HLMT-PTY Toner Dens Sensr(Y) 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 (Y).
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-Y/-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.
