Instructions
Overview
The online data validator (ODV) 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,
explained in “Configuring The Validator” on page 50.
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.
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).
Refer to Table 1 for the minimum x-dimension requirements for
each printer size of a 300 dpi printer.

Scanning Beam
Notch in Tear Bar
Figure 18. Scanning Beam Location
Peel-Off Media Handling Mode
If your printer is configured for Peel-Off Media Handling mode (use
of optional internal rewinder), you may need to align the beam
further behind the notches (0.14 to 0.20 inches [3.56 mm to
5.07 mm] from the front edge of the tear bar) so that the peeled
label remains on the tear bar and the trailing edge of the last bar
code can still pass completely under the scanning beam. See
Figure 19.
Aligning the scanning beam to any position other than the notches
on the tear bar should only be done if the last printed bar code
image does not clear the beam when the label is at the peel-off
position after printing. In addition, the distance the beam moves
back from the tear bar edge must correspond to a distance from the
leading edge of the label that does not have bar code printing. For
example, aligning the beam 0.16 inches from the front edge of the
tear bar requires that 0.16 inches of the leading edge of the label
must not have bar code images.

Operation
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 beam width can be moved
horizontally to the left or right (see “Shifting The Scanning Beam”
on page 39).
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.
Validator Front Panel
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
mode. See page 40 for calibration instructions.
•
READ: Flashes when the validator is reading a bar code.
•
1 and 2: Used for maintenance purposes only.
•
RESET: This button has three functions, depending on how
long you hold the button down. See Table 3 on page 46.

Chapter 2 Configuring The Validator
Configuring The Validator
Setting validator options is done through the printer configuration
menu. The validator comes equipped with a default setting for each
configuration option, and it works without having to change any of
these options. However, in some cases it is necessary to adjust
these options, which are described below.
NOTE: If you make any changes to the default configuration menu
items, you will be prompted to save the configuration.
See “Auto Save Configuration” in the User’s Manual.
Enabling And Disabling The Validator
Software can automatically detect an installed validator when the
printer is powered up. If the printer is powered up with Power-Up
Config. set to Factory, the VALIDATOR menu will be available and
Validator Funct. is set to Enable in the QUICK SETUP and
VALIDATOR menus.
If Power-Up Config. is not set to Factory, the VALIDATOR menu
will be available, but Validator Funct. is set to Disable. Enable
Validator Funct. by completing the following steps. (This is a onetime setting once you save the configuration.)

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
assumes a gross bar code failure.
When Auto (the default) 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.

The following items are considered advanced items and are only
visible if Admin User is set to Enable (in the PRINTER CONTROL
menu). Refer to the configuration section of your User’s Manual for
more information.
Decodeability
NOTE: This parameter factors into the Overall Grade (page 63).
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. The default is 37%.
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
NOTE: This parameter factors into the Overall Grade (page 63).
You can set how strict the validator grades each bar code. For
example, setting Percent Decode to 60% 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 Percent Decode parameter
to a percentage value from 0% to 99%. The higher the percentage
value chosen, the stricter the validator grades.

8. Press PAUSE again to put the printer online.
Defects
NOTE: This parameter factors into the Overall Grade (page 63).
You can set how strict the validator grades the irregularities such as
voids and spots found within elements and quiet zones for each bar
code. For example, the Defects default is 21%. This means that if
the bar code and quiet zone defects exceed 21%, the validator
gives the bar code a failing grade. You can set the Defects
parameter to a percentage value from 0% to 100%. The lower the
percentage value chosen, the stricter the validator grades.

