Graphics look different from the original

Scan at a higher resolution.

NOTE: Scanning at high resolution can take a long time, and it can take up a large amount of space on your computer.

Take steps to improve the scan quality

◦Use the glass to scan rather than the ADF.

◦Use high-quality originals.

◦Place the media correctly. If the media is placed incorrectly on the scanner glass, it might skew, which causes unclear images. For more information, see Load the originals.

◦Adjust the software settings according to how you plan to use the scanned page.

◦Use or make a carrier sheet to protect your originals.

◦Clean the scanner glass. See Clean the scanner glass for more information.

◦Try adjusting the settings. Be sure to use the correct resolution and color settings.

◦The original image might be very light or dark or might be printed on colored paper.

•Unwanted lines

Ink, glue, correction fluid, or an unwanted substance might be on the scanner glass. Try cleaning the scanner glass. See Clean the device for more information.

•Black dots or streaks

◦Ink, glue, correction fluid, or an unwanted substance might be on the scanner glass; the scanner glass might be dirty or scratched; or the lid backing might be dirty.
