Scanner not scanning colors properly

[erniebird]

Hi, my photosmart 7520 isn't scanning true colors.  The color in the final scan isn't as bright.  Any tips on how to get the correct saturation?

Thanks!

Hey there! @erniebird, Thanks for stopping by the HP Support Forums! 

I understand you have scan quality issues with your printer.

Don't worry I'll try to help you out.

Did you make any changes to your printer?

Does the issue persist when you make a copy from your printer?

Have you tried scanning from a different application? Does the issue persist?

When does the issue persist when you scan from ADF or from the flatbed scanner?

As you mentioned when you scan from your printer scanner isn't scanning true colors. 

Try the steps recommended below.

Clean the automatic document feeder (ADF) rollers.

If your printer has an automatic document feeder (ADF), dust or paper residue on the rollers or separator pad inside the ADF can result in scan quality issues. Open the ADF, then clean the ADF rollers and separator pad.
   NOTE:
The location of the ADF rollers might be different depending on your printer, but the following steps still apply.
Gather the following materials:
A clean, lint-free cloth, or any cloth that does not come apart or leave fibers
Distilled, filtered, or bottled water (tap water might damage the printer)
Remove the original document from the ADF.
Turn off the printer.
Disconnect the power cord from the rear of the printer.
Open the ADF cover.
Find the paper pick rollers and the separator pad inside the ADF.
Lightly dampen a clean, lint-free cloth with filtered or distilled water, then squeeze any excess liquid from the cloth.
Use the damp cloth to wipe any residue off the paper pick rollers and the separator pad.
Leave the ADF cover open for two minutes to allow the paper pick rollers and separator pad to dry.
Close the ADF cover.
Reload the original document print side up in the document feeder tray. Gently slide the document into the printer as far as it can go.
Slide in the paper width guides until they are snug against the paper.
Do not push the paper width guides in so far that they bend the paper.
Reconnect the power cord to the rear of the printer.
Turn on the printer, then try to scan.
