Toner Empty Detection
The copier has no toner empty detecting sensor and, instead, the ATDC Sensor performs
that function. The ATDC Sensor checks the toner-to-carrier ratio and, if it reads a T/C ratio
lower than the reference level for 37 copies and, further, if it next reads a ratio 1% lower
than the reference level, this is a toner-empty condition. The toner-empty condition is can-
celed after detection under any of the following conditions when the Front Door is swung
open and closed:
• T/C is 4% or more: The toner-empty condition is canceled.
• T/C is less than 4%: The copier initiates an Auxiliary Toner Replenishing sequence and
cancels the toner-empty condition as soon as T/C reaches 4.5%.
In addition, if the Tech. Rep. Choice setting has been made to inhibit the initiation of a new
copy cycle in a toner-empty condition, the copier permits the initiation of a new copy cycle
as soon as T/C reaches 4.0%.
