2927 Toner (Near) End Detection
Near End Level
Selects the near end level (Vsp/Vsg). DFU
1
[0.13 to 0.215/0.155/0.005]
A higher setting increases toner, a lower setting increases toner.
This SP sets the level to trigger the toner-near end condition.
Toner Near-End Conditions
• The toner near-end alert is issued if the values of three successive readings of the ID sensor
pattern (Vsp/Vsg) are larger than the Vsp/Vsg pattern selected in SP2927-1.
• After the toner near-end alert is issued it is cancelled immediately if even one of the Vsp/
Vsg readings after the alert is issued is less that the Vsp/Vsg value set in this SP mode.
• The toner near-end alert is issued once again if the values of three successive readings
of the ID sensor pattern (Vsp/Vsg) are larger than the Vsp/Vsg pattern selected in this
SP code.
• After the near-end alert appears on the operation panel screen, prints go through the
machine one at a time (before near-end detection they go through at the default distance
of 1 m).

Toner End Level
After the toner near-end alert has been issued based on the ID sensor pattern readings, if the
2
reading is larger than this SP for three successive readings, the toner end alert is issued and
the machine stops.
[0.15 to 0.235/0.175/0.005]
2928 Toner End Recovery: Recovery Level DFU
Selects the recovery level (Vsp/Vsg).
[0.13 to 0.215/0.155/0.005]
Once the calculated Vsp/Vsg drops below the value of this SP setting, the machine recovers
from the toner-end (or toner near-end) condition.
