Toner Near End Recovery
If the machine detects "Vt < (Vref or Vts) + 4S/5" twice consecutively when in one
of the following situations, the machine leaves the toner near end condition.
• While in the toner recovery cycle (supplying toner on and off for 30 s – see
the previous page) after the machine has detected a toner near end
condition.
• During copying in the toner near end condition.
• If the front cover is opened and closed for more than 10 seconds while a
toner near end condition exists.
Toner End Detection
There are two situations for entering the toner end condition.
• When Vt is level 7 three times consecutively, the machine enters the toner
end condition.
• When "Vt+S > Vt > (Vref or Vts) + 4S/5" is detected in the toner near end
condition, then 50 copies can be made after this condition (the number of
copies between this condition and toner end can be changed using SP2-
213).
Toner End Recovery
If the front cover is opened and closed for 10 seconds while a toner end condition
exists and the toner bottle is replaced, the machine attempts to recover using the
same procedure as for toner near end/end detection.
