@Niezaja, 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

When all lights are blinking on your HP Smart Tank 750 printer, it could indicate several potential issues, such as a paper jam, printhead problem, or another error condition. Here's a guide to help you resolve the problem:

Check for Paper Jams

• Open the printer and inspect the input and output trays for any jammed paper. Carefully remove any paper you find.

Inspect Printhead and Carriage

• Lift the ink access door and ensure the printhead carriage is not obstructed. Make sure the printhead cover is securely closed.

Check Ink Levels

• Verify that the ink tanks have sufficient ink. If any tanks are low or empty, refill them accordingly.

Reset the Printer

• With the printer turned on, disconnect the power cord from the printer.
• Unplug the power cord from the power source and wait for 60 seconds.
• Reconnect the power cord directly to a wall outlet and the printer. Turn on the printer.

Refer to Error Codes

• Look at the printer display or control panel to identify any specific error codes that might indicate the problem.

Also, i suggest you refer to this guide: HP Smart Tank 670, 720, 750, 790 Printers - Blinking lights and error codes | HP® Support
