A mount maintains a linear assembly, for example an LED printhead assembly, in operative relation to a rotary component whose location and orientation is not always precisely determinable. The mount is particularly useful when the rotary component is routinely removable from the apparatus, for example, if the rotary component is a roller about which is trained a web which must be replaced periodically and upon which the printhead assembly acts. The mount contacts the rotary component restricting movement of the printhead assembly relative to the rotary component about x and y axes generally orthogonal to the primary axis of the rotary component but permits movement of the printhead assembly with the rotary component. The printhead assembly is supported by a mechanism which includes a set of flexure members which in combination both resiliently urge the assembly against the rotary component and also permit its rotation about the x and its y axes and linear movement parallel to all axes while preventing its rotation about the primary axis.
