Two error messages 79:04 & 86:01

Microsoft Windows 10 (64-bit)

I am trying to re-align print heads and get an error message part way through the process - 79:04

I have to turn off and then turn on the printer to be able to use the printer. Still not able to re-align print heads after the restart.


Any ideas?

You have to do the following.
1. Check the garanty expired date of head. If the all head are out of date. You most changes.
2. Check the carriage belt
3. You must to do maintenance.
Now, If you do not solve this, you should probably change the head carriage.

I hope help.
Best regard
