white lines through print

[bmike1]

I have an envy 7855 with blank lines through the print. There was a solution but the link it references is dead. How do I fix this? I asked this before but lost the email with the instructions when I wanted to perform the clean (or whatever I had to do).

Hi @bmike1,

Welcome to The HP Support Community.  

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

I understand you're experiencing print quality issues with your HP ENVY Photo 7855 printer, specifically blank lines appearing on your prints. This problem could be caused by a variety of factors, such as clogged printheads, low ink levels, or issues with the printer settings.

Here are some steps you can take to troubleshoot and potentially fix the issue:

• Check Ink Levels: Ensure that your ink cartridges have sufficient ink levels. If any of the cartridges are low, consider replacing them.
• Clean Printheads: You can try cleaning the printheads to remove any clogs or debris that may be causing the blank lines. Most printers have a built-in printhead cleaning function accessible through the printer settings. You can typically find this option in the printer's control panel or through the printer software on your computer.
• Print Quality Diagnostic: Many printers have a print quality diagnostic tool that can help identify and fix common printing issues. Look for this option in your printer's settings or control panel.
• Alignment: Check if your printer has an alignment function and perform an alignment if necessary. Misaligned printheads can also cause blank lines or poor print quality.
• Update Printer Drivers: Make sure that your printer drivers are up to date. Sometimes, outdated drivers can cause printing issues. You can usually download the latest drivers from the HP website. Software and Drivers for HP ENVY Photo 7855 All-in-One Printer
• Manual Cleaning: If the above steps don't resolve the issue, you may need to manually clean the printheads. Refer to your printer's user manual for instructions on how to do this safely.
