scan leaves a wide black mark the entire length of page

Scan leaves a wide black streak the entire length of the scanned page, which is very distracting and unprofessional in appearance.

Hello, @Greasetn - Hope you are well!

 

Thank you for becoming an HP Forum member. It is a great location to get help from the community, get suggestions and find what has worked for others 🙂

 

I understand you are getting vertical lines while scanning / copying using the Officejet printer. Are you getting this line while using the ADF as well as the scanner bed? Please try making a copy using the ADF and the Scanner bed and check.

 

Also, this issue is mainly caused due to ink / dirt on the ADF glass strip. Please try the below-mentioned steps to fix this issue:
 

  1. Make a blank copy using the ADF (if the issue is specific to ADF). Ideally, you should get a blank document with the vertical lines.
  2. Keep the output page on your flatbed / main scanner glass facing towards you.
  3. Follow the line or streak on the paper to the area on the ADF glass that is causing the issue. Thoroughly clean the thin “White ADF scanner lid strip” and the “Glass ADF scanner strip” using a lint-free wet cloth.
  4. Check the figure below. 3 is the Glass ADF strip & 2 is the White ADF scanner lid strip.
  5. If the issue is only with the scanner bed, then clean the scanner bed and the lid (4 & 1)

Those steps should do the trick, let me know the outcome.

Cheers 🙂
