The toner collection coil [A], which is rotated by the main motor [B] through the
gears [C], moves used toner from the cleaning unit to the toner collection bottle
[D]. The toner collection bottle capacity is enough to hold used toner from making
1220 m copies. The CPU uses the copy quantity to detect the used toner
overflow. The used toner overflow condition is detected when the copy length
counter (SP52) reaches the used toner detection threshold setting (SP51, Default
value: 1220m). When this condition occurs, "FULL" is indicated in the copy
counter and copying is disabled.
After disposing of the toner in the toner collection bottle and closing the paper
path section, pressing of the Clear Modes/Stand by key should be done by
customers themselves to clear the memory counter for the copy quantity. The
memory for the copy quantity can be cleared using SP53. SP52 shows the length
of copies made since the used toner was emptied. When "0" is input in SP53, the
value of SP52 is cleared.
