Your scanned image is blurred or 
distorted.
■Check the position and condition 
of your document. Make sure it is 
placed flat against the document 
table glass. If only part of the 
image is blurred, part of your 
document may be wrinkled or 
warped. 
■Make sure the document table 
glass is clean.
■Make sure you didn’t accidentally 
move the document during 
scanning.
■Make sure the scanner is on a flat, 
stable surface.
The edges of the document aren’t 
scanned.
■Don’t place your document right 
up against the edges of the 
document table. Move the 
document about a quarter of an 
inch away from the edges.
■If colors are patchy or distorted at 
the edges of the image, the 
document may be too thick, or 
there may be outside light 
interfering with the scan. If you are 
scanning without the cover, place 
paper over the edges of the 
document to block outside light. 
						

							62Solving Problems
Your image scans at an angle.
Check the position of your document. 
It may be placed at an angle on the 
document table. Align it so the 
horizontal and vertical edges are 
carefully aligned with the scales on the 
top and side of the document table. 
Straight lines in the image come out 
jagged.
Make sure the document is aligned 
with the scales on the top and side of 
the document table. 
Your image is too dark.
■Increase the brightness setting in 
EPSON Scan Office or Home 
Mode.
■Select Professional Mode and 
adjust the exposure using the   
Auto Adjust button. 
■Select Professional Mode and 
adjust the Gamma setting using 
the   Histogram Adjust button. 
■Try different combinations of 
gamma and color settings in 
EPSON Scan. Click the 
Configuration button at the 
bottom of the window, then make 
any changes on the 
Color tab. 
■Change the Destination setting in 
the Home or Office Mode.
A line of dots is missing from the 
image.
■When a line of dots is missing 
from the scanned image on your 
screen, the scanner sensor has 
malfunctioned. Contact Epson.
■When a line of dots is missing 
from your printouts, your printer 
has malfunctioned. See your 
printer manual. 
						

							Solving Problems63
The colors in your scanned image 
look different from the colors in the 
original document.
■Make sure the Image Type setting 
in EPSON Scan is correct.
■Try different combinations of 
gamma and color settings in 
EPSON Scan. Click the 
Configuration button at the 
bottom of the window, then make 
any changes on the 
Color tab. 
■Exact color matching is difficult. 
Check your software and monitor 
documentation for information on 
color matching and calibration.
Moiré (cross-hatch) patterns appear 
in the scanned image.
■Make the image size slightly 
smaller.
■In EPSON Scan, select the 
Descreening Filter checkbox. If 
you’re using Professional Mode, 
you may have to scroll to see this 
setting.
■In Professional Mode, set the 
Screen Ruling to the appropriate 
setting for your document. 
■Use a transparent sheet between 
the document and the document 
table to defocus the image slightly.
■Reposition the document on 
the document table. Try 
positioning the document at a 
slight angle.The printed image is larger or 
smaller than the original.
You can’t judge the size of the printed 
image by what you see on your screen. 
The image size settings in your scanner 
software determine the size of the 
printed image. Check the Target Size 
setting in EPSON Scan.
The image doesn’t scan, or you get 
only a few dots for the scanned 
image.
■Make sure the document is face 
down on the document table.
■If you’re using the automatic 
document feeder, make sure the 
original document is inserted 
face up.
■Select Black&White for the Image 
Type and change the Threshold 
setting.
The file size is too big. 
Adjust your scan settings. Try setting 
at a lower resolution (dpi), or scan 
only part of the image.
Poor character recognition during 
OCR scanning.
Adjust the Threshold setting.
