VACUUM CLEANING SHOE WITH PLANAR VORTEX AIR FLOW (Cont~d)

This proposal relates to a system 1 for removing residual
material from an imaging surface 2 by means of a vacuum air
flow, The vacuum cleaning head 1 is arranged closely adjacent
to the imaging surface 2 which can comprise a photoreceptor.
A vacuum air flow is created through the vacuum port 3. A
novel port entrance arrangement is provided which produces a

series of vortex air flow patterns, which are in the same
plane as the photoreceptor surface 2, and extend from one end
of the port 3 to the other. The power level required to clean
with this system should be lower than with a vacuum port
design which does not produce such vortex air flow patterns.

The port entrance 3 used to produce the vortex air flow pat~
terns is illustrated in Figures 1 and 2. Grooves 4 are cut
into the normal channel region 5 of the cleaning head 1. More
air enters into the port 3 in the region of the grooves 4 than
in the region of the ungrooved channel 5. The desired vortex
air flow pattern in the same plane as the imaging surface 1 is
produced as shown in Figure 1. Figure 2 shows the apparent air
flow pattern in the grooved channel.
