Estimating the term…
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.
A document-endorse arrangement having 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 thereat, comprising one or more angled air streams arising from said track wherein each said air stream is directed downstream of said track at an acute angle of approximately 20 degrees with respect thereto, at least one of said airstreams being upstream of said nozzles, said upstream airstream adapted to pneumatically float each said document past said nozzles so as to maintain a prescribed zap between said document and both said track and said nozzles, thereby to inhibit contamination of said nozzle from surplus ink and dust.
