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.
