Faint Blue line on my scanned pdf documents

[Spar48]

I purchased this printer several months ago, and just recently it has developed a problem while scanning. Every time a page is fed through the document feeder, the scan has a light blue line lengthwise down the scanned PDF page. What is the cause and how can it be fixed. Please help!

@Spar48, Welcome to HP Support Community!

I see that you have issues while scanning from the document feeder, follow the steps below-

Clean the plastic and glass strips inside the document feeder with a soft, lint-free cloth sprayed with glass cleaner.

NOTE: 

Some printers ship with a document feeder cleaning cloth. If you have the cloth, load it into the document feeder and start a copy job to clean the scanner mechanism.

1. Turn the printer off, disconnect the power cord, and then remove the battery if your printer has one.

2. Depending on your printer model, open any top cover, document feeder tray, and scan document feeder cover.

3. Look for and remove any dust or debris from inside the document feeder.

4. Spray a soft, lint-free cloth with glass cleaner, and then wipe the scanner glass and the white strip on the underside of the document feeder until clean, dry, and streak-free.

      CAUTION: 

   To protect the interior printer parts, do not spray the cleaner directly on or into the printer.

5. Securely close any covers and trays that you opened.

6. Reconnect the power cord to the printer, and then try making a copy.

Additonally, Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

Refer to the document HP Printers - Resolving Copy Problems for more help.

Hope this helps! Keep me posted.
