7. If you selected the TIFF6.0(JPEG) or JPEG format, EPSON

Scan! II allows you to choose the image quality. Since JPEG

is a Lossy compression scheme, selecting higher quality

gives you less compression. To choose the image quality,

move the

Quality

slide bar to the desired setting.

8. Choose OK.
