The developing unit consists of the developing sleeve where a magnetic brush is formed, the magnetic toner blade and
the developing 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 feed motor (TFM) and
replenishes toner from the toner container to the developing unit.
