SGNL-K ATR patch Bk-clr toner dens tgt VL entry
Lv.1 Details 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.
Use case 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
Adj/set/operate method Enter the setting value, and then press OK key.
Caution When INISET-K is executed, the value is rewritten.
Display/adj/set range 0 to 1023
Default value 350 (It may vary by initialization of the Developing Unit when clearing
RAM data.)

HLMT-PTY Adj Y-clr toner dens tgt VL upper limit
Lv.2 Details 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.
Use case When an image failure (density failure, coarseness, fogging, carrier
adherence, scattering, etc.) occurs
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and press
OK key.
Caution Take necessary action in accordance with the instructions from the
Quality Support Division.
Display/adj/set range -4 to 4
Unit 0.5 %
Default value 0

HLMT-PTM Adj M-clr toner dens tgt VL upper limit
Lv.2 Details To adjust the upper limit of the toner density target value of the Toner
Density Sensor (M).
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-PTM.
Use case When an image failure (density failure, coarseness, fogging, carrier
adherence, scattering, etc.) occurs
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and press
OK key.
Caution Take necessary action in accordance with the instructions from the

HLMT-PTC Adj C-clr toner dens tgt VL upper limit
Lv.2 Details To adjust the upper limit of the toner density target value of the Toner
Density Sensor (C).
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-PTC.
Use case When an image failure (density failure, coarseness, fogging, carrier
adherence, scattering, etc.) occurs
