HLMT-PTM Toner Dens Sensr(M) dens crrct upr limit
Lv.2 Details To adjust the upper limit of the target density (T/D ratio) adjustment
on the Toner Density Sensor (M).
Density failures and carrier adherence are alleviated when the upper
limit is smaller, and fogging and scattering are alleviated when it is
larger.
The value is returned to 0 if COPIER> FUNCTION> INSTALL>
INISET-M/-4 is executed upon replacement of the developer.
Use case • When adjusting the toner density (T/D ratio) upon occurrence of
density failures, fogging, carrier adherence, and scattering, etc.
• When analyzing the cause of a problem
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.
• Do not use the setting value 11.
Display/adj/set range -2 to 2
-2: +2.0%, -1: +1.0%, 0: +/-0%, 1: -1.0%, 2: -2.0%
Default value 0

Unit
HLMT-PTC Toner Dens Sensr(C) dens crrct upr limit
Lv.2 Details To adjust the upper limit of the target density (T/D ratio) adjustment
on the Toner Density Sensor (C).
Density failures and carrier adherence are alleviated when the upper
limit is smaller, and fogging and scattering are alleviated when it is
larger.

COPIER> ADJUST> DENS
LLMT-PTY Toner Dens Sensr(Y)dens crrct lowr limit
Lv.2 Details To adjust the lower limit of the target density (T/D ratio) adjustment of
the Toner Density Sensor (Y).
If the lower limit is smaller, the density increase can be prevented in
the case of high duty because QM down of developer is restrained,
but carrier adherence gets worse.
The value is returned to 0 if COPIER> FUNCTION> INSTALL>
INISET-Y/-4 is executed upon replacement of the Developing
Assembly.
Use case • When adjusting the toner density (T/D ratio) upon occurrence of
density failures, fogging, carrier adherence, and scattering, etc.
• When analyzing the cause of a problem
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
