In one embodiment, a device for a printer includes a movable tray for supporting a print media. The tray is movable between an open position in which media may be moved on to the tray and a closed position in which media is blocked from moving on to the tray. The device also includes a rotatable media drive component for moving print media on to the tray and a movable restraint operatively connected to the tray. The restraint is movable between: a first position, corresponding to the open position of the tray, in which the restraint does not restrain the media drive component; and a second position, corresponding to the closed position of the tray, in which the restraint restrains rotation of the media drive component.

Media drive restraint and method for detecting a closed media tray

A disclosed example apparatus to install a pen in an imaging device includes a first guide on a first component of the imaging device to guide the pen in a first direction toward a second component of the imaging device during installation of the pen in the imaging device. The example apparatus also includes a second guide on the second component to receive the pen from the first guide during the installation of the pen. The first guide and the second guide define a gap therebetween and at least one of the first and second guides causes the pen to pass the gap without catching. The second guide is to guide the pen into an installed position in the second component.

Media drive restraint

A printer device includes a housing () that defines an interior space. A platform () includes a first position extending along a plane within the interior space for receiving media to be printed with fluid. A mechanism () selectively applies a force to the platform () to move the platform () to a second position at an angle relative to the plane.

Pivotable ink cartridge platform for printer device

Apparatus and method for adjusting and maintaining printhead-to-platen spacing in a printing device, wherein the printing device includes a printhead-carrying carriage and the carriage is pivotally mounted on and reciprocally shiftable along a guide shaft. An anti-rotation rail mounted on a hanger in the printer engages the carriage and determines its position relative to the printer's platen. A clamp structure is connected to the anti-rotation rail and extends through the hanger and is operable for clamping the anti-rotation rail to the hanger. An adjuster mechanism connected to the clamp structure is operable for selectively shifting the anti-rotation rail vertically upwardly or downwardly to position and maintain the carriage, and correspondingly, the printhead a preselected, nominal distance from the platen.
