Out of Toner Detection
Toner Sensor output may change when the mixing blade passes above the Toner Sensor. Therefore
the output signal has a max. voltage and min. voltage during mixing blade rotation cycle (4.75 sec.).
E043
If the unit detects Status B, 10 times during printing, the machine recognizes that the remaining toner is
low and the display shows "TONER LOW".
E041
After detecting E043 and the LBP Print Available Counter Value reaches "0" (after 100 pages are
printed), the unit logs E041 (OUT OF TONER).
