Toner Near End is detected by the following 2
systems:
(1) Toner Near End detection by Toner End sensor
(S11-S13). (Definite Toner Near End)
(2) Toner Near End detection by referring to pixel
count and total counts by toner supply motor
(M1-M4) (Estimated Toner Near End)
The Toner Near End detection system is determined
according to the Toner Near End Detection System
(SP3-100-002) setting.
If SP3-100-002 is set to "0": Both detection systems
are applied.
If SP3-100-002 is set to "1": Only (1) is applied.
