2986 Refresh Mode
This SP code is used periodically to discard toner in the developer/toner mixture and
replenish it with fresh toner. Over a long period of time the quality of the toner in the
developer/toner mixture may deteriorate. This can occur with machines that are used
infrequently or on machines where the average copy or print is of very low density.
001 Interval
Sets the interval between refresh executions. The toner refresh is done when the count
exceeds this number.
[0~25/0/1 K]
Note:
• "KMAI" Means K sheets (1,000 sheets).
• The machine will execute the refresh mode immediately as soon as the count exceeds
this setting, even if this occurs during a print job.
When the count is exceeded during a print job the job will pause and a message tell the
operator to wait while the machine makes the adjustment.
002 Level
Selects the Vsp value that will trigger toner refresh. Toner is refreshed if the value of Vsp
drops below the selected level.
[0~4/2/ 1]
0: Vsp = 0.8
1: Vsp = 1.0
2: Vsp = 1.2
3: Vsp = 1.5
4: Vsp = 1.8
Note: Vsp is the ID sensor output after it measures the toner density of the ID sensor
pattern.
003 Repetitions
Sets the number of times the refresh cycle is repeated for one refresh execution.
[1~3/2/1 times]
2990 Adjust Start Timing
This SP adjusts the timing of the first copy or print to ensure the quality of the first copy.
Clean toner is occasionally consumed when the drum starts to rotate. This can lead to
poor cleaning and other poor conditions on the drum.
[0~2/0/1]
0: Normal timing
1: Timing Adjustment 1. The transfer belt separation from the drum is delayed for the
1st rotation of the drum to keep the belt against the drum in order to counter the effects
of a possible faulty reading by the drum potential sensor.
2: Timing Adjustment 2. The transfer belt separation from the drum is delayed for two
drum rotations to keep the belt against the drum to counter the effects of faulty readings
by the drum potential sensor or poor drum cleaning.
