The toner supply time unit "t" can be changed using SP31.
t = SP31 setting x 0.1 [second] (Default: 4 = 0.4 second)
S: TD Sensor Sensitivity (SP36)
* This value can be changed using SP35.
6.6.1 Toner Near End
If the CPU detects toner supply level 6 (V
T
≥ V
TS
+ 4S/5) five times
consecutively, the toner end indicator blinks and the machine goes to the
toner near end condition.
In this condition, the toner supply motor is energized for 10 seconds for every
copy (this time can be changed using SP35). Also, the toner supply motor
stays on continuously between pages of a multi-copy job.
If a toner sensor voltage lower than V
TS
+ 4S/5 is detected twice
consecutively while the toner supply motor is on, the machine recovers from
the toner near end condition. Also, if this condition is detected during the
normal copy cycle, the toner near end is canceled.
6.6.2 Toner End
If toner supply level 6 is detected, the machine supplies toner between
copies and for 10 seconds after the copy job is finished (as explained above).
While the toner supply motor is on, if the CPU detects toner supply level 7
(V
T
≥ V
TS
+S) three times consecutively, a toner end condition is detected
and copier operation is disabled.
If the toner sensor voltage stays at level 6 after the toner near end condition
is detected, 50 more copies can be made. After 50 copies, the toner end
indicator lights and copying is disabled.
