An airborne toner collection manifold for an electrostatographic printer
for coupling in fluid flow communication with a vacuum source includes an
inlet, a collection duct, a first exhaust duct and a second exhaust duct.
The inlet defines a gap slot extending longitudinally between a first end
and a second end. The collection duct is adjacent to the inlet and has a
first end extending longitudinally at least to the first end of the gap
slot of the inlet and a second end extending longitudinally at least to
the second end of the gap slot of the inlet. The collection duct defines
a cavity in fluid flow communication with the gap slot. The first exhaust
duct is in fluid flow communication with the cavity of the collection
duct and is configured to be coupled for fluid flow communication with
the vacuum source. The second exhaust duct is in fluid flow communication
with the cavity of the collection duct and is configured to be coupled
for fluid flow communication with the vacuum source. The second exhaust
duct is displaced from the first exhaust duct and is positioned relative
to the first exhaust duct to be closer to the second end of the
collection duct.
