The printed image is light and 
uneven.The paper is loaded so that printing takes place on the 
back side of the paper.
→Some paper types have a front and back side. If the paper is 
loaded so that printing takes place on the back side, toner will not 
adhere well to the paper and a good image will not be obtained.10
The printed image is dirty.You are using paper that is outside the specified size and 
weight range.
→Use copy paper within the specified range.

Paper curled or damp.
→Do not use curled or crimped paper. Replace with dry copy paper. 
During periods when the machine is not used for a long time, 
remove the paper from the tray and store it in a dark place in a 
bag to prevent moisture absorption.
–
You did not set sufficient margins in the paper settings of 
your application.
→The top and bottom of the paper may be dirty if the margins are 
set outside of the specified print quality area.
→Set the margins in the software application within the specified 
print quality area.–
The printed image is skewed or it 
runs off the paper.The paper loaded in the tray is not the same size as that 
specified in the printer driver.
→Check if the Paper Size options suit the size of the paper loaded

cover/SPF/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 
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.

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

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 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.–
There is not enough machine memory.
→The scan resolution will vary depending on the scanning area and 
how much memory in the machine is free.–
Scanner transfer speed is slow.Your computer does not meet the system requirements 
for the USB 2.0 interface (Hi-Speed mode).
