• 600-dpi optical resolution for high-precision image scanning
Scanning with an optical resolution of 600 dpi allows even complex and difficult-to-scan documents,
such as CAD drawings, electronic files, and mapping data to be scanned rapidly and with high precision.
Scanning Master 21+ (scanner software included as a standard accessory) can be used to adjust the
resolution in five levels (50 dpi to 800 dpi/50 dpi to 4800 dpi, in 1-dpi increments) to suit the scanned
document.
• Compatible document widths range from 210 mm to 1066 mm
Compatible with document sizes from ISO A4 up to ANSI E (42 inches)
• Capable of color and grayscale scanning
Capable of scanning in color (24-bit color, 8-bit color) or grayscale (256 shades)
• Support of automatic thickness detection
ITA (Intelligent Thickness Adjustment) supports automatic document-thickness detection.
• Capable of reading long-axis data
Scanning of long-axis images is supported.
• Compact and lightweight design
A compact design was achieved by using a document travel system that employs contact image sensors
in the sensor unit (five rows arranged in a zigzag pattern).
• Image-processing functions
Use of the scanning software provided lets you set image-processing functions for the scanning of a
document.
• Interface

CS600-UM-251-9370 4-2
4. DAILY MAINTENANCE
Transparent contact plates

4.3 Cleaning the Image Sensors

The scanner’s image quality drops when the transparent contact plates over the image sensors become dirty,
so clean the image sensors whenever necessary.
Procedure
(1) Turn off the scanner.
(2) Open the top cover as described in Section 4.1 “Opening and Closing the Top Cover”.
(3) As shown below, wipe off any soiled areas on the transparent contact plates using a soft cloth that has
been moistened with water or a neutral detergent (diluted with water) and firmly wrung out.
(4) Completely remove any moisture on the transparent contact plates by wiping them off again using a
soft, dry cloth.
(5) Close the top cover as described in Section 4.1 “Opening and Closing the Top Cover”.
Take care not to get your fingers caught in the cover.
Do not use a commercial cleaner for office equipment, a glass cleaner, or chemical solvents such as solutions con-
taining alcohol.
Although the glass scanning table is not a maintenance part that requires periodic replacement, it is a consumable
part because its surface may receive slight scratches due to minute particles of dust and other foreign matter. If
document scanning produces unsatisfactory results (unexpected white or black streaks in the data) due to scratch-
es on the glass table or other reasons, please perform the calibration procedure (see Section 4.6, “Calibration”). If
the scanning results do not improve after calibration, the glass table will need to be replaced.

4.6 Calibration

Calibrate the scanner if scanning quality is observed to deteriorate, with scanned results such as those
described below:
• The scanned image is distorted
• Areas of uneven color appear in the scanned image
• Other unsatisfactory results (but not including problems related to media quality, such as folds, wrinkling, or
paper curling)
• Handle the calibration sheet with care so that it does not get bent. To prevent soiling, store it in its special storage
box. The calibration sheet cannot be used if it is bent or soiled.
• The calibration sheet is a paper product. Do not attempt to clean it with any type of liquid cleaner.
• The calibration sheet is a consumable item. Replacement sheets can be purchased from your sales representative
or nearest Graphtec vendor.
Preparation and checks
Recommended usage environment
• Monitor: 1024 x 768 pixels, High Color or better resolution
A low-resolution monitor will make it difficult to discern any problem areas.

(10) To check the calibration results, click the Confirm button in the Calibration menu (shown in step (5)
above).
(11) The following message is displayed. Insert the calibration sheet into the scanner as instructed.
(12) Click the OK button to start scanning.
The scanned data is displayed when scanning is complete. Colors may differ slightly for individual
sensors to make it easier to identify problem areas in calibration. This does not indicate a defect.
Check that there are no vertical streaks, such as white patches, in the scanned data.
(Streaks occur when calibration is not performed correctly due to contamination by dust or dirt.)
(13) If the data is normal, calibration is complete.
Click the Close button and exit the Scanner Adjustment Program.
(14) If any abnormal data is observed, specify the problem areas as follows:
Select Specified Part in Calibration.
(15) The mouse arrow cursor changes to a cross cursor when moved over the data. Click the left mouse
button with the mouse positioned over the streak data. The selected area is shown in blue. Repeat this
procedure for any additional streaks.
Areas that have been selected (shown in blue) can be deselected by clicking the left mouse button
again. To deselect all selected areas, click the Clear button.
(16) Once all required areas have been specified, remove the calibration sheet and clean the glass and table
surfaces. Check the calibration sheet for dust and dirt, then click the Execute button.
(17) Return to step (10) and verify the calibration results.
