Abstract: Examples of an apparatus to use in a media feeder and a method to use in a media feeder are disclosed herein. An example of the apparatus includes a platen having an input to receive a medium and an output to eject the medium. The example of the apparatus additional includes a re-feed prevention device including a ramp to deflect the medium away from the input of the platen when the medium exits the output of the platen and a hooked end to catch an edge of the medium when curled as the medium exits the output of the platen.

Abstract: Examples disclosed herein relate to a device including a separator. Examples include a first separator having a surface to contact a medium and is coupled to a first spring. In examples, the first separator has a first centerline in a direction perpendicular to a medium travel direction. Examples include a second separator having a surface to contact a medium and is coupled to a second spring. In examples, the second separator has a second centerline disposed substantially parallel to the first centerline. Examples include a roller to contact the medium to move the medium along the medium travel direction. In examples, the first spring and second spring bias the first separator and second separator towards the roller, respectively. In examples, a force applied by the first separator to the medium is independent of a force applied to the medium by the second separator.

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.

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.
