When printing envelopes on my HP LaserJet Pro MFP M127fw printer I'm getting a double printing of the address.  Both imprints are smudgey and unusable

Hi @gtcoder,

Welcome to The HP Support Community.  

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

I understand you're experiencing a printing issue with your HP LaserJet Pro MFP M127fw when printing envelopes. Here are some steps you can take to troubleshoot and hopefully resolve the issue:

• Check Envelope Loading: Ensure that you're loading the envelopes correctly into the printer's paper tray. Improper loading can cause smudging and double printing.
• Paper Type Setting: Make sure that the paper type setting in your printer's driver matches the type of envelope you're using. You can usually adjust this setting in the printer properties or settings menu on your computer.
• Printer Settings: Check the printer settings to ensure they're configured correctly for envelope printing. There might be specific settings related to envelope printing that need to be adjusted, such as paper size and paper type.
• Print Quality Settings: Adjust the print quality settings in the printer driver. Lowering the print quality may help reduce smudging and improve the overall print quality.
• Clean Printer: If the printer's print heads or rollers are dirty, it can cause smudging and double printing. Follow the manufacturer's instructions for cleaning the printer, including cleaning the print heads and rollers.
• Update Printer Driver: Make sure you have the latest printer driver installed on your computer. Sometimes, outdated drivers can cause printing issues. You can download the latest driver from the HP website. Software and Drivers for HP LaserJet Pro MFP M127fw

• Check Printer Supplies: Ensure that the toner cartridge and other printer supplies are in good condition. A low or faulty toner cartridge can cause printing problems.
• Test with Different Envelopes: If possible, try printing on different types or brands of envelopes to see if the issue persists. It's possible that the problem is specific to the type of envelope you're using.

Thank you for taking the time to reply.  I appreciate the feedback and advice, but this was very generic feedback.  I've been using the same envelopes for years and have printed dozens and dozens of envelopes successfully.  Interestingly, I have no issues with printing on letterhead using the same stock of paper, from the same supplier (VistaPrint).   No issues with printing documents on letterhead stock or otherwise, no issues printing on check stock.  Perhaps you are right with the cleaning advice.  I would welcome any advice or tutorial on how to clean the deep internals which is where I suspect the problem is.
