Abstract
Abstract In an electrostatographic apparatus wherein toner images are transferred from a first imaging support to a second flexible support with a transfer corona generator, past which said second support is transported on the first support, and wherein an air puffer assists in peeling the second support from the first support by air injection against the second support; the improvement comprising an air baffle positioned between the transfer corona generator and the puffer for impeding the air from said puffer from deflecting the second support adjacent the transfer corona generator, thereby reducing toner smearing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
90 words
In an electrostatographic apparatus wherein image development material is transferred from a first imaging support to a second flexible support with transfer corona means past which said second support is transported on said first support, and wherein a puffer means assists in peeling the second support from the first support by airoform injection against said second support; the improvement comprising baffle means positioned between said transfer corona means and said puffer means for impeding said airoform injection from said puffer means against said second support adjacent said transfer corona means.
Claim 2
Dependent Claim
90 words
In an electrostatographic apparatus wherein image development material is transferred from a first imaging support to a second flexible support with transfer corona means past which said second support is transported on said first support, and wherein a puffer means assists in peeling the second support from the first support by airoform injection against said second support; the improvement comprising baffle means positioned between said transfer corona means and said puffer means for impeding said airoform injection from said puffer means against said second support adjacent said transfer corona means.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1 wheRein said baffle means comprises a flexible shield mounted to said transfer corona means facing said puffer means and extending toward said first support.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1 wherein said baffle means engages said first support for slightly pressing said second support against said first support.
Claim 5
Dependent Claim
16 words
The apparatus of claim 1 wherein said baffle means is a thin insulative air shield plate.
Claim 6
Dependent Claim
45 words
The apparatus of claim 1 wherein said baffle means is a insulative shield mounted adjacent said transfer corona means and extending to closely adjacent said first support for restricting the movement of said second support away from said first support adjacent said transfer corona means.
Claim 7
Dependent Claim
19 words

Claim 8
Dependent Claim
14 words
The apparatus of claim 5 wherein said baffle means is a thin non-metalic plate.
Claim 9
Dependent Claim
23 words
The apparatus of claim 7 wherein said baffle means engages said first support for slightly pressing said second support against said first support.
Claim 10
Dependent Claim
20 words
The apparatus of claim 5 wherein said baffle means is positioned to within approximately 1 millimeter of said first support.
