Problem

Poor scanning

quality.

Unable to scan the

image.

Scanner transfer

speed is slow

when the dual

function board is

installed.

Cause and solution

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 [Color] tab of the "Custom Settings (or Professional)" screen.

You can also 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.

[Quick Scan] has been selected. (With the dual function

board installed)

→ If scanning is performed when [Quick Scan] has been selected in the

[Preference] tab of the "Custom Settings (or Professional)" of the

TWAIN driver, 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. (By default [Quick Scan] is not selected.)

The original is not placed face up in the SPF or face down

on the document glass.

→ Place the original face up in the SPF or face down on the document

glass.

The original was not placed in the correct position.

→ Place the original correctly.

If scanning is not possible, shut down your computer,

turn off the machine's power switch, and unplug the

machine's power cord. Next, start your computer, restore

power to the machine, and try scanning again. If scanning

is still not possible, check the following items.

Your application is not TWAIN/WIA compliant.

→ If your application is not TWAIN/WIA compliant, scanning will not be

possible. Make sure your application is TWAIN/WIA compliant.

You have not selected the scanner driver of the machine

in your application.

→ Make sure that the machine's scanner driver is selected in your

TWAIN/WIA-compliant application.

You have not specified all scanning preferences appropriately.

→ Scanning a large area at high resolution results in a large quantity of

data and a prolonged scanning time. When selecting the scan

preferences, lower the resolution or specify a suitable scanning area.

"DISABLE USB SCAN" has been enabled in the key

operator programs.

→ Consult the key operator.

Make sure that your computer meets the system

requirements for the USB 2.0 interface (Hi-Speed mode).

→ Make sure that your computer meets the system requirements

described in "System requirements for USB 2.0 (Hi-Speed mode)" in

the "Key operator's guide", and then set "USB2.0 MODE" to

"HI-SPEED" in the key operator programs.
