Toner Near End Recovery

If the machine detects "S/2 < ∆Vt ≤ 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 "4S/5 < ∆Vt ≤ S" 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.
