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.
