Abstract: A fluid ejection device is described. The fluid ejection device has a set of coding elements and a trap element. Each coding element is movable between an initial position and a coded position. The trap element is capable of trapping one or a plurality of the coding elements in the initial position when one or a plurality of other ones of the coding elements is moved from the initial position to the coded position.

Abstract: In an example, a wiper system includes a first wiper blade, a second wiper blade, and a cam. In that example, the cam is coupled to the first wiper blade to move the first wiper blade to a first wipe position when the cam is in a first cam position and coupled to the second wiper blade to move the second wiper blade to a second wipe position when the cam is in a second cam position.

Abstract: A system 9 to determine print fluid ejection nozzle health for a printer device 11 is disclosed. The system 9 comprises an image recording device 5, 5' to record an image 37 of print fluid 35 ejected from a print fluid ejection nozzle 6', 8', 10', 12', 30', 32', 34', 36' and disposed on a printable surface 2, 4, 16, 18. An image processor 7 analyses the image 37 to provide a result based on a characteristic of the image 37 representative of the print fluid 35 disposed on the printable surface 2, 4, 16, 18; and a controller 13 is provided to receive the result and assign a nozzle health category to the print fluid ejection nozzle 6', 8', 10', 12', 30', 32', 34', 36' in dependence on the result.

Abstract: In an example, a wiper system includes a first wiper blade, a second wiper blade, and a liquid dispenser. In that example, the liquid dispenser is oriented to eject liquid towards a cloth area across from the first wiper blade when the first wiper blade is in a rest position and the second wiper blade is in a service position.
