An example retaining device includes a retaining feature to retain an article, and a first arm. The first arm projects in a first direction and includes a first protrusion extending away from a first face of the first arm. The first protrusion is to engage another article to retain the retaining device relative to the other article. The first arm includes a second protrusion spaced apart from the first protrusion and extending away from the first face of the first arm. The width of the second protrusion increases in the first direction so as to provide a sloped surface.

Devices for retaining articles

An apparatus is disclosed. The apparatus is to detect an artefact on a printable surface. The apparatus comprises a detection element to engage the printable surface as the printable surface moves relative to the detection element, and to move away from the printable surface when an artefact passes between the detection element and the printable surface. The apparatus also comprises an actuator to be actuated in response to the detection element moving beyond a defined distance from the printable surface. A method and a print apparatus are also disclosed.

Detecting artefacts on printable substrates

A dummy cartridge includes a body having an external shape dimensioned to be received in a cartridge pocket, and a handle integrated into the body, with cavities provided in the body on two opposite sides of the handle; wherein the cavities are dimensioned to allow insertion of a human thumb and/or finger on the two opposite sides of the handle for gripping the handle.
