HP Laserjet 4158e 'EE' error code

Hi,

I can't print due to an error code EE appeared and three flashing lights. I have tried all of the recommendations such as turning off, unplugging, restarting, checking cartridges, removing paper etc. and nothing has worked. 

Please provide some help as I have run out of ideas and there are no recommendations for what to do with an Error Code EE problem.

Thanks
