A document-endorse arrangement has a document transport mechanism wherein documents are advanced down a track past one or more print stations where a jet-print nozzle array projects an ink stream to the document. One or more angled air streams arise from the track. Each air stream is directed downstream of the track at an acute angle of approximately 20 degrees with respect to the track. At least one of the airstreams is upstream of the nozzles and is adapted to pneumatically float each document past the nozzles so as to maintain a prescribed gap between the document and both the track and nozzles. This inhibits contamination of the nozzle from surplus ink and dust.

Angled air impingment system for document control

In a document processing array, an imaging/illumination arrangement for illuminating and imaging the documents at one or several imaging-sites as they are rapidly transported there-past, each site having, as its illumination source, a hollow Lambertian integrating cylinder housing lamps which project essentially all their light onto the inner cylinder walls to be reflected/diffused thereby in Lambertian fashion and sent to the imaging site(s).

Illumination system

In a check processing array, an imaging/illumination arrangement for illuminating and imaging checks at one or several imaging sites as they are rapidly, continuously transported past two or more imaging stations, each station having, as its illumination source, a hollow Lambertian integrating vessel, housing lamps which project a highly uniform, diffuse Lambertian illumination-beam to its respective imaging site.
