Color is patchy or distorted at the edges of the document.

The image is faint or out of focus.

Problem Solution

The document isn’t

positioned correctly on

the scanner’s

document table.

If the original is very thick or warped at the edges, the edges of the

image may be discolored. Cover the edges of the original with opaque

paper to avoid interference from outside light.

If part of the original is outside the document table, the edge may be

discolored. Change the position of the original.

Problem Solution

The document isn’t

positioned correctly on

the scanner’s

document table.

Make sure the document is placed flat on the document table.

Some EPSON TWAIN

Pro settings may be set

incorrectly.

Check your Tone Correction setting and/or select a darker Exposure

setting.

Your monitor isn’t

calibrated or isn’t

adjusted correctly.

Make sure you have calibrated your monitor to your scanner as

described in

Also check your

monitor’s brightness and contrast settings.
