Notes:
1. Be extremely careful when handling this
unit because toner may spill out from the
joint with the toner recycle unit, cleaner
unit and developer unit.
2. Install the window of the shutter section
on the toner recycle unit so that it
matches with the protrusion of the devel-
oper unit.
3. Be careful to allow as little vibration as
possible to the unit when installing and
removing the toner recycle unit. Vibration
could cause stains on the image after
assembling, especially when the remain-
ing toner amount in the cartridge is small.
