Hi @Roderos,

 

Welcome to HP Support Community.

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

 

Horizontal lines on printouts from your HP LaserJet Pro MFP M281fdw can be caused by several issues. Here’s a step-by-step guide to diagnose and resolve the problem:

1. Check the Toner Cartridges

  • Inspect Toner Cartridges: Open the toner cartridge compartment and ensure that the cartridges are properly seated.
  • Remove and Reinstall: Carefully remove and reinstall the cartridges to ensure they are seated correctly.
  • Check for Damage: Look for any physical damage or defects in the toner cartridges.

2. Examine the Drum Unit

  • Inspect Drum: The drum unit is responsible for transferring toner onto the paper. Check it for any damage or wear.
  • Clean Drum: Gently clean the drum with a soft, dry cloth if it appears dirty. Avoid using liquids or abrasive materials.

3. Perform a Printer Calibration

  • Calibration: Run a calibration or alignment procedure from the printer’s control panel. This can help correct issues related to image quality.
    • Go to Settings on the printer’s control panel.
    • Find Tools or Maintenance options and select Print Quality or Calibration.

4. Check Print Settings

  • Print Quality Settings: Ensure that the print quality settings are appropriately set. For best results, select a high-quality setting in the print dialog box.

5. Run a Test Print

  • Test Page: Print a test page or a diagnostic page from the printer’s control panel. This can help identify if the issue is with specific types of documents or graphics.

6. Check for Toner Smearing

  • Toner Smearing: If the lines are smudged or smeared, it could indicate a problem with the toner cartridge or the fuser unit.
    • Check the fuser unit for any toner build-up or damage.

7. Update or Reinstall Printer Drivers

  • Update Drivers: Visit the HP support website to download and install the latest drivers for your printer model.
  • Reinstall Drivers: Uninstall and reinstall the printer drivers to ensure there are no software-related issues causing the problem.

 

I hope this helps.

 

Take care and have a good day.