Overall Grade
This menu item sets the value used by the validator for pass/fail
threshold during the analysis of bar codes. Instead of a letter grade,
numbers are used to allow for more resolution. The numbers can
be translated to letter grades according to the 4.0 grade table
below.
Table 4. Grading Scale for Overall Grade
Letter Grade
Grade Numerical Range
A
3.5 to 4.0
B
2.5 to 3.4
C
1.5 to 2.4
D
0.5 to 1.4
F
0.0 to 0.4
Any bar code with a grade below this threshold value will cause the
printer to display the Overall Grade Fail error message (see “Error
Messages” on page 92) and take the appropriate error action.
Higher values create a stricter pass criterion.
The Overall Grade is determined by taking the lowest grade
obtained for any of these bar code quality parameters:
Decodeability, Percent Decode, Defects, Modulation, EC Min,
Rmin, and Symbol Contrast.
You can set the Overall Grade parameter to a value from 0.0 to 4.0.
The default is 0.0.

Chapter 2 Configuring The Validator
Overall Grade Calculations
The validator follows the specified algorithm defined in the ANSI
X3.182 specification for determining the Overall Grade based on an
average. Although it is not defined, the validator truncates the result
of all analysis parameters averages for a slightly stricter grading.
A side effect of the ANSI specified algorithm is that the Overall
Grade may be lower than any of the averaged analysis parameters.
This occurs because the Overall Grade is based on the lowest
grade on any scan converted to a single digit grade (A to F, 4 to 0)
which is then averaged. This usually occurs when a single analysis
parameter has a value just above or just below the Overall Grade.
Example
The Decodeability value of 51 displays as B, but the Overall Grade
displays as C.
The bar code was scanned five times: three scans had values of
0.49 (grade C) and two scans had values of 0.54 (grade B).
The Decodeability grading calculation is:
(3 x 0.49) + (2 x 0.54) = 2.55
2.55 ÷ 5 = 0.51 (grade B)
The Overall Grade calculation is:
(3 x 2.0) + (2 x 3.0) = 12
12 ÷ 5 = 2.4 (grade C)
Also, with certain combinations of multiple analysis parameters and
possibly the truncation used on the analysis parameter’s average,
the Overall Grade may be higher than an individual analysis
parameter grade.
Example
The Decodeability value of 48 displays as C, but the Overall Grade
displays as B.
The bar code was scanned five times: four scans had values of
0.51 (grade B) and one scan had a value of 0.40 (grade C).
The Decodeability grading calculation is:
(4 x 0.51) + (1 x 0.40) = 2.44
2.44 ÷ 5 = .49 (grade C)
The Overall Grade calculation is:
(4 x 3.0) + (1 x 2.0) = 14
14 ÷ 5 = 2.8 (grade B)

Advanced Validator Options
Modulation
NOTE: This parameter factors into the Overall Grade (page 63).
Modulation measures how well the scan laser sees the wide
elements (bars or spaces) relative to the narrow elements. In
general, scanning lasers see bars better than spaces and wide
elements better than the narrow elements. This menu item sets the
value used by the validator for pass/fail threshold during the
analysis of bar codes. Higher values create a stricter criterion for
passing.
You can set the Modulation parameter to a percentage value from
0% to 100%. The default is 0%.
1. Press ... to take the printer offline and place the printer in
Menu mode.
2. If necessary, press ↓ and ↵ at the same time to unlock the

7. Press ↓ and ↵ at the same time to lock the ↵ key, then press
PAUSE to take the printer offline.
8. Press PAUSE again to put the printer online.
EC Min
NOTE: This parameter factors into the Overall Grade (page 63).
The higher the value, the stricter the criterion for passing.
This menu item sets the minimum edge contrast, which is the worst
edge transition (bar to space or space to bar) used by the validator
for pass/fail threshold during the analysis of bar codes. Bar codes
with an edge contrast below this threshold will fail.
You can set the EC Min parameter to a percentage value from 0%
to 100%. The default is 0%.
1. Press ... to take the printer offline and place the printer in
Menu mode.

8. Press PAUSE again to put the printer online.
Rmin
NOTE: This parameter factors into the Overall Grade (page 63).
This menu item sets the minimum reflectance value used by the
validator for pass/fail threshold used during the analysis of bar
codes. A bar code will fail if all the bar reflectance values are above
the percentage of space reflectance set by this threshold. For
example, an Rmin setting of 50% requires that at least one bar
reflectance value fall under the mid point of the reflectance value
read for the highest space reflectance.
You can set the Rmin parameter to a percentage value from 0% to
100%. The default is 100%.

