Hi @TCH70,

Welcome to The HP Support Community.  

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

I understand you are getting the E6 error on your HP ENVY 6430e All-in-One Printer indicates a general printer error, often associated with issues related to the printer's internal mechanisms or hardware. 

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

• Power Cycle the Printer: Turn off the printer, unplug it from the wall outlet, and wait for about 60 seconds. Plug it back in and turn it on.
• Check for Paper Jams: Make sure there are no paper jams in the printer. Open all access panels and remove any stuck paper. Look for bits of paper that might not be immediately visible.
• Inspect Cartridges: Since you have already changed the cartridges, double-check to ensure they are installed correctly. Remove and reinsert them to ensure a proper connection. Make sure the protective tape has been removed from the new cartridges.
• Update Printer Firmware: Sometimes, firmware issues can cause errors. Check if there’s a firmware update available for your printer through the HP Smart app or on the HP website. Update the firmware on an HP printer
• Reset the Printer to Factory Settings: If the issue persists, you might want to consider resetting the printer to its factory settings. This can sometimes clear error states.
