Abstract: According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that when executed by the processor, may cause the processor to print a first indicia at a first region on a first side of a print medium. The instructions may also cause the processor to print a second indicia at a second region on the first side of the print medium, in which the second region may be spaced a prescribed distance from the first region along a first edge of the print medium. In some examples, a relative position of the first indicia to the second indicia may correlate to a skew correction value for the first edge of the print medium.

Abstract: According to examples, an apparatus may include a fusing component and a heater disposed in the fusing component. The heater may include a substrate having a first surface and a second surface, a first heating element having a first length attached to the first surface of the substrate, and a second heating element having a second length attached to the second surface of the substrate, the second length differing from the first length.

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.

Abstract: An example system includes a client interface to receive a print job from a client device, wherein the print job includes a user identifier (UID) and a current user location. The example system further includes a controller having an adaptive caching portion to determine that the current user location is a new user location for the UID, identify at least one printer identifier (PID) associated with the new user location, and associate the UID with the new user location and the at least one PID. The system further includes a printer interface to adaptively cache the print job in its entirety at least at one printer corresponding to the at least one PID.

Abstract: 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.

Abstract: An example door lock includes a button with a first region and a second region. The button actuates among multiple positions upon being engaged. A first link member is aligned to the button to detect a state of engagement of a door to a consumables compartment of an electronic device. A sensor is aligned to the button and the first link member to receive a signal from a signal generator based on the state of engagement of the door. A second link member has a first end to align with the button, and a second end to engage the door. A transducer causes the first end to align with the button to disengage the second end from the door upon engagement of the button with the first end.

Abstract: In one example in accordance with the present disclosure a method of is described. According to the method, usage data for an electronic device is obtained. An activity phase from a plurality of activity phases for the electronic device is selected based on the usage data. An activity phase has a corresponding timeout period and is defined by an inter-arrival threshold. The electronic device is instructed to enter a low power mode after being inactive for a time period at least as great as the timeout period corresponding to a selected activity phase.

Abstract: An apparatus operates to provide default services or functionality. The apparatus authenticates replaceable resources by determining whether the replaceable resources originate from a desired source. The apparatus provides an auxiliary service or functionality in addition to the default services or functionality when each of the replaceable resources originates from the desired source, and precludes the auxiliary service or functionality when any of the replaceable resources do not originate from the desired source.
