Abstract: Mechanisms for adjusting the position of one or more print heads at an extremely fine resolution (e.g., less than 10 μm) are described herein. The adjustment mechanisms include a differential screw and an indexing wheel through which the differential screw extends. One threaded segment of the differential screw is connected to a threaded feature of a flexible body that is coupled to the print head(s), while another threaded segment of the differential screw is connected to a threaded feature of a rigid body that is coupled to a printer assembly. As the indexing wheel and differential screw rotate, the space between the flexible body and the rigid body changes based on the difference between the pitches of the threaded segments. The adjustment mechanisms described herein utilize the accurate, consistent motion of the flexible body upon experiencing pressure to effect predictable changes in the position of the print head(s).

Abstract: Disclosed is an industrial single-pass inkjet printer/press incorporating an line-scan camera. The line-scan camera enables system software to inspect every sheet for quality assurance purposes. These inspection results are tied back to a digital printer to take one or more of several possible actions. Actions include ensuring a particular number of acceptable prints are generated and sorted. Actions further include performing nozzle checks without pausing or interrupting production orders.

IPC: B41J29/02

Abstract: Techniques for more accurately and efficiently replicating the alignment of one or more printer components with respect to another printer component are described herein. Replication may be achieved by using a fixture and a connection media to create a near exact replica of features of the fixture, or to temporarily hold multiple printer components in position while a joining layer of the connection media hardens. More specifically, a connection media, such as epoxy, can be used to fill an intentionally-established gap between connecting bodies or components that are held in a predetermined position by the replication fixture. The replication fixture represents a mechanical mounting interface that influences the position of a print head (or an array of print heads) within a printer housing or printing mechanism. Joining printer components in such a manner enables a stable mechanical coupling to be formed that does not require post operations.
