Function
Adjusts the toner supply motor on time for
sensor supply mode.
This SP is effective only when SP2-921 is
"0" or "1".
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.
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".
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.
Adjusts the toner supply rate for fixed toner
supply mode.
This SP is effective only when SP2-921 is
"2" or "3".
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. See "Toner
Density Control" for more details.

during the TD sensor initial setting process.
This SP is effective only when SP2-921 is
"0", "1", or "2".
Do not change this value.
Selects whether the ID sensor is used or not
for toner density control.
If this value is "0", dirty background may
occur after the machine has not been used