Symbol Contrast
NOTE: This parameter factors into the Overall Grade (page 63).
The higher the value, the stricter the criterion for passing.
Symbol Contrast represents the contrast between the bars and
spaces in the bar code used by the validator for pass/fail threshold
used during the analysis of bar codes. The bar code must have a
certain level of contrast to be recognized by the validator. Bar
codes with a symbol contrast below the threshold will fail.
You can set the Symbol Contrast parameter to a percentage value
from 0% to 100%. The default is 0%.
NOTE: To disable this parameter, set Symbol Contrast to 0%.

8. Press PAUSE again to put the printer online.
Gain
This menu item sets the scanner gain setting (when a non zero
value is set). This allows you to adjust the amplitude (height) of the
space/bar transitions as seen on a Scan Profile to optimize the
validator hardware for applications where standard settings make
the bar codes unreadable. The range is from 0 to 255.
NOTE: If you want the validator to automatically adjust its Gain
setting during a validator calibration, set Gain = 0 and
Offset = 0. Gain and Offset are automatically adjusted
during calibration only if both Gain = 0 and Offset = 0.
67
Chapter 2 Configuring The Validator
Offset
This menu item sets the scanner offset setting (when a non zero
value is set). This allows you to adjust the vertical position of the
Scan Profile to guarantee that the validator hardware is reading the
bar codes within the optimal range. You can adjust this to place the
bar code profile in the center of the profile scale above 10% and
below 90%. The range is from 0 to 255.
NOTE: If you want the validator to automatically adjust its Offset
setting during a validator calibration, set Offset = 0 and
Gain = 0. Offset and Gain are automatically adjusted during
calibration only if both Offset = 0 and Gain = 0.
SN Threshold
This menu item sets the SN (signal to noise) threshold used by the
validator to discriminate between high peak noise and actual bar
code transitions. Any reflectance transitions that are below the
threshold are ignored and considered noise.
You can set the SN Threshold to a value from 5 to 199.
The default is 70.

Min. Read Scans
This menu item sets the minimum number of scans per bar code
that must be read. If less than the minimum number is read, then
the “Unscannable / xx Missing Codes” error message is generated.
To ensure that the validator accurately validates the bar codes, set
the Min. Read Scans value to 75% of the number of scans possible
per bar code (rounded down).
Use this formula to determine the number of scans possible per bar
code in relation to print speed and bar code height:
100 x Bar Code Height In Inches
Print Speed (Inches Per Second)
=
Number of Scans Possible
(rounded down)
Set Min. Read Scans to 75% of the Number of Scans Possible
value.
IMPORTANT
If you have more than one bar code on the form, use the
shortest bar code for the calculation.
Example
For a 0.5 inch tall bar code printing at 4 inches per second:
100 x 0.5
4
=
12 Number of Scans Possible
(rounded down)
Set Min. Read Scans to 75% of 12, which is 9.

Chapter 2 Configuring The Validator
Scan Report
IMPORTANT
To print a Scan Report, Telemetry Data must be set to
Full Report.
This executable menu item prints a diagnostic printout of bar code
analysis parameters calculated by the validator. It allows you to
determine which parameter may be the cause of bar code
verification failures. The report printed is based on the last Full
Report received from the validator. This allows you to send a bar
code print job to the printer, have the bar code scanned by the
validator, and view a report of the parameters as seen by the
validator.
For forms with multiple bar codes, only information from the last
scanned bar code will be included in the report. To view validator
parameters for all bar codes on a form, use the Online Data
Validator Data Manager software.
NOTE: If the label is not wide enough, not all of the information will
print.
The printed report is generated from validator reports received by
the printer during printing. The report does not include information
about bar codes that are placed in the validator scanning beam
while the printer is idle or from print jobs that generate an
“Unscannable: xx Missing Codes” error message.
The number of Total Scans and Good Scans can help you
determine if the print speed is set too high and causing borderline
failures by not allowing for enough scans to be done by the
validator. The Scan Report is based on the last Full Report received
by the validator. So if the last bar code printed is positioned close to
the last inch of the form, and on-demand printing occurs to force the
last bar code to be fed past the laser beam, the Total Scans and
Good Scans reported will not be the same as those reported by the
validator when printing at the set Print Speed (in the QUICK SETUP
and MEDIA CONTROL menus). This is because the on-demand
printing portion is done at a fixed print speed which may be higher
or lower than the set Print Speed. For example, a bar code printed
at 7 ips may yield eight Total Scans, but if printed in an on-demand
printing mode it may yield 18 Total Scans.

