DEVL-THC Set toner ejectn img duty threshold (C)
Lv.2 Details To set the threshold value for average image ratio where C-toner
ejection is executed.
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 While printing low duty (low image ratio) images,- When graininess
(coarseness) or decrease in density occurs- When low productivity
or high toner consumption is pointed out by the user
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
Caution Do not use this when the machine is operating correctly.
Display/adj/set range -2 to 5
-2: -0.2, -1: -0.1, 0: 0, 1: +0.5, 2: +1.0, 3: +1.5, 4: +2.0, 5: +3.0
Default value 0
DEVL-THK Set toner ejectn img duty threshold (Bk)
Lv.2 Details To set the threshold value for average image ratio where Bk-toner
ejection is executed.
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 While printing low duty (low image ratio) images,- When graininess
(coarseness) or decrease in density occurs- When low productivity
or high toner consumption is pointed out by the user

TNNEWCNT Set of new Toner Container check times
Lv.2 Details To set the number of times to execute the new Toner Container
check sequence.
As the value is larger, whether the Toner Container is a new one can
be checked accurately regardless of the period of time the container
is being left, but downtime is increased.
Use case - When the user pointed out that the Toner Container is not
recognized as a new one although it is replaced
- When the amount of downtime is pointed out by the user
Adj/set/operate method Enter the setting value, and then press OK key.
Caution Do not use this when the machine is operating correctly.
Display/adj/set range 3 to 10
3: 3 times, 4: 4 times, 5: 5 times, 6: 6 times, 7: 7 times, 8: 8 times, 9:
9 times, 10: 10 times
Unit 1 time
Default value 7
TNENDCNT Setting of number of toner level check
Lv.2 Details To set the number of times to execute the toner level check
sequence.
As the value is larger, the accuracy in toner level detection is
increased because the toner level is checked more frequently, but
downtime is increased.
Use case - When the user pointed out that the actual toner level is much higher
than the estimated toner level
- When the amount of downtime is pointed out by the user
Adj/set/operate method Enter the setting value, and then press OK key.
Caution Do not use this when the machine is operating correctly.
Display/adj/set range 1 to 5
1: 1 time, 2: 2 times, 3: 3 times, 4: 4 times, 5: 5 times
Unit 1 time
Default value 2

Lv.2 Details To form dot patterns to control the occurrence of horizontal lines
when they appear at 47/96 mm intervals.
Use case When horizontal lines appear at 47/96 mm intervals
Adj/set/operate method Enter the setting value, and then press OK key.
