REG-HS-M
Fine adj M write start pstn: horz scan
Lv.1 Details
To adjust the write start position of magenta color image in the
horizontal scanning direction in smaller increments than 1 pixel.
Use case
When magenta color displacement in the horizontal scanning
direction occurs (smaller than 1 pixel)
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
Caution
Do not use this at the normal service.
Display/adj/set range
-128 to 127
Unit
1/32 pixel
Default value
0

SGNL-Y
Adj Y toner dens tgt VL: initialization
Lv.1 Details
To adjust the offset of the Y-toner density target value to calculate TD
ratio at initialization of the Patch Sensor.
When the value is increased, TD ratio is decreased so that fogging is
alleviated.
When the value is decreased, TD ratio is increased so does density,
but fogging/scattering occurs.
Use case
When checking the value before RAM clear and re-enter it after RAM
clear
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range
-36 to 36
Default value
0
SGNL-M
Adj M toner dens tgt VL: initialization
Lv.1 Details
To adjust the offset of the M-toner density target value to calculate
TD ratio at initialization of the Patch Sensor.
When the value is increased, TD ratio is decreased so that fogging is
alleviated.
When the value is decreased, TD ratio is increased so does density,
but fogging/scattering occurs.
Use case
When checking the value before RAM clear and re-enter it after RAM
clear
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range

SGNL-C
Adj C toner dens tgt VL: initialization
Lv.1 Details
To adjust the offset of the C-toner density target value to calculate
TD ratio at initialization of the Patch Sensor.
When the value is increased, TD ratio is decreased so that fogging is
alleviated.
When the value is decreased, TD ratio is increased so does density,
but fogging/scattering occurs.
Use case
When checking the value before RAM clear and re-enter it after RAM
clear
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range
-36 to 36
Default value
0
SGNL-K
Adj Bk toner dens tgt VL: initialization
Lv.1 Details
To adjust the offset of the Bk-toner density target value to calculate
TD ratio at initialization of the Patch Sensor.
When the value is increased, TD ratio is decreased so that fogging is
alleviated.
When the value is decreased, TD ratio is increased so does density,
but fogging/scattering occurs.
Use case
When checking the value before RAM clear and re-enter it after RAM
clear
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range
-36 to 36
Default value
0
HLMT-PTY
Adj Toner Sensor(Y) dens crrct upr limit
Lv.2 Details
To adjust the upper limit of the target density correction (lower limit of
TD ratio) of the Toner Sensor (Y).
When the value is increased (TD ratio is decreased), fogging/
scattering is alleviated.
Use case
When an image failure (density failure, fogging, carrier adherence,
and scattering, etc.) occurs
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Caution
Take necessary action in accordance with the instructions from the
Quality Support Division.
