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.19
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.
16

You have not specified a suitable resolution.
→Make sure that the resolution setting in the scanner driver is 
appropriate for the original.–
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.

Unable to scan the image.Your application is not TWAIN compliant.
→If your application is not TWAIN compliant, scanning will not be 
possible. Make sure your application is TWAIN 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-compliant application.–

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.–
The recipient does not receive a 
transmitted data.There is a mistake in the stored destination information 
or the wrong destination was selected.
