The service technician must save this log file to send it to the responsible service
or support center. This log file also contains the document reader serial number
and the firmware version number.
These two pieces of information are among the most important for tracking
problems. If the document reader cannot be operated (for example, due to a
defective power supply), then the service person must record the serial number
from the document reader´s back side manually.
Creating background images
The background correction images created during the factory calibration of the
device cannot be stored into the device. Therefore it is necessary to create
background images at the place of the intended operation for each D SCAN
AUTHENTICATOR CF device.
Creating background images is required when:
• A new or returned from service D SCAN AUTHENTICATOR CF device
will be installed at the place of operation.
• The computer where the D SCAN AUTHENTICATOR CF is connected will
be replaced by an other or a new one.
• You will operate a document reader, if it is returned from service. Replace
the previously used background images.
Preparation
Make sure that the following conditions exist before you perform the procedure.
• Clean the document contact area of the D SCAN AUTHENTICATOR CF
and allow the surface to dry. See “Cleaning” on page 5-1.
• Take the test chart from the product package and keep it in place.
• Power on the D SCAN AUTHENTICATOR CF and switch on your
computer.
• Start the D SCAN TestWizard and open the Image Acquisition page.
Procedure
Use the following procedure to capture and save background images.
1 Hold the test chart by the edges.
Note Do not touch the white side of the test chart.
