I suspect you have a missing 36V supply for the stepper motors.

Check fuse F34 is not blown on the printer I/O PCB (J390615)

Make sure LED all the green LED's are lit on the printer I/O PCB.

Dear Profs,

I'm not trying to steal the original problem reported in this post, but trust that anybody can still benefits from all your advice.

I currently have similar problem with my 2611.

error message is :6021-01 reverse unit right vertical operation error.

I notice that the right hand lift motor is not working and feels hot when last checked.

my technician is stuck as he could not solve this since 4 days now. he swapped the motor to the left side and it worked, so the motor is good. not sure it could be the PCB.

what could be my problem?

note please; before this last problem, each the printer is switched on, there will be error code 6017-10, and that paper has jammed in reverse unit. I will normally open the doors and close them, clear the message and resume work.

many thanks for your help.
