Adjusts the toner supply motor on time for
sensor supply mode.
This SP is effective only when SP2-921 is
“0” or “1”.
2-922*
Toner Supply Time
Increasing this value increases the toner
supply motor on time. So, use a high value if
the user tends to make lots of copies that
have a high proportion of black.
0.1 ~ 5.0

0.6 s
Adjusts the toner supply motor on time
during recovery from toner near-end/end.
This SP is effective only when SP2-921 is
“0”, “1”, or “2”.
2-923*
Toner Recovery
Time
Note that toner recovery is done in a 3-
second cycle. So, the input value should be
a multiple of 3 (e.g. 3, 6 ,9). See “Toner
Density Control” for more details,Section
2.6.6.
