A printer housing assembly provides dual in-line cartridges separated by a pre-set distance. Drive belts are used to pass documents such as checks at a high rate of speed past the nozzles of the dual cartridges. A delayed firing mechanism is provided between the two cartridges so that each cartridge will print exactly the same marking on the same spot of each document as it passes by. Further enhancements and contrast quality can also be developed by use of multiple cartridges more than just two cartridges which are placed in a specialized phased relationship to develop &ldquo;dot-on-dot&rdquo; printing of the same target by each individual cartridge.

System and method for high quality bank check imprintation during high velocity passage of bank checks

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

Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means.

Ribbon tracking technique with low-ribbon detection

Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means and a transport control arrangement for advancing checks past processing stations according to one or several 'velocity-profiles', depending upon the type and/or condition of the check.

Selectible transport-servo velocity profile for document transport

Document transport control including document velocity profiles

Disclosed are 'anti-wander' web-transport arrangements wherein web-means are intermittently advanced, while being monitored for misalignment along the transport-path, and also being automatically urged back into proper alignment along this path.

Servo for controlling document transport

Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means including a pair of area-photo-sensor means, one on each side of the check whereby the differential output thereof indicates 'degree of skew'.

Document-skew detection with photosensors

'Anti-wander' web-transport arrangements wherein web-means are intermittently advanced, while being monitored for misalignment along the transport-path, and also being automatically urged back into proper alignment along this path. Preferably, this is done with left and right roll means, one of which is selectively urged more tightly against the web to impart superior advance-thrust and so urge the web back into proper alignment.
