Toner Low Condition (At warming-up,A4 transverse:16ppm *1)

t1

TNRSNS

t1 1.12

T=2.3

When the toner low condition is detected 20 consecutive times, toner low is detected.

(The toner low message is displayed when about 1000 A4 sheets at 5% density have been printed after toner low had been detected.)

The detection is not performed until toner low occurs after the detection of toner low.

When the toner full condition is detected 10 consecutive times, toner low is removed.

When the toner sensor remains unchanged for more than 15 cycles of 2.3 seconds, the toner sensor alarm is activated.

The toner sensor does not perform the detection while the drum motor is not running.

* 16ppm is the print speed at warm-up. T and t1 change in proportion to the print speed.
