Sharp MX-M264n error code L4-01

Hi all

Looking for a little help. First sharp I'm working on. So If my question sound a little stupid ,please forgive me.
Have a MX-M264n throwing a L4-01 code. Goes through the start up than codes out.Sounds like the drive motors are not coming on. The DV, drum and fuser are not binding.
I tried resetting the code using P*C*. No change.

What would/is the most likely cause of this code and how to confirm this.

Thanks for the help.
