NOTE: When using a Document Scanner/Microimager 990S, you
are prompted to enter the calibration target once. When
using a Document Scanner/Microimager 990D, you are
prompted to enter the calibration target twice.
When calibration is successful, the status display returns to a normal
operating display.
If calibration is not successful, a message appears in the status
display.
You may need to:
•
Verify you are using a clean, blank sheet of paper as a calibration
target.
•
Verify there is not a document already in the document path. (Refer
to the section entitled, "Clearing the document path" in Chapter 7.)
•
Clean the Document Scanning Array. (Refer to the section entitled,
"Cleaning the Document Scanning Array" in Chapter 5.)
•
Calibrate the scanner/microimager again. If calibration fails again,
change the lamps. (Refer to the section entitled, "Replacing the
exposure lamps" in Chapter 5.)
If you have done all of the above and calibration still fails, contact your
service representative.
