@MissyM75, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It sounds like the flashing lights and error messages you are experiencing on your HP DeskJet 4155e might be related to an issue with the printer settings or paper alignment. Here are steps you can take to troubleshoot and resolve the issue:

Step-by-Step Troubleshooting:

Check Paper Alignment:

• Ensure that the paper you are using is placed correctly in the paper tray with the guides snug against the paper. Misaligned paper can often trigger error messages.

Inspect the Paper Path:

• Check for any obstructions or paper jam remnants in the printer. Envelopes can sometimes leave stray particles in the printer path.

Reset the Printer:

• Unplug the printer from the power source again. Wait about 60 seconds before plugging it back in to ensure a full reset. Turn on the printer after reconnecting.

Printhead Alignment:

• Perform a printhead alignment via the printer's control panel or HP Smart app. This can often resolve alignment issues that arise after switching paper types.

Update Printer Software:

• Make sure that your printer software is up to date. You can check for updates through the HP Smart app.

Check for Hardware Issues:

• Occasionally, hardware issues such as stuck buttons can cause random errors and lights. Ensure all buttons can be pressed without sticking and the power cord is securely connected.

Also, I suggest you refer to this guide: HP DeskJet 2700, 4100, 4800 printers - Blinking lights and error codes | HP® Support
