2965* Toner Pump System Adjustment DFU (B064)
The transportability of toner improves if there is more than the prescribed amount
of toner in the toner unit. In order to achieve this the prescribed amount of toner
must be in the unit. The amount of toner pumped is determined by the amount of
toner consumed, so by adjusting the amount of consumption, the machine can
determine the amount of tone to pump to keep the toner supply unit topped off:
Toner Consumed (g) = Pixel Count x Target Toner Amount
001 Toner Consumption for First Rotation
002 Toner Consumption After First Rotation
003 Pump Clutch On Time
004 Pump Motor On Time
005 Toner Consumed: Rev. Returning to First
006 Amount of Toner Consumed Display
2966* Drum Conditions: Periodic Adjustment (B064 Series)
001 On/Off
Controls if auto process control is done and corona wire cleaning is done at a set
interval.
[0~1/1]
0: On
1: Off
When this setting is on, auto process control and wire cleaning are done
automatically (1) when the main switch is switched off for 24 hours, and (2) after
each copy job.
002 Time Setting
Sets the time interval between automatic adjustments after SP2966 001 is turned
on.
[1~24/1 hour]
2966* Drum Conditions: Periodic Adjustment (B140/B246 Series)
Sets the time interval between automatic adjustments.
[1~24/1 hour]
2967* Developer Density Adjustment Mode
Determines whether the amount of toner is checked during auto process control
with only the TD sensor. With this feature on, the machine uses the TD sensor
only.
[0~1/1]
0: Off
1: On
During auto process control execution after the main switch is turned on, the toner
amount in the development unit is normally checked and adjusted using the ID
sensor. However, in some environments, such as where there could be traces
ammonia in the air, copies could appear dirty or too dark because the ID sensor
reading is not reliable.
