My documents are getting mangled during the printing process.

My documents are getting mangled during the printing process. This is the second printer in two months that just aged out of warranty. Does anyone have a simple solution for this or do I need to replace both printers?

Hi @Reba_HH,

Welcome to The HP Support Community.  

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

I understand you're dealing with this issue! Here are a few troubleshooting steps to help you resolve the problem with your HP OfficeJet Pro 7740:

• Check for Paper Jams: Sometimes, paper jams or obstructions can cause mangled prints. Open all the paper trays and access areas to make sure there's no paper stuck inside.
• Inspect the Paper Path: Look for any worn or dirty rollers in the paper path. Clean them gently with a lint-free cloth and distilled water if they're dirty. Make sure the rollers are not damaged.
• Use the Correct Paper Type: Ensure you're using the recommended paper type and size for your printer. Sometimes, using paper that is too thick or too thin can cause issues.
• Update Printer Firmware: Make sure your printer’s firmware is up-to-date. Check the HP website or use the HP Smart app to find and install any available updates. Update the firmware on an HP printer
• Check Printer Settings: Verify that your printer settings match the paper type and size you’re using. Incorrect settings can sometimes lead to mangled documents.
• Run Printer Diagnostics: Use the built-in diagnostic tools available in the printer’s settings menu or the HP Smart app. These tools can help identify and troubleshoot issues.
• Clean the Printheads: If your prints are coming out mangled, the printheads might be clogged or dirty. Run the printhead cleaning cycle from the printer’s menu.