Chapter 2 Configuring The Validator
Beam Width
This menu item allows you to adjust the width of the scanning beam
to focus on specific areas where bar codes are expected. This will
reduce the amount of data the validator must process. Use this to
read bar codes near text or graphics that may interfere with the
validator if the text or graphics are scanned.
Reducing the beam width and focusing it to specific areas also
reduces light reflection interference to the validator from the media,
ribbon, tear bar, or other shiny surfaces.
You can set the Beam Width parameter to a value of 250 to 3100.
The default is 1800, 2550, or 3100 (4, 6, or 8 inch printers).
The higher the value, the wider the beam width.
NOTE: The Beam Width menu item will change the width of the
scanning beam but it is assumed that users will use the
Beam Shift menu item to move the beam to the correct
horizontal focus point.

Print Speed Limits
Operation
There are a number of factors which contribute to successful bar
code validation, including printer speed, on-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:
minimum code height (bar code height) and minimum code gap.
The printer automatically examines the Min. Code Height and Min.
Code Gap values and sets the defined maximum slew (vertical
paper movement) and print speeds to insure proper operation. If
the current Print Speed and/or Slew Speed values in the MEDIA
CONTROL menu are higher than the newly defined maximum, the
values are changed to equal the maximum. If the current values are
lower than the newly defined maximum, no change in speed
occurs.
Min. Code Height (Bar 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.
81

Use this formula to determine printer speed in relation to bar code
height:

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.
The default is 0.30 inches. The range is 0.15 to 1.00 inches in 0.01
inch increments.
Use this formula to determine printer speed in relation to minimum
code gap:
Min. Code Gap In Inches

83
Chapter 2 Operation
7. Press ↓ and ↵ at the same time to lock the ↵ key, then press
PAUSE to take the printer offline.
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.
On-Demand Printing
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 on-demand printing. In cases where
the bar code is close to the bottom of a label and the printer is in an
on-demand printing 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
on-demand printing 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.
84
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
described in “Validator Action (Error Action)” on page 86.
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
condition. How the printer then reacts is described in “Validator
Action (Error Action)” on page 86.
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.
•
You can set the number of bar codes generated by a
bitmapped image that the printer should expect per form by
selecting a value in the Number of Codes parameter.
85
Chapter 2 Bar Code Failures
For more information on choosing a value for the Number of Codes
parameter, see “Setting Number Of Bar Codes On A Form” on
page 56.
Validator Action (Error Action)
The printer response is the same whether the error stems from a
bad or missing bar code. It is determined by the Validator Action
setting in the VALIDATOR menu:
1. Press ... to take the printer offline and place the printer in
Menu mode.
2. If necessary, press ↓ and ↵ at the same time to unlock the
↵ key.
3. Press

7. Press ↓ and ↵ at the same time to lock the ↵ key, then press
PAUSE to take the printer offline.
8. Press PAUSE again to put the printer online.
86
Validator Action (Error Action)
Forms Printed After an Error Detection
Because of physical differences between the location of the
printhead and the scanning beam, one or more forms may print after
a bad form (a form with a bar code error that the validator detected).
The number of forms printed after a bad form depends on the Label
Length, Print Speed, and Slew Speed settings in the MEDIA
CONTROL menu. Shorter forms and faster speeds tend to increase
the number of forms printed before the validator has a chance to
detect an error. Also, the validator may not detect an error on forms
that have bar codes near the bottom of the form until the next form
has already started printing.
Forms that print after a bad form are treated differently, depending
upon the error action mode selected (see Table 5). Modes that
require a reprint operation may need to reprint more than just the
bad form.
Table 5. Actions Done to Forms That Print After A Bad Form

