SYMPTOM
SC486 will occur even after a new waste toner bottle is set.
CAUSE
The tips of couplings [A] and [B] contact each other when the waste toner bottle is installed, which
prevents them from engaging properly. As a result, coupling [B] is pushed into the machine in the
“disengaged position” (see below), preventing the waste toner transport coil from rotating.
