Descriptions
Waste Toner Collection
The cleaning brush [B] and the cleaning blade [J] removes the toner remaining on
the OPC belt [K] surface. (☛ ! Photocopying Processes – Cleaning – Counter
Blade + Brush)
Toner collection auger 1 [G] moves this toner to the front side, where it is collected
in the waste toner bottle [I].
Toner collection auger 2 [H] levels the toner in the bottle.
The waste toner feeler [E] at the rear of the bottle is gradually lifted as the toner
level in the bottle rises. When the feeler pushes the feeler link [C], the waste toner
full sensor [D] is activated and the machine detects that the bottle is full.
When the bottle becomes full, a message appears on the operation panel. The
machine can make 100 more prints, then further printing is disabled.
The bottle has a cap on the waste toner outlet. Empty the bottle when you visit the
customer.
