Toner Supply Mode
2921*
[0 = Sensor 1 / 1 = Sensor 2 (DFU) / 2 = Fixed 1 (DFU) / 3 = Fixed 2]
Selects the toner supply mode. Under normal conditions this should be set to
2921 1
"0". You can temporarily change this to "3" if the TD sensor is defective. Do not
set to "1" or "2", as these are for design use only (
Toner Supply Time
2922*
[0.1 ~ 5.0 / 0.4 / 0.1 s/step]
Adjusts the toner supply motor ON time for Sensor 1 and Sensor 2 toner supply
mode. Accordingly, this setting is effective only if SP 2921 is set to "0" or "1"
2922 1
Raising this value increases the toner supply motor ON time. Set to a high value
if the user tends to make many copies having high proportions of solid black
image areas (
Toner Recovery Time
2923*
[3 ~ 60 / 30 / 1 s/step]
Adjusts the toner supply motor ON time used during toner recovery from Toner
2923 1 Near End or Toner End. This setting is effective only if SP 2921 is set to "0"
Since toner recovery is carried out in 3-second cycles, the input value should be
a multiple of 3 (3, 6, 9...). (
Toner Supply Rate
2925*
Adjusts the toner supply time for fixed toner supply mode. This setting is
effective only if SP 2921 is set to "2" or "3".[0 ~ 7 / 0]t = 200ms, and settings are
as follows
0 = t , 1 = 2t, 2 = 4t, 3 = 8t, 4 = 12t, 5 = 16t,
2925 1
6 = on continuously, 7 = 0 s
Raising this value increases the toner supply motor ON time. Set to a high value
if the user tends to make many copies having high proportions of solid black
image areas (
Standard Vt
2926*
[0.00 ~ 5.00 / 2.50 / 0.01 V/step] DFU
2926 1
Adjusts Vts (the Vt value for new developer). The TD sensor output is adjusted
