HLMT-PTY Adj ATR 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 ATR 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 (switch negative/positive by -/+ key) and
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.
Display/adj/set range -5 to 5
Unit 0.5 %
Default value 0
HLMT-PTM Adj ATR Sensor (M) dens crrct upr limit
Lv.2 Details To adjust the upper limit of the target density correction (lower limit of
TD ratio) of the ATR Sensor (M).
As the value is incremented by 1, the lower limit of TD ratio is
decreased by 0.5 %.
When the value is increased, 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 (switch negative/positive by -/+ key) and
press OK key.
2) Turn OFF/ON the main power switch.
Caution Take necessary action in accordance with the instructions from the

HLMT-PTC Adj ATR Sensor (C) dens crrct upr limit
Lv.2 Details To adjust the upper limit of the target density correction (lower limit of
TD ratio) of the ATR Sensor (C).
As the value is incremented by 1, the lower limit of TD ratio is
decreased by 0.5 %.
When the value is increased, 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 (switch negative/positive by -/+ key) and
press OK key.
2) Turn OFF/ON the main power switch.
Caution Take necessary action in accordance with the instructions from the

LLMT-PTY Adj ATR Sensor (Y)dens crrct lowr limit
Lv.2 Details To adjust the lower limit of the target density correction (upper limit of
TD ratio) of the ATR Sensor (Y).
As the value is decremented by 1, the lower limit of TD ratio is
increased by 0.5 %.
When the value is decreased, density is increased, but fogging/
scattering occurs.
Use case When an image failure (density failure, fogging, carrier adherence,
and scattering, etc.) occurs
Adj/set/operate method 1) Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
2) Turn OFF/ON the main power switch.
Caution Take necessary action in accordance with the instructions from the
