Points to Note When Removing Drum Unit
When removing the drum unit, make sure that the shutter lever is at the
'Unlock' position.
If removing the drum unit from the host machine while the shutter lever is
not at the 'Unlock' position, and then mounting the unit again after shifting
the lever to the 'Unlock' position, the shutter of the drum unit is not opened
properly.
Therefore, toner does not get into the drum unit from the hopper assembly,
and the spilled toner strays within the host machine. If removing the drum
unit from the host machine while the shutter lever is not at the 'Unlock'
position, put the unit back and shift the shutter lever to the 'Unlock' position,
and then, remove the unit.
15) Release the tip-resistant arm [1]. Push the left and right seal areas [2] of
the ITB cover simultaneously to close surely the ITB unit.