87
Chapter 2 Bar Code Failures
Stop
If the validator detects a bar code failure, the print job stops, the
printer status indicator lamp flashes, the alarm sounds, and the
appropriate error message displays.
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
with the form immediately following the bad form and any other
forms printed prior to the physical stop (see “Forms Printed After an
Error Detection” on page 87).
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 bad form. It then prints an obliterating pattern over the bad
form and any other forms printed prior to the physical stop (see
“Forms Printed After an Error Detection” on page 87). 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: Select Error Type Message to see the error message
printed on the bad form as the Overstrike Style.
IMPORTANT
If you are using an RFID encoder, set the validator Overstrike
Style different than the RFID Overstrike Style (in the RFID
CONTROL menu). This will help you differentiate between a
validator error and an RFID error.
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.
88
Validator Action (Error Action)
If more than one form is overstruck, only the first overstruck form is
lost (the one with the missing or bad bar code), and a separate print
command is required to resend it from the host, if needed. The rest
of the overstruck forms are automatically resent.
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
“Num Retry” on page 60.
The printer will stop, indicate an error, and overstrike as described
on page 88. Then it will skip a number of blank labels, depending
on the setting for Skip Labels (see “Setting For Skip Labels” on
page 58). It will then slew to the next top of a blank form and reprint
the bad form and any other overstruck forms (see “Forms Printed
After an Error Detection” on page 87).
Once the Num Retry counter has been exhausted, the print job
stops completely. After you clear the error message, the printer will
print the same label or the next label, depending on the setting for
Max Retry Action (see “Max Retry Action” on page 60).
Stop & Retry
This mode is similar to the Stop mode: the printer will stop printing
and display the error message. After you clear the error message, it
will then skip a number of blank labels, depending on the setting for
Skip Labels (see “Setting For Skip Labels” on page 58). Then it will
slew to the next top of a blank form and reprint the bad form and
any other forms printed prior to the physical stop (see “Forms
Printed After an Error Detection” on page 87).
NOTE: The number of times the printer will attempt to reprint the
bad form is determined by the Num Retry setting. See
“Num Retry” on page 60.
The printer will stop after the specified Num Retry attempts. After
you clear the error message, the printer will print the same label or
the next label, depending on the setting for Max Retry Action (see
“Max Retry Action” on page 60).
89
Chapter 2 Bar Code Failures
Grade&Report
In this mode, the entire print job will print uninterrupted. If one or
more errors is detected, the printer status indicator lamp flashes,
the alarm sounds, and the error message “Bar code fails / Job has
errors” displays.
IMPORTANT
The error message lets you know that at least one bad form
printed. To determine which form(s) are bad, you must
manually scan all of them.
The printer remains in a fault condition until you press the PAUSE
key. This clears the error message and takes the printer offline.
Correct any condition that may have caused the fault, then press
PAUSE to place the printer back online.
Rescan Form
This mode is similar to the Retry Form mode, however, instead of
backing up and overstriking the form, the printer will back up and
rescan the bad form and any other forms that have already printed
(see “Forms Printed After an Error Detection” on page 87).
NOTE: The number of times the printer will attempt to rescan the
form and following forms is determined by the Num Rescan
setting. See “Num Rescan” on page 60.
If the printer scans these forms correctly on any of the rescans, it
will continue printing with the next form.
If the printer fails to scan these forms correctly on all of the rescans,
it will overstrike the forms, stop, and indicate an error similar to Stop
mode. After you clear the error message, the printer will skip a
number of blank labels, depending on the setting for Skip Labels
(see “Setting For Skip Labels” on page 58).
It will then slew to the next top of a blank form and reprint the same
form or go the next form, depending on the setting for Max Retry
Action (see “Max Retry Action” on page 60).
NOTE: The only difference between Rescan Form and
Rescan&Stop is that when a form still fails after all the
rescans, Rescan Form will overstrike the bad form,
whereas Rescan&Stop will not.
90
Validator Action (Error Action)
Rescan&Retry
This mode is similar to Rescan Form with one exception: after the
printer has rescanned the form and overstruck it if there was still a
fault, it will reprint and rescan the same form again.
NOTE: The number of times the printer will attempt to rescan the
form is determined by the Num Rescan setting. See “Num
Rescan” on page 60.
The number of times the printer will attempt to reprint the
bad form is determined by the Num Retry setting. See
“Num Retry” on page 60.
If the printer scans these forms correctly on any of the rescans or
reprints, it will continue printing with the next form.
If the printer fails to scan these forms correctly on all of the rescans
and reprints, it will overstrike the forms, stop, and indicate an error
similar to Stop mode. After you clear the error message, the printer
will skip a number of blank labels, depending on the setting for Skip
Labels (see “Setting For Skip Labels” on page 58).
It will then slew to the next top of a blank form and reprint the same
form or go the next form, depending on the setting for Max Retry
Action (see “Max Retry Action” on page 60).
Rescan&Stop
This mode is similar to the Retry Form mode, however, instead of
backing up and overstriking the form, the printer will back up and
rescan the bad form and any other forms that have already printed
(see “Forms Printed After an Error Detection” on page 87).
NOTE: The number of times the printer will attempt to rescan the
form and following forms is determined by the Num Rescan
setting. See “Num Rescan” on page 60.
If the printer scans these forms correctly on any of the rescans, it
will continue printing with the next form.
If the printer fails to scan these forms correctly on all of the rescans,
it will stop and indicate an error similar to Stop mode. After you
clear the error message, the printer will skip a number of blank
labels, depending on the setting for Skip Labels (see “Setting For
Skip Labels” on page 58).
91
Chapter 2 Bar Code Failures
It will then slew to the next top of a blank form and reprint the same
form or go to the next form, depending on the setting for Max Retry
Action (see “Max Retry Action” on page 60).
NOTE: The only difference between Rescan Form and
Rescan&Stop is that when a form still fails after all the
rescans, Rescan Form will overstrike the bad form,
whereas Rescan&Stop will not.
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
selected error action (see “Validator Action (Error Action)” on
page 86) and show the appropriate error message on the printer
display. Validator error messages are explained in Table 6.
Table 6. Message List

