Sub item
SIGG-Y Display the gain value for the Y-color toner density standard signal for ATR control.
Display the Y-color patch level when executing ATR-INIT, which is executed at PCRG initialization.
Use this item to determine a cause of a density fault.
When replacing the DCON PCB, enter the unique ATR-INIT value for each PCRG.
Setting range: 0 to 255
[Factory setting value/Value after RAM clear: 0]
SIGG-M Display the gain value for the M-color toner density standard signal for ATR control.
Display the M-color patch level when executing ATR-INIT, which is executed at PCRG initialization.
Use this item to determine a cause of a density fault.
When replacing the DCON PCB, enter the unique ATR-INIT value for each PCRG.
Setting range: 0 to 255
[Factory setting value/Value after RAM clear: 0]
SIGG-C Display the gain value for the C-color toner density standard signal for ATR control.
Display the C-color patch level when executing ATR-INIT, which is executed at PCRG initialization.
Use this item to determine a cause of a density fault.
When replacing the DCON PCB, enter the unique ATR-INIT value for each PCRG.
Setting range: 0 to 255
[Factory setting value/Value after RAM clear: 0]
SIGG-K Display the gain value for the K-color toner density standard signal for ATR control.
Display the K-color patch level when executing ATR-INIT, which is executed at PCRG initialization.
Use this item to determine a cause of a density fault.
When replacing the DCON PCB, enter the unique ATR-INIT value for each PCRG.
Setting range: 0 to 255
[Factory setting value/Value after RAM clear: 0]
T-SPLY-Y Adjust the toner supply amount (Y-color)
Adjustment method:
When executing RAM clear for the DC controller PCB or replacing the DC controller PCB, enter the value indicated on
the service label.
Adjustment range: -3 to 3
[Factory setting value/Value after RAM clear: 0]
T-SPLY-M Adjust the toner supply amount (M-color)
Adjustment method:
When executing RAM clear for the DC controller PCB or replacing the DC controller PCB, enter the value indicated on
the service label.
Adjustment range: -3 to 3
[Factory setting value/Value after RAM clear: 0]
T-SPLY-C Adjust the toner supply amount (C-color)
Adjustment method:
When executing RAM clear for the DC controller PCB or replacing the DC controller PCB, enter the value indicated on
the service label.
Adjustment range: -3 to 3
[Factory setting value/Value after RAM clear: 0]
T-SPLY-K Adjust the toner supply amount (K-color)
Adjustment method:
When executing RAM clear for the DC controller PCB or replacing the DC controller PCB, enter the value indicated on
the service label.
Adjustment range: -3 to 3
[Factory setting value/Value after RAM clear: 0]
DMAX-K Adjust the offset for the target value of K-color density control.
Adjustment method:
Set the offset value for the target value of K-color density control at D-MAX control.
Setting range: -8 to 8
[Factory setting value/Value after RAM clear: 0]
P-TG-Y Adjust the offset for the target value (Y-color) of ATR control.
Add the offset to the ATR patch TGT which was determined at initialization, and change the T/D ratio.
Changing the setting value by 1 will add the offset value by 30 levels to ATR patch TGT.
Use this item for low/high density or fogging images.
Setting range: -4 to 4
[Factory setting value/Value after RAM clear: 0]
P-TG-M Adjust the offset for the target value (M-color) of ATR control.
Add the offset to the ATR patch TGT which was determined at initialization, and change the T/D ratio.
Changing the setting value by 1 will add the offset value by 30 levels to ATR patch TGT.
Use this item for low/high density or fogging images.
Setting range: -4 to 4
[Factory setting value/Value after RAM clear: 0]
P-TG-C Adjust the offset for the target value (C-color) of ATR control.
Add the offset to the ATR patch TGT which was determined at initialization, and change the T/D ratio.
Changing the setting value by 1 will add the offset value by 30 levels to ATR patch TGT.
Use this item for low/high density or fogging images.
Setting range: -4 to 4
[Factory setting value/Value after RAM clear: 0]
P-TG-K Adjust the offset for the target value (Bk-color) of ATR control.
Add the offset to the ATR patch TGT which was determined at initialization, and change the T/D ratio.
Changing the setting value by 1 will add the offset value by 30 levels to ATR patch TGT.
Use this item for low/high density or fogging images.
Setting range: -4 to 4
