Ricoh B234 Service Manual page 859

Here are some important points to remember about the toner bank:
• The toner bank contains the toner bottles, the toner collection bottle below the
bottles. The toner entrance tank comprises the back side of 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.
• The lower toner bottle is loaded first, then the upper toner bottle is loaded. If the
upper toner bottle is loaded first, a message will be displayed on the operation
panel to request loading the lower toner bottle.
• Toner bottles should always be handled carefully to avoid shaking them.
