@Jim0507, Welcome to HP Support Community. 

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

The issue of lines appearing on the side of printed documents, especially after the computer warms up, could be caused by a few different factors:

Possible Causes & Solutions

Dirty or Clogged Printheads

• The printhead may be clogged, causing streaks or lines in prints.
• Solution:
  • Open HP Smart or HP Printer Assistant and run the Printhead Cleaning tool.
  • Print a Print Quality Diagnostic Page to check for inconsistencies.

Low or Defective Ink Cartridges

• If the ink levels are low or the cartridge is defective, it can result in printing defects.
• Solution:
  • Check ink levels from the printer’s control panel or HP Smart app.
  • Replace any low or faulty ink cartridges.
  • Ensure you are using genuine HP ink.

Paper Issues

• Low-quality or damp paper can cause smudging or lines.
• Solution:
  • Use high-quality, dry paper recommended for your printer.
  • Store paper in a cool, dry place.

Printer Alignment Issues

• If the printer is misaligned, it can cause streaks or lines.
• Solution:
  • Run the Align Printhead tool from the printer menu.
  • If available, manually realign using HP Smart.

Internal Hardware Issue (Overheating)

• If this happens only after the computer/printer warms up, there might be an issue with the printer hardware.
• Solution:
  • Let the printer cool down and then try printing again.
  • Try plugging it into a different power outlet.
  • Perform a hard reset:
    1. Turn off the printer.
    2. Unplug it from power for 60 seconds.
    3. Plug it back in and restart.

Firmware/Driver Issues

• If the printer firmware or drivers are outdated, printing errors may occur.
• Solution:
  • Visit HP Support and download the latest firmware/drivers for your printer.
  • Uninstall and reinstall the printer software.

I hope this helps. 

Take care and have a good day.
