Hi @Solty,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
I'm really sorry to hear you're still having trouble with paper jams on your HP Smart Tank 5105 All-in-One Printer—it sounds incredibly frustrating, especially after trying all the usual fixes. I understand how important it is to have a reliable printer, and I'd like to help you work through some additional troubleshooting steps:
1. Verify Paper Quality and Loading:
- Ensure you're using paper that meets HP's recommended specifications.
- Double-check that the paper is properly aligned in the tray and that the paper guides are snug but not too tight.
2. Clean the Paper Feed Rollers:
- Turn off the printer and unplug it for safety.
- Gently clean the feed rollers using a lint-free cloth lightly dampened with water (or the cleaning solution recommended by HP).
- Allow the rollers to dry completely before turning the printer back on.
3. Inspect the Paper Path for Obstructions:
- Open all accessible areas of the paper path and look for any debris, torn paper fragments, or foreign objects that might be causing the paper to catch.
- Use a flashlight to carefully examine less-visible areas.
4. Check for Worn or Damaged Rollers:
- Sometimes rollers can wear out over time. Inspect the rollers for any signs of damage or excessive wear.
- If the rollers appear worn or damaged, they might need to be replaced, and contacting an authorized service center would be advisable.
5. Update Firmware:
- Visit the HP Support website to check for any available firmware updates for your HP Smart Tank 5105.
- Installing the latest firmware can sometimes resolve issues related to paper feeding.
6. Perform a Hard Reset:
- Turn off the printer, unplug it, and wait for about 60 seconds.
- Plug it back in, then power it on again to see if this clears the persistent issue.
I hope this helps.
Take care and have a good day.
