Calibrating the Scanner

2-2
You should calibrate the scanner:
• Once a day
• If image quality is poor
• After changing the lamps
NOTE: The Calibration function compensates for the varying
intensity of the scanner lamps which contribute to the
image quality of the scanned document.
Calibrate the scanner with a sheet of paper (calibration target) that
is:
• Blank
• Clean
• Matte (non-glossy finish)
• White or the same color as the background color of the docu-
ments you are going to scan
NOTE: When you are using a duplex-defined application mode,
make sure that both front and rear colors of the calibration
target correspond with the front and rear colors of the
documents to be scanned. If you are scanning a variety of
colored documents, use a white sheet of paper to cali-
brate the scanner.
• Wider than the documents you are going to scan. To scan 8.5 x
11 inch (216 x 279 mm) documents, the calibration paper should
be wider than 8.5 inches (216 mm).
To scan 11 x 17 inch (280 x 432 mm) documents, the calibration
paper should be wider than 11 inches (279 mm) but no wider
than 12 inches (305 mm).
• Between 12 inch (305 mm) and 25.5-inch (648 mm) long.
NOTE: For your convenience, 12" x 12" calibration targets are
supplied with the scanner and are also available from
Parts Services. (Refer to the Appendices in this manual
for ordering details.)
To calibrate the scanner:
1. Be sure the power switch is on, and initialization has com-
pleted.
2. Press the Cal key on the Control Panel. A message will
appear in the Status Display prompting you to feed the
calibration target.
3. Insert the calibration target into the feeder.
4. When the scanner calibration is successful, the Status
Display will return to its normal operating display (either
"Disabled" or "Enabled," depending on the status of the
scanner prior to calibration).
