1. DETAILED SECTION DESCRIPTIONS

1.1 TONER AND DEVELOPER

The toner and developer have been changed over to a finer-grained type.

Developer
These changes were made to maximize the reproduction in halftone areas and the
evenness of the image density in black solid areas.
1.2 NEWLY ADDED: DEVELOPMENT SUCTION MOTOR AND
SUCKED TONER COLLECTION BOTTLE
In order to ensure that the new granular
toner does not scatter, a development
suction motor [A] has been added to
decrease the pressure inside the
development unit [B]. This motor is on
whenever the development motor is on.
When air is sucked out of the development
unit by the motor, there is also some toner
included (although very minimal). A sucked
toner collection bottle [C] has been added to
collect this toner.
The new bottle and motor have Near
End/End and replacement time conditions,
respectively. The display for the existing
waste toner bottle Near End/End is used.
As the alerts can only be displayed for one
component at a time, when displayed, use
SP2971 to confirm which component it is
referring to.
The target replacement intervals are as follows:

NOTE: The End condition alert is a pop-up window, and the Near End alert is a 1-
line display.
