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