A recording device includes a first cover that is movable with respect to a recording unit that performs recording on a sheet, and that moves to a first open position for opening a space where the recording medium to be recorded by the recording unit is transported, and to a first closed position for closing the space, and a second cover movable with respect to the first cover. A movement direction of the first cover includes the same directional component as a movement direction of the second cover with respect to the recording unit, and a first coupling portion that couples the first cover and the second cover is provided in the recording device.

A printer includes a body configured to accommodate recording paper, a lid attached to the body to be openable and closable relative to the body, a pressing part on the lid, a platen roller attached to the lid, a movable shaft in the body, a spring that urges the movable shaft, and a lever configured to support bearings of the platen roller with the lid being closed. The movable shaft is provided at a position corresponding to the pressing part to be movable in a longitudinal direction of the movable shaft, and is pressed by the pressing part to generate a spring force in the spring during closure of the lid.

Examples disclosed herein relate to unlocking consumables of imaging devices. Example imaging devices include a lock to secure a consumable to the imaging device. A feedback engine of the imaging device may selectively generate a signal in response to an actuation event to control a component to indicate the consumable is secured. A lock control engine of the imaging device may determine if the actuation event is approved to unlock the consumable. A release engine of the imaging device may disengage the lock in response to approval of the actuation event.

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.

A method of engaging a supply module with a printhead includes the steps of: moving an actuator handle in a first motion along a first axis, thereby linearly sliding the supply module along the first axis towards the printhead and engaging ink couplings of the supply module with complementary ink ports of the printhead; and moving the actuator handle in a separate second motion along a second axis perpendicular to the first axis, thereby moving a PCB of the supply module towards the printhead and engaging PCB contacts with complementary printhead contacts.
