Toner Supply Time
Adjusts the toner supply motor on time for sensor supply mode.
This SP is effective only when SP2921 is "0" or "1".
2922*
[0.1 to 5.0 / 0.6 / 0.1 s/step]
Increasing this value increases the toner supply motor on time. So, use a high value if
the user tends to make lots of copies that have a high proportion of black.
Toner Recovery Time
Adjusts the toner supply motor on time during recovery from toner near-end/end.
This SP is effective only when SP2921 is "0", "1", or "2".
2923*
[1 to 60 / 30 / 1 s/step]
Note that toner recovery is done in a 3-second cycle. So, the input value should be a
multiple of 3 (e.g. 3, 6, 9). See "Toner Density Control" for more details.
Toner Supply Ratio
Adjusts the toner supply rate for fixed toner supply mode.
This SP is effective only when SP2921 is "2" or "3".
Increasing this value increases the toner supply motor on time. So, use a high value if
2925*
the user tends to make lots of copies that have a high proportion of black. See "Toner
Density Control" for more details.
[0 to 7 / 0 / 1/step]
0: t, 1: 2t, 2: 4t, 3: 8t, 4: 12t, 5: 16t, 6: On continuously, 7: 0 s
t: 200 ms
Standard Vt DFU
Adjusts Vts (Vt for a new PCU). The TD sensor output is adjusted to this value during the
2926*
TD sensor initial setting process. This SP is effective only when SP2921 is "0", "1", or
"2".
