Color Matching Problems
Colors on your monitor are different from those in the original 
image.
Try one or more of these solutions: 
❏Check the image settings of your scanner software, especially the data format (bits, 
pixel and color), gamma correction, and color correction. Try different combinations of 
these settings.
❏Check the color matching and color management capabilities of your computer, display 
adapter, and software. Some computers can change the color palette to adjust the 
colors on your screen. See your software and hardware manuals for details. 
❏Use the color management system for your computer: ICM for Windows, or ColorSync 
for Macintosh. For Windows, add a color profile that matches your monitor.
❏Exact color matching is very difficult. Check your software and monitor documentation 
for information on color matching and calibration.

❏The sealing tape might still be in the toner cartridge. Remove the toner cartridge, pull 
out the sealing tape, and reinstall the toner cartridge. See Replacing a toner cartridge

You may not be using the correct type of 
paper for copying.The available paper types for copying are not the 
same as that for printing. When you copy an original, 
use the correct type of paper. Depending on the 
paper source, the following paper types are 
available.
MP tray:
Plain paper, EPSON Color Laser Paper, Letterhead, 
Recycled paper, Colored paper, Transparencies, 
Labels 
Optional paper cassette:
Plain paper, EPSON Color Laser Paper, Letterhead, 
Recycled paper, Colored paper
Coated paper, thick paper, and special paper such 
as postcard or envelopes are not available for 
copying.
Cause What to do
The original is almost transparent or extremely 
thin.When you copy a thin double-sided original, the 
information on the back side of the original may be 
printed on the copy. Using black paper or an 
underlay beneath the original may solve the 
problem.
The copy setting may not be matched with 
the original.Select the settings that match the original and make 
a copy. When the settings are made correctly, the 
back side is not copied as the brightest part is 
adjusted to white. This also removes the yellowish 
color in the background.
If these problems cannot be solved even if the 
settings are made correctly, select Text for 
document type or set the contrast to a positive 
value.
