Hi @Lynnhodges,

Welcome to HP Support Community.

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

The issue you’re describing with your HP PageWide Pro MFP 477dw sounds like it might be due to a problem with the printhead or the printhead nozzles being clogged. Here are some steps you can take to try and resolve this issue.

Check Printhead Health

1. Print a Print Quality Report:
   • On the printer’s control panel, go to Settings.
   • Select Reports.
   • Select Print Quality Report.
   • This report can help identify any issues with the printhead.

Clean the Printhead

1. From the Printer Control Panel:
   • On the printer’s control panel, go to Settings.
   • Select Tools.
   • Select Clean Printhead.
   • Follow the on-screen instructions. You may need to run the cleaning cycle several times.

Align the Printhead

1. From the Printer Control Panel:
   • On the printer’s control panel, go to Settings.
   • Select Tools.
   • Select Align Printhead.
   • Follow the on-screen instructions.

Check the Ink Cartridges

1. Inspect the Ink Cartridges:
   • Open the ink cartridge access door.
   • Make sure the cartridges are properly installed.
   • Check for any ink leaks or damage to the cartridges.

Firmware Update

1. Update Printer Firmware:
   • Go to the HP support website and check for any firmware updates for your printer model.
   • Download and install any available updates.

Manual Printhead Cleaning

1. Clean the Printhead Manually:
   • Turn off the printer and unplug it from the power source.
   • Open the ink cartridge access door and remove the ink cartridges.
   • Locate the printhead and gently clean it with a lint-free cloth dampened with distilled water.
   • Allow the printhead to dry completely before reinstalling the cartridges and powering the printer back on.

I hope this helps.
