6.13 TONER SUPPLY AND RECYCLING

6.13.1 OVERVIEW
[B]
[A]
B070D902.WMF
Toner is supplied from a toner bank [A] on the left side of the machine and
separated from the development unit. The toner bank holds two bottles, but only
one bottle operates at a time.
A toner bottle motor turns the bottle [B], causing toner to leave the bottle and drop
into the toner entrance tank [C].
The toner transport coil in the toner transport tube [D] transports toner to the toner
supply cylinder [E]. Due to the length of the toner supply path, a toner supply pump
[F] is needed to draw the toner into the toner hopper [G].
Here are some important points to remember about the toner bank:
• The toner bank holds two toner bottles. This doubles the toner supply capacity
for the machine and allows replacement of an empty toner bottle while the
machine is operating.
• The machine works even if there is only one bottle installed.
• Toner can be supplied from either the upper or lower toner bottle, but not from
both at the same time. When toner runs out in one bottle, toner supply from the
other bottle starts automatically.
• After the toner near-end message is displayed for both toner bottles, the toner
bottle still has enough toner for about 200 copies.
• Load the lower toner bottle first, then the upper toner bottle. If the upper toner
bottle is loaded first, a message will be displayed on the operation panel to
request loading the lower toner bottle.
• Handle the toner bottles carefully to avoid shaking them.
