Toner Supply Rate
925*
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.

Standard Vt
926*
Adjusts Vts (Vt for a new PCU). The TD sensor output
is adjusted to this value 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.

ID Sensor Control
927*
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 for a long time.

Toner End Clear
928*
Clears the toner end condition.

When making a lot of copies after changing this setting
to “1”, the carrier may be attracted to the drum when
the toner runs out, which may damage the drum.
