2-1-4 Developing section
The developing section consists of the developing unit and the toner container.
The developing unit consists of the developing roller where a magnetic brush is formed, the doctor blade and the develop-
ing spirals that agitate the toner.
When the toner sensor (TNS) detects a low toner level in the developing unit, the toner replenishment signal is output to
the engine PWB (EPWB). The engine PWB (EPWB) that has received the signal turns on the toner replenishment sole-
noid (TNFSOL) and replenishes toner from the toner container to the developing unit.
Also, the toner container sensor (TCS) checks whether or not toner remains in the toner container.
