Error Codes CANON IR6800 We can't figure out what...

Question

Good morning, I hope you guys can help me, I have 2 companies and no one can find the problem. I have several Canon IR6800's 1 of them is showing an error code of E000008-0001 and the other is showing a code of E000013-0001 and they are both locked up with these codes. Does anyone know what these codes are and how to possibly fix them? I could really use the help.

Sincerely,

Ignacio E. Montero
