Toner Supply Motor On Time Determinations
For fixed control mode, the toner supply motor on time is specified by the setting of
SP2-925, and does not vary. The default setting is 200 ms for each copy. The
toner supply motor on time for each value of SP2-925 is as follows.
Value of SP2-925
Motor On Time (t = 200 ms)

Not supplied
For sensor control modes 1 and 2, the toner supply motor on time is decided by the
following factors.
•
Vt
•
Vref or Vts
•
TD sensor sensitivity (coefficient: S, value is 0.4)
There are seven levels for toner supply motor on time as shown below.
Level
Decision
Motor On Time (seconds)
1
(Vts or Vref) < Vt
≤
(Vts or Vref) + S/16
t (0.4)
2
(Vts or Vref) < Vt
≤
(Vts or Vref) + S/8
t x 2 (0.8)
3
(Vts or Vref) < Vt
≤
(Vts or Vref) + S/4
t x 4 (1.6)
4
(Vts or Vref) < Vt
≤
(Vts or Vref) + S/2
t x 8 (3.2)
5
(Vts or Vref) < Vt
≤
(Vts or Vref) + 4S/5
t x 16 (6.4)
6
Vt
≥
(Vts or Vref) + 4S/16 (near-end)
T (30); see note 3
7
Vt
≥
(Vts or Vref) + S (toner end)
T (30); see note 3
NOTE: 1) The value of “t” can be changed using SP2-922 (default: 0.4 second)
2) The value of “T” can be changed using SP2-923 (default: 30 seconds)
3) T (30) means that toner is supplied intermittently in a 1/3 duty cycle (1 s
on, 2 s off) for 30 seconds