Solution
1. Fix the application.
2. Disable Quiet Zone in
the VALIDATOR menu.
Typically, this occurs in forms
where bar codes are placed
too close to other elements,
the bar code is too close to an
edge of the media, or the
media’s position is shifting.
The minimum quiet zone on
each end of the bar code
should be ten times the
minimum element width or
1/4 inch, whichever is greater.
In addition, between bar
codes, the validator requires
a minimum distance of 20
times the minimum element
width or 1/2 inch, whichever is
greater.

1. Check that paper and
ribbon are clean,
unwrinkled, and
installed correctly.
2. Run a print job and
check that the validator
beam is not obstructed;
remove obstructions as
necessary.
3. Run a print job and
check that the READ
LED flashes as bar
codes exit the printer. If
the READ LED does not
flash, cycle power and
run the job again. If the
READ LED does not
flash, inspect the cables
and the cable
connections. If the
cables are undamaged
and the connections are
good, replace the
validator.
4. If using bitmapped bar
codes, set Number of
Codes (page 56) to the
number of codes per
form (not Auto).
5. Adjust Print Intensity
and Print Speed in the
QUICK SETUP menu or
via host software.

and then later removed.
1. Check that the validator
signal cable is securely
connected to the
validator unit.
2. Select Validator Funct.

