Probably a missing 24v issue Drum ITB Motor (M1) --check for 24v
++++ Check and/or replace the Double Switch PCB Assembly (FG6-9015-000) located in the rear of the copier behind the DC controller.
24V I/L supply (to the ITB Motor (M1)) passes through Fuser Carriage switches MSW 5/6, Front Cover Open/ Closed detection switches MSW 1/2, and Manual Feed unit Open/ Closed detection switches MSW 3/4.
If the voltage is not present at the motor, trace it back to the fuse pcb.
As the machine starts initial rotation, an E012-0001 error occurs.
24 V DC is measured at J71 pin 1 and 0 V DC is measured on pin 3 (normally 24 V DC is measured on both pins). The 24 Volts on pin 1 is fed through all 6 interlock switches and back to pin 3. If you're missing the the voltage on pin 3, check the interlocks for an "open".
Workaround :
In this case there was an open in the front door interlocks.
Below is a diagram of the printer with the interlocks highlighted in red.

That wonderful fuse pcb.....make sure none of your drums or itb assembly are seized
Had power at j71 connector pin 1and 3,,but lost it my fault,,what fuse should i check to regain power...thanks,,
