2.7 TONER SUPPLY AND RECYCLING
2.7.1 OVERVIEW
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.