Chapter 2 Troubleshooting
Troubleshooting
If you are having problems with the validator, consult Table 7 for a
list of symptoms and possible solutions.
Table 7. Troubleshooting the Validator
Symptom
The scanning beam does not
come on.
Solution
1. Make sure the power/data cable is plugged
into the validator and the controller board on
the printer. See “Installation and Removal”
on page 15.
2. Make sure the validator has not been
disabled in the VALIDATOR menu. See
“Enabling And Disabling The Validator” on
page 50.
3. Print a bar code validation demo page
(page 42).
4. Press the RESET button to turn the
scanning beam on (page 46).
5. Call your service representative if the
problem persists.
The scanning beam does not
cover the entire width of the
labels being printed.
1. Use Beam Shift to move the beam
horizontally to cover the entire width of the
labels. See “Shifting The Scanning Beam”
on page 39.
2. Use Beam Width to adjust the width of the
scanning beam. See “Beam Width” on
page 78.
The printer pauses after scanning
each label.
98
If you have an RFID encoder but are not
encoding RFID tags, make sure RFID Reader is
set to Disable (in the RFID CONTROL menu).
Table 7. Troubleshooting the Validator
Symptom
Solution
Printing 3 mil or 5 mil x-dimension
width bar codes constantly
causes error messages.
The validator does not recognize x-dimensions
as small as 3 mil or 5 mil. If you have to print bar
codes this size, disable the validator to prevent
error reports. See “Enabling And Disabling The
Validator” on page 50.
The printed labels look clean, but
the validator is still reporting an
error message.
The validator glass may be dirty, distorting the
report results. Power down the printer and clean
the glass using a household glass cleaner and a
dry, lint-free cloth.
The printed bar codes are
causing error conditions.
There are a number of factors which could be
causing validation errors:
•
The scanning beam is not properly aligned
with the two notches on the tear bar of the
printer. See “Adjust The Scanning Beam” on
page 33.
•
Make sure the entire bar code passes
completely under the scanning beam.
•
The validator and printer are not properly
communicating. Test the validator operation
without using a host. See “Bar Code
Validation Demo Page” on page 42.
•
Bar code width. The validator can recognize
x-dimensions as narrow as 6.6 mil for
300 dpi printers, and 10 mil for 203 dpi
printers. The validator cannot recognize
x-dimensions smaller than 6.6 mil or larger
than 40 mil.
•
Bar code size. A minimum height of 1/8 inch
is required for validation. If problems persist,
increase the bar code height.
99
Chapter 2 Troubleshooting
Table 7. Troubleshooting the Validator
Symptom
The printed bar codes are
causing error conditions.
(continued)
100
Solution
•
Bar code type. The validator only
recognizes the following linear, picket fence
bar codes: Codabar, Code 39, Code 93,
Code 128, Interleaved 2 of 5, and
UPC/EAN. Stacked, 2D, and vertical
(ladder) bar codes are not supported.
•
Bar code spacing.The validator requires a
minimum distance of 1/2 inch or 20 times
the minimum element width, whichever is
greater, between bar codes.
•
Printer speed. See “Print Speed Limits” on
page 81. If problems persist, decrease the
Print Speed in the MEDIA CONTROL menu.
•
Be sure the bar code is not printing on the
extreme edges of the label.
•
Clean the printhead. See “Cleaning” in the
User’s Manual.
•
Check that paper and ribbon are clean,
unwrinkled, and installed correctly.
•
Check the number of bar codes being
validated concurrently. The validator can
track the performance of up to four bar
codes at one time.
Maintenance
WARNING
Class 2 laser light. Do not stare into the laser beam or a
reflected image of the laser beam.
WARNING
Using controls, making adjustments, or performing
procedures other than those specified herein may result in
hazardous radiation exposure.
The validator is a self-contained unit that requires only periodic
cleaning. Every so often, power down the printer and use a
household glass cleaner and a dry, lint-free cloth to clean the glass.
If the problem with the printer is not fixed by one of these
troubleshooting methods, call your authorized service
representative or the Printronix Customer Support Center. See
