It's attached to the inside frame of the main drive unit.
Was there a fix for this. Have a customer who is getting this error quite a bit. My info is that we have replaced several items/sensor (on the transfer, I believe), and even replaced the transfer.
I do not think we have addressed the sensor mentioned above, did that fix the issue?

Humidity sensor # RDTCH0214FCPZ
Item # 3 Page 120 Parts book.
Try replacing and hopefully you should be good.
F2-78 is a known issue with a retrofitted upper drum seal and a mylar cover for the image density sensor. Check that this sensor is not covered in sh%t, located right under the transfer roller. Fuser cleaning on this model sucks and these frequently get gunked up.
Failing to plan is planning to fail!!!
