 I ask for help

Good day. Help people, please. Whoever understands this, I don’t have close, searches didn’t give anything .. The question is about the HP Officejet Pro 6830. 

At the beginning, it turned green (I had to print a photo) after an intensive hour-long struggle with this, I decided to reset it and return it to factory settings. 

After which he began to blink blue on the screen and writes C4EBA341.

 I checked it everywhere, nothing extra stuck in it. 

In general, I do not know what else to do. 

A photo is needed until tomorrow. 

Can someone help me? 

Well, in addition to advice, contact the service center and restart the printer.
