Is the underside of the document cover/SPF/RSPF dirty?

00

 

Clean regularly.

 

 

 

 

 

 

Original smudged or blotchy?

00

 

Use a clean original.

 

 

 

 

 

 

Have you specified a suitable resolution?

00

 

Make sure that the resolution setting in the scanner driver is

 

 

appropriate for the original.

 

 

 

 

 

Are you scanning a large area (for example an entire 11" x

 

 

14") 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,

00

 

 

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.

 

 

 

 

 

Have you specified a suitable value for the "B/W

 

 

Threshold" setting?

 

 

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

 

 

 

using "Mono 2 gradation (no Green)","Mono 2 gradation (no

 

Poor scanning quality.

Red)" or "Mono 2 gradation (no Blue)" mode, make sure that a

00

 

 

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.

 

Are the brightness and contrast settings 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), activate the "Auto Brightness/Contrast

 

Adjustment" setting on the "Main" tab of the "Custom Settings"

 

 

screen. Click the "Brightness/Contrast" button to adjust the

00

 

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.

 

 

 

Have you placed the original straight?

00

Place the original straight on the original table.

 

 

 

Is the original placed in the correct position?

00

Place the original in the correct position.
