Welcome to the HP support community.

I understand that you are getting scan quality issues, and I am glad to assist you.

Reset the printer

• Reset the printer to recover from printer errors or failures.
• If your printer has a rechargeable battery, remove it.
• With the printer turned on, disconnect the power cord from the printer.
• Unplug the power cord from the power source.
• Wait 60 seconds.
• Reconnect the power cord to a wall outlet and to the printer.
• NOTE:HP recommends plugging the printer directly into a wall outlet.
• Turn on the printer to complete the reset.

Clean the automatic document feeder (ADF)

• If your printer has an ADF, clean it regularly to help avoid paper jams and quality problems.
• Get a lint-free cloth and distilled water.
• Remove the original document from the ADF.
• Turn off the printer, and then disconnect the power cord.
• 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, and then squeeze any excess liquid from the cloth.
• Use the damp cloth to clean the paper pick rollers and the separator pad.
• Leave the ADF cover open for two minutes to allow the rollers and pad to dry.
• Close the ADF cover.
• Reconnect the power cord, and then turn on the printer.
