M-color toner density target VL entry
To enter the target value of the ATR Sensor (M) of ATR control after replacement of the DC
Controller PCB/clearing of RAM data.
When checking the value before replacement of the DC Controller PCB/clearing of RAM data and
then re-entering the value after clearing of the data
Enter the setting value, and then press OK key.
0 to 255
120 (It may vary by initialization of the Developing Unit when clearing RAM data.)

C-color toner density target VL entry
To enter the target value of the ATR Sensor (C) of ATR control after replacement of the DC
Controller PCB/clearing of RAM data.
When checking the value before replacement of the DC Controller PCB/clearing of RAM data and
then re-entering the value after clearing of the data
Enter the setting value, and then press OK key.
0 to 255
120 (It may vary by initialization of the Developing Unit when clearing RAM data.)
COPIER> FUNCTION> INSTALL> INISET-C/4
ATR patch Bk-clr toner dens tgt VL entry
To enter the Bk-color toner density target value of ATR patch to be formed on the ITB.
The Bk-color toner density is detected by the Registration Patch Sensor Unit (Front).
The value is determined whenever the Developing Unit (Bk) is initialized.
When checking the value before replacement of the DC Controller PCB/clearing of RAM data and
then re-entering the value after the processing is done
Enter the setting value, and then press OK key.
When INISET-K is executed, the value is rewritten.
0 to 1023
350 (It may vary by initialization of the Developing Unit when clearing RAM data.)
COPIER> FUNCTION> INSTALL> INISET-K
Adj Y-clr toner dens tgt VL upper limit
To adjust the upper limit of the toner density target value of the Toner Density Sensor (Y).
As the value is incremented by 1, the upper limit is increased by 0.5%.
Increase the value when a density failure/coarseness occurs, and decrease the value when
fogging/scattering occurs.
In principle, the value should be the same as that of LLMT-PTY.
When an image failure (density failure, coarseness, fogging, carrier adherence, scattering, etc.)
occurs
Enter the setting value (switch negative/positive by -/+ key) and press OK key.
Take necessary action in accordance with the instructions from the Quality Support Division.
