[Cause]
Pulling the jammed paper towards to the upstream when clearing ADF jam, the paper may get stuck to the roller holder sheet [1]
or the paper feed sheet [2] causing these sheets to flip inward and remain in that state. When feeding paper from ADF in this
state, the paper gets stuck to the flipped sheets which are blocking the paper path. This causes the above symptom to occur.
The photo below [1] shows the roller holder sheet in a normal state and the photo [a] shows the sheet flipped inward [a]. The
photo below [2] shows the paper feed sheet in a normal state and the photo [b] shows the sheet flipped inward.
