Toner End Recovery
„
If the front cover is opened and closed during toner
near-end/end:
z
The toner supply motor turns on for 1.1 s
z
Then the toner supply clutch turns on for 1 s
„
Then, if the toner end sensor detects toner:
z
The machine compares the current TD sensor
output (V
T
) with the reference voltage (V
REF
).
z
If V
T
is less than or equal to V
REF
, there is enough
toner. Toner near-end/end is cleared.
z
If V
T
is more than V
REF
, the clutch turns on again. If
still no good after 7 attempts, toner near-end/end
remains.

The machine uses the TD sensor to determine whether the toner concentration has
risen sufficiently.

The slide summarizes this procedure.
