Hi @ampow,

Welcome to HP Support Community.

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

Horizontal striping issues in printing can be caused by several factors, including clogged printheads, low ink levels, or mechanical problems. Here's a step-by-step guide to troubleshoot and potentially resolve the issue with your HP Envy 4520 printer.

• Check Ink Levels: Ensure that your ink cartridges have sufficient ink levels. Low ink levels can cause printing problems, including horizontal stripes. Replace any empty or low ink cartridges with new ones if necessary.
• Run Printer Diagnostic Test: Most printers, including the HP Envy 4520, have a diagnostic test or cleaning function built into their software. You can usually access this through the printer's control panel or the accompanying software on your computer. Run a diagnostic test to check for any issues with the printheads or ink nozzles.
• Clean Printheads: If the diagnostic test reveals issues with the printheads, you can usually clean them using the printer's utility software. This option is often found in the printer settings or maintenance menu. Follow the on-screen instructions to initiate the printhead cleaning process.
• Manual Printhead Cleaning: If the automatic cleaning process doesn't resolve the issue, you can manually clean the printheads. Refer to your printer's user manual for instructions on how to remove and clean the printheads safely. Be cautious when handling printheads to avoid damaging them.
• Check for Paper Jams: Horizontal striping can sometimes be caused by obstructions in the paper path, such as paper jams or debris. Check the printer thoroughly for any paper jams or foreign objects, and remove them carefully.
• Update Printer Drivers: Ensure that your printer drivers are up-to-date. Sometimes, outdated or corrupted drivers can cause printing issues. Visit the HP website to download and install the latest drivers for your HP Envy 4520 printer.
• Try Different Paper: In some cases, the type or quality of paper being used can affect print quality. Try printing on a different type or brand of paper to see if the issue persists.
• Reset Printer: If none of the above steps resolve the issue, try resetting your printer to its factory defaults. This can sometimes clear out any software glitches or settings that may be causing the problem. Refer to your printer's user manual for instructions on how to perform a factory reset.

I hope this helps.

Take care and have a good day.
