1 Vtcnt
Gain value calculated during TD sensor initialization. This is used
to adjust the Vt (TD sensor output). A large gain increases Vt, and
a small gain decreases it. The result of this calculation is also
used to calibrate Vt during TD sensor initialization.
2 Vt(H)
3 Vt(M)
4 Vt(L)
"x" is K, M, C, or Y.
The Vt readings are H (High), M (Medium), L (Low).
3021 Set Vt Shift
Use this SP to correct Vt (TD sensor output voltage) in the low speed mode
(128 to 256 g/m
2
). The machine then uses this value to calculate Vt for low
speed mode.
1 Shift (Stdd1)
2 Shift (Half d2)
3 Shift (Half d1)
V-C2a [0 to 5/ 0/ 0.01 V]
V-C2b [0 to 5/ 0.2/0.01 V]
3042 Set Vtref Cor
Set Vtref Correction.
Vtref is frequently updated in the toner supply cycle to stabiize the
concentration of toner in the developer. Vtref is corrected between every printed
page in the paper path using the correction amounts listed below for each color.
This is the default setting (0) for SP3042 001. However, you can use this SP to
switch this function off.
Vtref (TD sensor reference voltage). It is frequently updated to stabilize the
toner concentration in the development unit.
1 Vtref Corr Mode
[0 to 1/1] 0: On, 1: Off
Setting this SP to 1 switches off Vtref correction
between pages.
