That's "Drum Up/Down Color: Magenta" "When the magenta drum has been detected in an abnormal position."
The book says to replace the magenta drum unit (did that). Also replaced magenta toner cartridge. Then I swapped the magenta drum motor and gear with the identical yellow drum motor & gear. By the way that was quite a treat getting to the drum motors. The error did not change to the Fatal Error 140 ("Drum......Yellow"), so I've ruled out the drum motor, gear, drum unit, toner cartridge, & guide rails left & right.
The M drum motor does rotate in reverse during initialization (along with all the other drum motors). The magenta transfer roller lifts when the M-drum motor is in reverse.
I also swapped the cyan drum/toner unit with the magenta drum/toner unit. The error stay 141 for magenta.
I'm running out of ideas here. What am I missing? =^..^=
