Getting a C6720( fuser ih belt rotation error) every time any of the right side doors are opened and then closed.
Swapped fuser with known good fuser, checked rotation sensor wire harness in fusers(per bulletin), updated firmware, replaced fuser drive motor assembly, checked connection of YC26 on engine pwb, checked for pinched wires, loose connections.
Once the error is reset, the machine will boot, and run hundreds of prints, until it jams, once a door is opened to remove jam, closes the door, the fuser faults. Or even while the machine is sitting at ready, if I open the main large door, or either of the 2 lower doors, once closed, faults.
Also if I press the energy saver button, the machine instantly throws a C6770 (fuser ih low electrical power)
My next steps will be to replace the fuser ih pwb, then the engine pwb.
Let me know
Thanks
