Hello,
I have an HP 4632 printer.
When I scan a line appears like a hair from top to bottom down the scanned page. This is only when using the automatic paper feeder for scanning. Is there a way to clean the roller of mechanism?

Hello @Zone123 – 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 facing lines while scanning / copying using the ADF. Please try the below-mentioned steps to fix this issue.
- Make a blank copy using the ADF. Ideally, you should get a blank document with the one vertical line.
- Keep the output page on your flatbed / main scanner glass facing towards you.
- 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.
- Check the figure below. 3 is the Glass ADF strip & 2 is the White ADF scanner lid strip.

Let me know how that goes. I’ll watch for your reply!
Good luck 🙂
