Calibration
The calibration procedures should only be performed by trained personnel. Therefore, the procedures are
defined separately. Contact your Printronix Service Representative or provider for more information.
Purpose of Calibration
Calibration is needed for the following three purposes:
•
To make sure the ODV-2D unit is functioning properly. This requires the use of a GS1 calibration
plaque that was supplied with your unit.
•
To make sure the ODV-2D unit is aligned properly with the printer. The ODV-2D unit is connected
via a bracket and fine tuning may be required if the unit is bumped or transported to another
location.
•
To make sure the ambient lighting conditions are considered when grading barcodes.
Validation Demo Page
The 2-D bar code validation demo page allows you to test or demonstrate proper validator operation
without a host computer. This page contains several bar code symbologies (including 2-D) and is
recommended for 4x6 labels.
NOTE:
If the menu
Media > Image > Label Width
or
Media > Image > Label Length
or
Media > Image >
Label Width
is
set to something other than 4” or 6”, respectively, then some of the barcodes may
not print. This does not invalidate the test, but does not allow the entire scan width to be verified. If
Label dimensions are too small, no barcodes will be printed.
To print and validate the bar code validation demo page:
1. Load the factory default configuration. (Refer to the
Administrator
’s Manual
.)
2. Set
ODV-2D > Control > Validator Active
to
“
Enable
”
.
3. Set
Sensors > Control > Gap/Mark Sensor
to
“
Gap
”
.
4. Load media.
5. Using
Sensors > Calibrate > Auto Calibrate
or by selecting
in the Home screen, run Auto
Calibrate for proper gap sensing.
6. Edit the menu
Tools > Print Tests > Run Tests
. If the panel is locked, press the UP+DOWN ARROW
keys simultaneously to unlock.
7. Find the printer test named
“
Barcode Demo 2D
” and press the ENTER key.
8. The printer will return ONLINE automatically and print one demo page.
9. To demonstrate a bad bar code reading, block the scanning beam with an opaque object while the bar
code moves under the beam. When you block the beam, the ODV-2D will generate a reading error and
will perform a default error action. The default setting for
ODV-2D > Control > Validator Action
is
“
Retry
Form
”
. Using the factory default settings, the printer will pull the label with the bad barcode back,
overstrike the entire label, reprint the barcodes on the next label, and then stop.
10. Press the PAUSE key to take the printer OFFLINE.
11. Lock the panel again using the UP+DOWN ARROW keys.
12. Press the PAUSE key to place the printer back ONLINE.
