13-7. Sub Hopper Toner Replenishing Mechanism
• The Sub Hopper Toner Replenishing Motor replenishes toner from the Sub Hopper to the
Developer Mixing Chamber.
• The toner replenishing time is determined according to the T/C reading.
13-8. Sub Hopper Toner Empty Detection Control
• If T/C is not recovered to a level of 13 % or higher within a given period of time after the
copier has entered the T/C recovery mode, a toner-empty condition is detected.
✽ Given period of time: 35-cpm copier = 150 s; 25/20-cpm copier = approx. 209 s
• If T/C drops below 7 % as a result of making additional copies after the toner-empty con-
dition has been detected of the Sub Hopper, a defective ATDC Sensor results and the
copier displays the corresponding malfunction code.
✽ 20-cpm copier: U.S.A. and Canada Only
