→ Clean regularly.

72

→ Use a clean original.

–

→ Make sure that the resolution setting in the scanner driver is 

appropriate for the original.

–

→ If you attempt to scan a large area at high resolution and there is 

insufficient memory in the machine to hold the scanned data, 
scanning will take place at a lower resolution and the scanner 
driver will enhance the data to make up for the lower resolution. 
However, the quality of the enhanced image will not be as high as 
if scanning took place at the higher resolution. Use a lower 
resolution setting, or scan a smaller area.

–

→ If you are scanning with a TWAIN-compliant application and are 

using "White", "Red", "Green" or "Blue" mode from "Light Source" 
menu, make sure that a suitable value is specified for the "B/W 
Threshold" setting. A larger threshold value makes your output 
darker, while a small threshold value makes it lighter. To adjust 
the threshold automatically, click the "Auto Threshold" button on 
the "Image" tab of the "Custom Settings" screen.

–

→ If you are scanning with a TWAIN-compliant application and the 

resulting image has unsuitable brightness or contrast (for 
example it is too bright), click the "Auto Brightness/Contrast 
Adjustment" button on the "Color" tab of the "Custom Settings" 
screen. Click the "Brightness/Contrast" button to adjust the 
brightness and the contrast while viewing the scanned output 
image on the screen. If you are scanning with a WIA-compliant 
application or the "Scanner and Camera Wizard", click "Adjust 
the quality of the scanned picture" or the "Custom settings" 
button, and adjust the brightness and contrast in the screen that 
appears.

–

→ Place the original face up in the SPF/RSPF or face down on the 

original table.

18, 19

→ Place the original correctly.

→ If scanning is performed when the "Quick Scan" option has been 

selected, image quality may be degraded. This is because the 
scanned data is transferred using JPEG compression. If image 
quality is poor, then perform scanning again without selecting the 
"Quick Scan" option. ("Quick Scan" is not selected by default.)
