A fluid-ejection device includes a handheld and/or mountable enclosure, a pneumatic fitting, an electrical connector, and a controller. The pneumatic fitting extends from and/or through the enclosure and is receptive to placement of a tip thereon. The tip contains a supply of fluid, a fluid-ejection mechanism, and an electrical connector for the fluid-ejection mechanism. The electrical connector extends from and/or through the enclosure and is receptive to electrical coupling of the electrical connector of the tip. The controller is situated within the enclosure to cause the tip to eject the fluid via the electrical coupling of the electrical connectors of the tip and the fluid-ejection device.

In an example, a method for automated camera flat fielding and alignment may include determining a magnification of a camera relative to a first camera axis that is generally parallel to a first print media axis by evaluating first and second magnifications between transitions from a first color to a second color on a setup plot. The method may further include determining, by a processor, a rotation of the camera relative to the first camera axis such that the first magnification is approximately equal to the second magnification.

A mounting system for an encoder is disclosed. The mounting system prevents rotation about the encoder shaft's axis of rotation. The mounting system allows translation in a plane perpendicular to the encoder shaft's axis of rotation.

A security apparatus for restricting the opening of a door in a frame consisting of lag bolts screwed into the frame near opposite edges of the door and a nylon belt fastened to each lag bolt. An aperture is formed near each end of the belt and the lag bolts are extended through the apertures in order to fasten the belt to the bolts. The belt can be elongated slightly, and it is preferred that the distance between the apertures is slightly less than the distance between the bolts. Any elongation above a specified amount requires substantially higher force than that required to elongate the belt for putting it in its operable position.
