Abstract: Examples of a mounting device and method are disclosed herein. An example of the mounting device includes a carriage to hold printhead assembly and an interconnect assembly to supply printing composition to the printhead assembly. The mounting device also includes a first latching assembly having an engaged condition to lock the interconnect assembly to a manifold of the printhead assembly and a disengaged condition to unlock the interconnect assembly from the manifold of the printhead assembly. The mounting device additionally includes a second latching assembly having an engaged condition to lock the printhead assembly to the carriage and a disengaged condition to unlock the printhead assembly from the carriage. In this example of the mounting device, the second latching assembly cannot be moved from the engaged condition to the disengaged condition unless the fast latching assembly is in the disengaged condition.

Abstract: Ambient temperature based flow rates can in an example include a setting a flow rate of ink to a printhead mounted in a carriage based on an ambient temperature associated with the printhead, measuring a flow rate of ink to the printhead, and causing a decrease in a velocity of the carriage in response to the flow rate of ink satisfying the threshold flow rate.

Abstract: In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.
