HP Officejet 7610 - Scanned image quality is poor

Scanned image quality is poor

The original is a second-generation photo or picture

Reprinted photographs, such as those in newspapers or magazines, are printed by using tiny

dots of ink that make an interpretation of the original photograph, which degrades the quality.

Often, the ink dots form unwanted patterns that can be detected when the image is scanned or

printed or when the image appears on a screen. If the following suggestions do not solve the

problem, you might need to use a better-quality version of the original.

To eliminate the patterns, try reducing the size of the image after scanning.

Print the scanned image to see if the quality is better.

Make sure that the resolution and color settings are correct for the type of scan job.

For best results, use the scanner glass for scanning rather than the ADF.

Text or images on the back of a two-sided original appear in the scan

Two-sided originals can "bleed" text or images from the back side to the scan if the originals

are printed on paper that is too thin or too transparent.

The scanned image is skewed (crooked)

The original might have been loaded incorrectly. Be sure to use the paper guides when you

load the originals into the ADF. For more information, see Load an original in the automatic

document feeder (ADF) on page 15.

For best results, use the scanner glass for scanning rather than the ADF.

The image quality is better when printed

The image that appears on the screen is not always an accurate representation of the quality of

the scan.

Try adjusting your computer monitor settings to use more colors (or levels of gray). On

Windows computers, you typically make this adjustment by opening Display on the

Windows control panel.

Try adjusting the resolution and color settings.

The scanned image shows blots, lines, vertical white stripes, or other defects

If the scanner glass is dirty, the image produced does not have optimum clarity. See

Maintain the printer on page 22 for cleaning instructions.

The defects might be on the original and are not a result of the scanning process.

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 scanner glass to scan rather than the ADF.

Use high-quality originals.

Place the paper correctly. If the paper is placed incorrectly on the scanner glass, it might

skew, which causes unclear images. For more information, see Load an original on the

scanner glass on page 14.

Adjust the HP 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. For more information, see Clean the scanner glass on page 22.
