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.

Unlocking consumables

According to an example, a printer may receive an instruction to print a print job of a user and determine parameters of the print job. The printer may perform heuristic analysis of the print job based on the parameters of the print job and previously collected printing heuristic statistics of the user and adjust user printer configurations based on the heuristic analysis.

Heuristic-based acoustic emission and energy conservation

According to an example, an apparatus may include an automatic document feeder, printing components, an externally accessible embedded finishing mechanism, an illumination source to direct attention to the embedded finishing mechanism, and a controller. The controller may determine whether a certain condition has been met pertaining to media sheets fed into the automatic document feeder or printed by the printing components, and in response to a determination that the certain condition has been met, may activate the illumination source.
