HI @HaroldMB,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If you’re experiencing black lines down your printouts when using the auto-feed function on your HP printer, this typically indicates an issue with the printer’s paper feed mechanism or the imaging components. Here’s a step-by-step guide to diagnose and fix this problem:

1. Check for and Clean Paper Path Rollers

Turn Off and Unplug:

• Ensure the printer is turned off and unplugged to avoid any risk of electric shock or damage.

Inspect Paper Path:

• Open the paper tray and any accessible areas where paper passes through.

Clean Rollers:

• Use a soft, lint-free cloth lightly moistened with water (not soaked) to clean the paper feed rollers. Gently wipe the rollers to remove any dust or debris that might be causing feeding issues.
• Allow the rollers to dry completely before closing the printer and plugging it back in.

2. Check the Toner or Ink Cartridge

Remove and Inspect Cartridge:

• Remove the toner or ink cartridge(s) from the printer.

Check for Spills or Leaks:

• Inspect the cartridge and its area for any signs of toner or ink leaks. A leaky cartridge can cause black lines.

Clean Cartridge:

• Wipe the cartridge with a soft, dry cloth to remove any toner or ink residue.

3. Perform a Printer Calibration

Access Printer Calibration:

• Many HP printers have a calibration or alignment feature available through the printer’s control panel or printer software.

Run Calibration:

• Follow the printer’s menu options or software instructions to run a calibration or alignment process. This can help correct printing issues related to alignment and quality.

4. Inspect and Clean the Imaging Drum

Remove Imaging Drum:

• If your printer has a removable imaging drum, carefully remove it according to the printer’s manual.

Clean the Drum:

• Gently wipe the drum surface with a dry, lint-free cloth. Avoid touching the drum with your fingers, as this can damage it.

Reinstall the Drum:

• After cleaning, reinstall the drum and ensure it is seated properly.

5. Check for Paper Quality Issues

Use Proper Paper:

• Ensure you are using the correct type and size of paper recommended for your printer. Poor-quality or incorrect paper can cause printing issues.

Avoid Paper Buildup:

• Make sure there is no paper buildup or debris in the paper tray or feed area.

6. Run Printer Diagnostics

Use Printer Tools:

• Use any built-in diagnostic tools available through your printer’s control panel or HP printer software to identify and troubleshoot issues.

Check for Firmware Updates:

• Visit the HP Support website to check for any firmware updates for your printer model. Updating firmware can resolve bugs and improve printer performance.

I hope this helps.

Take care and have a good day.
