Toner and carbon clinging to the hot roller strippers can cause poor print quality. To prevent
this, toner and carbon are dislodged from the hot roller strippers by switching the fusing motor
on/off after every print job. These SPs set up the operation of this feature.

with SP3905 002 have been printed.
