Printing solid line on left side of page

Hi @R10001,

Welcome to HP Support Community.

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

A solid line on the left side of the page can be caused by several factors. Here are some troubleshooting steps you can try.

• Clean the printhead: Use the printer's utility software to clean the printhead. This can help remove any dried ink or debris that might be causing the issue.
• Check for obstructions: Open the printer and check for any obstructions along the paper path, especially near the left side where the line is appearing. Even small pieces of paper or debris can cause printing issues.
• Check the ink cartridges: Make sure the ink cartridges are properly installed and have enough ink. Sometimes, low ink levels or improperly installed cartridges can cause printing problems.
• Adjust paper settings: Make sure the paper size and type settings in the printer driver match the paper you're using. Using the wrong settings can sometimes cause printing issues.
• Update printer drivers: Ensure that you have the latest drivers installed for your printer. Sometimes, outdated drivers can cause printing problems.
• Inspect the paper tray: Check the paper tray for any damage or misalignment. If the paper isn't feeding properly, it could cause printing issues like this.
• Run a printer diagnostic: Many printers have built-in diagnostic tests that can help identify and resolve printing problems. Check your printer's user manual for instructions on how to run a diagnostic test.

By going through these steps, you should be able to identify and resolve the issue causing the solid line on the left side of the page.

I hope this helps.

Take care and have a good day.
