The document glass or the underside of the document

 

 

cover/RSPF is dirty.

→ Clean regularly.

 

 

 

 

 

Original smudged or blotchy.

–

 

→ Use a clean original.

 

 

 

 

 

 

You have not specified a suitable resolution.

–

 

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

 

appropriate for the original.

 

 

 

 

 

You are scanning a large area (for example an entire A3)

 

 

at high resolution.

 

 

→ 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.

 

 

 

 

 

You have not specified a suitable value for the "B/W

 

 

Threshold" setting.

 

 

→ If you are scanning with a TWAIN-compliant application, make

 

Poor scanning quality.

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 "Professional" screen.

 

The brightness and contrast settings are not suitable.

→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 "Colour" tab of the "Professional"

–

 

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.

 

 

 

The original is not placed face up in the RSPF or face

 

down on the document glass.

→

Place the original face up in the RSPF or face down on the

 

 

document glass.

 

 

 

The original was not placed in the correct position.
