appropriate for the original.–
You are scanning a large area (for example an entire 11 x 
17) 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 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.

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 
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.

Quick Scan has been selected.
→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.)

Unable to scan the image.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 in full color at high resolution results in a 
large amount of data and extended scanning times. The scanning 
preferences should be set appropriately for type of original to be 
scanned, i.e., Text, Text/Graphics, Photograph, Color, or Black & 
White.
–
There is not enough computer memory.
→The scan resolution will vary depending on the scanning area and 
how much memory in the machine is free. To can a 11 x 17 
original in full color at 600 dpi without using enhancement, the 
dual function board and the 256 MB optional memory (AR-SM5)  
are required.

You do not have Administrator rights.
→To use the machine to scan into Windows 2000/XP, you must log 
on as an Administrator.–

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

Notice page printed
If you find that a notice page has been printed at the end of a print job, the print data received from the computer has 
not been printed as specified. Fix the problem as explained below and then try printing again.
What to do when a notice page is printed, 1
The above notice page is printed if you attempt to print 
using the print driver for the dual function board when 
the dual function board is not installed. Change to the 
standard print driver and print again. If the standard 
print driver is not installed, install as explained in the 
Software Setup Guide.
What to do when a notice page is printed, 2
The above notice page is printed when a print job 
containing more data than can be held in the memory 
of the dual function board is sent to the machine. To fix 
the problem, disable the ROPM function. If you need to 
use the ROPM function, set the print quality in the 
printer driver to Draft, or increase the amount of 
memory on the dual function board.
