DEVL-VTH Set low duty toner ejectn image duty VL
Lv.2 Details To set the threshold value of the image duty, which is the condition to
perform the low duty toner ejection sequence.
When any of the average image duty of 4 colors indicates the
threshold value or below, low duty toner ejection sequence is
executed at the paper interval calculated by dividing the value
specified in DEVL-PTH by the value of “threshold value - average
image duty value”.
There are 5 selections for setting value and they changes
automatically depending on the inside temperature.
As the value is larger, coarseness is decreased, but productivity is
lowered and toner consumption is increased.
As the value is smaller, productivity and toner consumption are
improved, but coarseness is worsened.
Use case When printing low duty (low image ratio) images,
• graininess (coarseness) occurs
• low productivity or high toner consumption is pointed out by
the user
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Caution Do not use this when the machine is operating correctly.

DEVL-PTH Set low duty toner ejectn img duty ttlVL
Lv.1 Details To set the total value of the image duty, which is the condition to
perform the low duty toner ejection sequence.
When any of the average image duty of 4 colors indicates the
threshold value or below, low duty toner ejection sequence is
executed at the paper interval calculated by dividing the total value
by the value of “threshold value - average image duty value”. (The
value specified in DEVL-VTH is used as a threshold value.)
Use case While printing low duty (low image ratio) images,
• graininess (coarseness) occurs
• low productivity or high toner consumption is pointed out by
the user
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Caution Do not use this when the machine is operating correctly.
