SP2 Mode Number Function and [Setting]
2208* 01 Toner Supply Mode Selects the toner mode.
0 : Sensor control
1: Image pixel count.
If you select 1, set SP2209-02 to its default
value. Use image pixel count mode only as a
temporary measure if the ID or TD sensor is
defective and a replacement is not available.
Toner Supply Rate Adjusts the toner supply rate.
01 Toner Rate Sets the amount of toner supplied every second
by the toner supply motor.
Increasing this value reduces the toner supply
clutch on time. Use a lower value if the user
tends to make lots of prints that have a high
proportion of black.
[10 ~ 800 mg/s / 60 mg/s / 5 mg steps]
2209*
02 Toner Rate
(Supply Correction Data) Displays the toner supply correction coefficient
(K). It can also be used to adjust K, but the value
is changed again when V
T
(V
TD
, the output of
the TD sensor) is measured for the next print.
The toner supply rate depends on the amount of
toner in the toner bottle. This change is
corrected using this coefficient. This SP can be
used to check the toner supply condition. The
lower the value of K, the lower the toner density.
[0.25 ~ 3.0 / 3.0 / 0.25 steps]
2210* 01 Pattern Interval (ID Sensor) Sets the interval between ID sensor pattern
prints for toner control. This setting allows
adjustment for customers who do not make
many prints daily. Selecting zero cancels
creation of the ID sensor pattern.
[0 ~ 200 /
10 / 1 print step]
The ID sensor reads the sensor pattern and
outputs this reading as Vsp and sends it to the
CPU where it is used to calculate Vref (Vsp/Vsg
= Vref).
If the total count exceeds 10 during a print job,
for example “15”, the pattern is created and read
at completion of the print job.
