Calibration
Target
Calibration sets the intensity of the lamps, which contribute to the overall
quality of the scanned document image.
The Scanner should be calibrated:
• At least once a day when the Scanner is turned on using the Side
Panel Switch - prior to scanning documents.
• Any time the Scanner is turned on using the Main Power Switch.
• If image quality is poor.
• After changing lamps.
Calibrate the Scanner using a calibration target (sheet of paper) that is:
• Blank.
• Clean.
• Matte finish (not glossy).
• White or the same color as the background color of the documents to
be scanned. If you are scanning a variety of colored documents, use
a white calibration target.
• Wider than the documents you are going to scan (i.e. to scan 8.5 x 11
inch (215.9 x 279.4 mm) documents, the calibration target should be
wider than 8.5 inches/215.9 mm). The recommended width for the
calibration target is 12 inches (300 mm).
1. Verify that the Main Power Switch (located at the rear of the
Scanner) and Side Panel Switch are on. A normal operating Status
Display should appear.
2. Press P-Key P1 or enter Function Code F37 to initiate the
calibration sequence.
3. Insert the calibration target into the feeder.
When the calibration is successful, the Status Display will return to a
normal operating display.
