If you get poor quality as a result of scanning a job, and you cannot improve the quality by changing preferences, refer 
to the check list shown below.
CHECK1
Is the original clean?
Check your original before scanning. If any dust 
sticks to the original, you cannot obtain a clean 
result. In addition, make sure that the original table 
is also clean.
CHECK2
Have you specified a suitable resolution?
Make sure that the value for the "Resolution" setting 
in the scanner driver satisfies the requirement of the 
set original.
Reference:
Scanning an Image from a TWAIN-
Compliant Application
Scanning an Image from a WIA-Compliant 
Application (Windows XP)
Scanning an Image from the "Scanner and 
Camera Wizard" (Windows XP),
CHECK3
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 Red)" or "Mono 2 
gradation (no Blue)" mode, make sure that a 
suitable value is specified for the "B/W Threshold" 
setting. A larger threshold value makes your output 
darker, whilst 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.

Compliant Application
CHECK4
Have you adjusted the brightness and 
contrast suitably?
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 brightness and the contrast 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.
If part of the image from the back side of the original
appears in the preview scan.
If you are using a TWAIN-compliant application and 
the back side of the original appears faintly in the 
preview image, try adjusting the Brightness and 
Contrast settings.
Click the 
"Brightness/Contrast" button
 in the 
Preview screen to change to the Brightness/
Contrast screen, and adjust the "Brightness" and 
"Contrast" values. A preview of the image using the 
new values appears under "After". When the image 
of the back side disappears and you can get only 
the needed image, click the "Apply" button to apply 
the new setings, and then click the "Scanning" 
button to scan the image.

If you cannot scan the image, turn off your computer. Press the power switch on the unit to turn it off, unplug the unit from the power 
source, and then plug it back in. Restart your computer. Try scanning again. If scanning is still not possible, refer to the check list below.
CHECK1
Is your application compliant to TWAIN?
If you are using Windows 98/Me/2000 and your application 
is not TWAIN compliant, the application cannot acquire 
images. Use an application that is TWAIN compliant, such 
as the included Sharpdesk.
CHECK2
Have you selected the scanner driver of this 
unit on your application?
Make sure that the "SHARP Personal MFP series" or "WIA-
SHARP AL-XXXX" is selected on your application.
Reference:
Scanning an Image from a TWAIN-
Compliant Application
CHECK3
Have you specified all scanning preferences 
appropriately?
Setting a large area with full color together with a high 
resolution setting, makes the data size large, resulting in 
extended scanning times. It is recommended to set the 
scanning preferences depending on the type of original to 
be scanned, i.e., Text, Text/Graphics, Photograph, Color, 
Black & White.
CHECK4
Is there enough computer memory?
Your computer may not have enough available memory to hold 
the document you want to scan. Lower the scan resolution.
CHECK5
Has the specified period of program timeout 
already elapsed?
Neither printing nor scanning jobs can be sent to the unit 
from your computer during the specified period of program 
timeout after copying.
To send a printing or scanning job immediately, press the 
clear 
(
key
 
on the unit twice to clear all the settings for 
the unit.
Reference:
For more detail, refer to "USER 
PROGRAMS" in the Operation Manual.
CHECK6
Are you trying to scan multiple originals in the 
SPF/RSPF at once?
When multiple originals are loaded in the SPF/RSPF, it 
depends on your application whether only one original can 
be scanned in a single operation, or whether multiple 
originals can be scanned. Check which is possible in your 
application. (Sharpdesk allows multiple originals to be 
scanned in a single operation.)
CHECK7
Does your computer's operating system 
support the scanner driver?
The operating systems that support the unit's scanner driver 
are Windows 98/Me/2000/XP.
CHECK8
Are you using an appropriate interface?
Only the USB interface can be used for the unit's scanning 
function. Make sure the unit is connected to your computer 
with a USB cable. If the unit was connected to your 
computer with a parallel cable when you installed the 
SHARP Personal MFP series software, uninstall the 
SHARP Personal MFP Series software. Refer to 
"INSTALLING THE SOFTWARE" in the Operation Manual 
for the order of installation of the SHARP Personal MFP 
series software and connection of the USB cable, and 
reinstall the SHARP Personal MFP series software.

CHECK9
Have the scanner driver and Button Manager 
been installed properly?
If normal scanning still cannot be performed even after 
confirming the items on the above check list, delete SHARP 
Personal MFP series software and then reinstall it.
