Solving Problems
Solution
• Make sure the CX11N is turned on.
• Turn off the CX11N and your computer, and check the
connection between them.
• Make sure the CX11N is selected in your application software.
• In the Windows Device Manager menu, make sure CX11N
appears under Imaging devices hardware type without a
question (?) or an exclamation (!) mark, or as an Unknown
devices hardware type. If so, uninstall EPSON Scan, then
reinstall it following the instructions in your Setup Guide.
• For Windows users:
Double-click the Scanners and Cameras icon in the Control
Panel. Delete the CX11N icon and reinstall EPSON Scan as
described in your Setup Guide.
• Make sure your computer meets the system requirements on
page 131 and for the software you are using.
• Make sure the computer has enough memory for your
software. If it does not, see your software and computer
documentation for instructions on freeing up available memory
or upgrade your RAM.
Solution
• Make sure the document is placed on the document table with
the side to be scanned facing down.
• When scanning with the Black&White setting in Home Mode
or Professional Mode, adjust the Threshold setting.
Make sure the transportation lock on the left side of the
document table is set in the unlocked position.
Make sure the document is perfectly straight on the document
table. Align the vertical and horizontal lines with the scales at the
top and side of the document table.
