Hi @Theodoor61,

Welcome to HP Support Community.

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

A blue screen with changing error codes on your HP Envy 7645 printer typically indicates a hardware or firmware issue. Here are some steps you can take to troubleshoot.

• Power Cycle: Turn off the printer, unplug it from the power source, wait for about 60 seconds, then plug it back in and turn it on.
• Check Connections: Ensure all cables are securely connected. If you’re using a network connection, check the network cables and ensure they are properly connected.
• Firmware Update: Check if there's a firmware update available for your printer. You can do this through the HP support website or using the HP Smart app if it’s compatible with your model.
• Reset Printer: Perform a factory reset on your printer. This is usually done through the printer’s control panel or settings menu. Check your printer’s manual for specific instructions on how to perform a reset.
• Check for Hardware Issues: Inspect the printer for any obvious hardware issues, such as paper jams, foreign objects, or misaligned components. Remove any obstructions if found.

I hope this helps.

Take care and have a good day.
