Abstract
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.
