Hi @RobBob1968,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
It sounds like your HP ENVY 6452e printer is displaying an E6 error with all lights flashing. This typically indicates a hardware issue that may require further troubleshooting or service. Here are a few additional steps you can try.
Check for Jammed Paper: Ensure there are no small pieces of paper stuck inside the printer that may not be immediately visible. Even a small scrap of paper can cause the printer to display an error.
Inspect Cartridges: Remove and reseat both the black and color ink cartridges. Make sure they are properly installed and securely seated in their respective slots.
Power Cycle the Printer: Disconnect the power cord from the printer and from the power outlet. Wait for about 3-5 minutes to allow any residual power to dissipate. Then reconnect the power cord directly to a wall outlet (avoid using a surge protector or power strip) and turn the printer back on.
Reset the Printer: Sometimes, performing a semi-full reset can help. To do this:
- Turn on the printer, if it is not already on.
- With the printer powered on, disconnect the power cord from the rear of the printer.
- Wait for about 30 seconds.
- Plug the power cord back into the printer.
Update Firmware: Ensure your printer's firmware is up to date. Visit the HP website, enter your printer model details, and download any available firmware updates.
I hope this helps.
Take care and have a good day.
