No print possible, warning light is blinking (!), HP LaserJet MFP M140w

[crutchmount80]

The exclamation mark on the printer 
is blinking rapidly. Error report can 
be printed, indicates that you can get 
more information in the HP app. Run Error 
Doctor. This says that there is an error 
and you can only print again once it has 
been corrected. It doesn't say what the 
error is or how to fix it. Ink cartridge 
is still almost full, device is only a few 
weeks old, latest drivers are installed. 
Unplug the power cord, tried everything. 
Had stopped printing after 20 out of 25 
pages. Since then only this error message.

Welcome to the HP support community.

I understand that you are getting attention light on the printer is blinking, I am glad to assist you.

If there is no error message on the application, follow these steps to fix the issue:-

Perform a power reset , Reset the printer to recover from printer errors or failures.

1. Turn on the printer, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Wait at least 30 seconds.
5. Plug back the power cable straight to a wall outlet and printer without any surge protector.
6. Turn on the printer.
