<Toner Replenishing Control>
When the copier determines that toner replenishing is to be carried out
based on the ATDC output voltages, M15 is controlled by the signal
output from pin 70 of IC4A on PWB-A.
For the timing at which M15 is energized (toner replenishing timing) and
the period of time during which M15 is kept energized (toner
replenishing time), see 13-5. ATDC Sensor.

PC Drum Drive Motor M5 is energized.
Toner supplied from the Main Hopper is conveyed by the Sub Hopper
Toner Conveying Screw and fed at the center of the screw to the Sub
Hopper (Sub Hopper Toner Agitating Lever).
The Sub Hopper Toner Agitating Lever evens out the toner towards the
front and rear, while agitating it. Toner is then fed under the Toner
Regulator onto the Sub Hopper Toner Replenishing Roller.
Sub Hopper Toner Replenishing Motor M15 is energized.
The Sub Hopper Toner Replenishing Roller is turned by a gear train to
feed toner into the Developer Mixing Chamber.
