@Bisque, Welcome to the HP Support Community! I’m here to help.

I understand you are not able to use the printer due to this error. 

Make sure the ink cartridges are properly inserted in the printer, you may refer to - Replace HP inkjet printer cartridges

Use HP ink cartridges.

Kindly perform the steps mentioned in this document - Ink cartridge error

Kindly perform the steps mentioned in this document - Carriage jam or E3 error

Also, make sure there are no paper jams inside the printer - Paper Jam Error

If the issue persists, I'm afraid this is a hardware failure. Please reach out to the HP Technical Support team in your region regarding the service/replacement options for your printer. 

You may create a case on the website to obtain a case number if required. Kindly watch this video to know how.

Keep me posted for any other assistance.

I have an issue with my HP EliteBook G40 G3, it automatically boots into system diagnostics anytime i switch it on. I tried bios default settings load, didn't work, I tried running new windows didn't resolve and then i did system restore from the Bios settings, I installed new HP diagnostics software but all to no avail.

What do I do?
