bar code must be readable for the
validator to give the bar code a passing grade. You can set the

Print Speed Limits
Operation
There are a number of factors which contribute to successful bar
code validation, including printer speed, demand print settings,
calibration, and ambient light. The following sections describe how
to ensure your bar code validator is scanning and reporting
properly.
Print Speed Limits
Two factors in the validation process affect the printer’s speed limit:
bar code height and the validation report type selected.
Bar Code Height (Min. Code Height)
The validator cannot function at the highest speed possible by the
printer. It requires a minimum number of scans per bar code to
make a reliable assessment, so the speed of the printer is limited
by the height of the bar code. If the bar code is very short, printing
needs to be slowed down to allow sufficient scans to occur. If the
print speed exceeds this limit, the message, “Speed Exceeds
Validator Limit” will display. Print speed will be lowered
automatically if required, but will not automatically reset to a higher
speed.
The printer cannot predict how high all the bar codes in a given job
will be, so it cannot automatically limit or adjust the print speed to
insure the code height/speed requirement is being met. When the
bar code is too short for the selected speed, the printer produces a
missing bar code error condition. Therefore, printer speed must be
set manually to compensate for bar code height.
Use this formula to determine printer speed in relation to bar code
height:
Bar Code Height In Inches
Maximum Printer Speed In
=
Inches Per Second
0.04

Chapter 2 Operation
For example, a bar code 1 inch in height can scan successfully at a
printer speed of 25 inches per second; a bar code 1/8 inch in height
can scan successfully at no more than 3 inches per second.
By changing the Min. Code Height, the printer and slew speeds will
be changed automatically.
To change the Min. Code Height:

Print Speed Limits
Validation Report Type
Another factor that limits print speed is the type of validation report
selected. The printer automatically examines the selected report
type and sets the defined maximum slew (vertical paper
movement) and print speeds to insure proper operation. If the
current speed selected in the menus is higher than the maximum,
the value is changed to equal the maximum. If the current menu
setting is lower than the newly set maximum, no change in speed
occurs.
Min. Code Gap
Bar code
Min. Code Gap
Distance from the
bottom of a bar code to the
top of the next bar code
Next bar code
Minimum Code Gap represents the distance between the closest
bar codes within a print job. The distance is measured from the
bottom of one bar code to the top of the next bar code. The closest
bar codes can be located on two separate labels or on the same
label.
This distance is important because it affects how fast the Print
Speed can be set. If the bottom-most bar code on one label is very
close to the top-most bar code on the next label, the printer could
have trouble distinguishing which bar code correlates with which
label. To avoid the risk of miscorrelation, the printer automatically
set its Print Speed.

8. Press PAUSE again to put the printer online.
NOTE: To avoid the risk of miscorrelation, the printer automatically
sets its Print Speed based on the information that has been
selected to ensure validation results are accurate.
Demand Printing Modes
In order for each bar code to be successfully validated, the entire
bar code must pass completely under the scanning beam, even
when the printer is set up for demand printing mode. In cases
where the bar code is close to the bottom of a label and the printer
is in a demand print mode, the printer automatically pushes the
label past the scanning beam. Once the bar code is validated, the
printer retracts the label back to be cut or torn off.
Because the printer has to push out and then retract labels in
demand modes, the extra movements slow the printing process.
You can avoid this by adjusting the form so that the bar code
appears early enough on the form so that it will pass completely
under the scanning beam during normal printing. This may involve
rotating the form or moving the bar code to a different position on
the form.

Bad Bar Code Error Detection
Bar Code Failures
The validator tells the printer to announce a fault condition in two
situations:
•
•
if the validator detects a bad bar code
if the validator detects no bar code where it expects to find one.
How the printer reacts to these faults is determined by the printer’s
configuration settings, as described below.
Bad Bar Code Error Detection
The validator examines every bar code that passes under the
scanning beam and sends an analysis report to the printer. If a bar
code is reported to have failed to meet any of the acceptance
criteria, an error condition is reported. How the printer then reacts is
Missing Bar Code Error Detection
A bar code may print so poorly that the validator cannot detect it,
and the printer does not receive an analysis report for the code. To
catch this problem, the printer tracks the position of the last label
printed and knows when it should have completely passed the
scanning beam. It can then compare the number of bar code
analysis reports it expected to the number it received. If the printer
does not receive enough bar code reports, it enters an error
The number of bar codes expected is determined one of two ways:
•
If “Auto” is selected for the “Number of Codes” parameter, and
you are using LinePrinter Plus®, IGP®/PGL®, IGP Code V™, or
IPDS™ graphics software, the printer compares the number of
bar code commands it receives from the software to the
number of analysis reports it receives from the validator.

Stop
If the system detects a bar code failure, the print job stops, the
printer status indicator lamp flashes, the alarm sounds, and the
appropriate error message displays.

Error Action
The printer remains in a fault condition until you press the PAUSE
key. This clears the error message and takes the printer offline.
You must correct any condition that may have caused the fault.
When ready, the printer can be put back online and it will resume
printing where it left off.
Overstrike
Use Overstrike mode when you want bad labels to be marked, but
not reprinted (i.e., when using pre-numbered labels).
If the system detects a bar code failure, the print job stops, the
printer status indicator lamp flashes, the alarm sounds, and the
appropriate error message displays.
Without pausing, the printer then automatically reverses to the top
of the form containing the failing bar code. It then prints an
obliterating pattern over the form and any other forms partially
printed prior to the physical stop. By default, the obliterating pattern
is a grid of fine lines which clearly marks the label as bad but allows
you to read what was originally printed.
In the VALIDATOR menu, the Overstrike Style options are: Grid,
Grey, Checkerboard, or Error Type Msg.
NOTE: To see the error message printed on the bad label as the
Overstrike Style, select the Error Type Msg option.
After the overstrike printing, the printer clears the error message
and stops the alarm, then resumes normal printing at the point the
job was stopped. The overprinted labels are lost and a separate
print command is required to resend them from the host, if needed.
Retry Form
This mode is similar to the Overstrike mode, however, instead of
resuming printing where the printer had left off, the printer will
attempt to reprint the bad form.
NOTE: The number of times the printer will attempt to reprint the
bad form is determined by the Num Retry setting. See

Chapter 2 Bar Code Failures
The printer will stop, indicate an error, and overstrike as described
above. Then it will skip a number of blank labels, depending on the
It will then slew to the next top of a blank form and reprint the entire
form that contained the bad bar code and any other forms that were
perhaps interrupted by the error.
NOTE: Because of physical differences between the location of the
print head and the scanning beam, it is likely that a second
form will be started before the first form has finished being
assessed. Therefore, the reprint operation will need to
reprint more than just the form with the error.
If the printer has to reprint the same form five times in a row, the
print job stops completely and behaves the same as in Stop mode.
Error Messages
The validator can detect a number of errors. When one of these
errors occurs, the validator alerts the printer to perform the currently
