When a media tray is inserted into a printer with the leading edge of the printed page going into the printer first, multiple sheets of media may slide off the media stack (“shingle”) into the paper path if the primary input tray is inserted too aggressively. This may result in double feeds and/or paper jams for the user. Disclosed is a mechanism that is transparent to the user for slow speed tray insertions but provides force feedback to the user indicating tray insertion at too high of speed. If the user inserts the tray below the speed threshold, then the result is a normal tray insertion. If the user inserts the paper tray above the speed threshold, then there is a feedback to the user to slow the tray insertion to an acceptable velocity.

POWER CONTROL FOR HAIR IRON HAVING CERAMIC HEATERS
A hair iron includes two longitudinally extending arms each having a ceramic heater. Users place hair between the heaters during use. A controller coordinates heating conditions of the heaters. If a line voltage supplied to the hair iron is a high voltage, the controller is configured to alternate heating between the heaters whereby only heating of one heater occurs at one time. To reduce flicker and harmonics, the controller supplies heating current so that one heater remains off for consecutive half-cycles of alternating current while the other heater is powered on variously. The controller then switches the heating. The hair iron further includes a line voltage detector to detect whether a line voltage supplied through a cord to the hair iron is either low voltage or high voltage. During such time, the controller limits heating power to the two heaters.

AUTHENTICATION USING MAGNETIC FIELD BASED ON CURRENT DRAWN BY SECURITY DEVICE
A method for determining authenticity of a security device of a component in an imaging device includes receiving, by the security device, an authentication challenge including one or more commands and executing, by the security device, the one or more commands in response to receiving the authentication challenge. A magnetic field profile is generated based on current drawn by the security device from a power source while the security device is executing the one or more commands, the generated magnetic field profile indicating an authentication response of the security device to the authentication challenge for use in determining authenticity of the security device.

A sorter processes trading cards in an affordable, accurate, and easy-to-use manner. The sorter includes an input and output bin. A transport path moves cards between the bins and has two scan bars, one above and one below the path. The scan bars capture an image of a top and bottom surface of ones of the cards. A controller coordinates movement of the cards along the path and receives the image for processing. Users interact with the controller by way of an interface to influence the processing. The sorter also includes a coil to detect metal foil on the cards. Other embodiments are envisioned.
An imaging device has a fuser assembly and a removably insertable cartridge with an activation device. The fuser assembly has a fusing nip that heats during use. A shutter moves between a fully opened and fully closed position to allow or block access to the fusing nip. A frame has an opening to allow passage of the activation device of the cartridge. During use, the shutter blocks access to the fusing nip until the activation device of the cartridge passes through the opening of the frame and contacts a corresponding activation surface, whereby the shutter begins opening and travels through a range of movement until reaching the fully opened position when the cartridge is fully inserted into the imaging device. Removal of the cartridge reverses the action of the shutter.
The invention adds a Physical Information Layer (“PIL”) to the magnetic particles within a matrix that creates an unclonable physical unclonable function “object.” The PIL assists in searching to find the combination that matches a pre-determined enrolled combination with additional information that includes a search index, which limits the range of data required to search in order to find a match in the enrolled database. The index could be a predetermined value that associates the random magnetic profile values to a list of enrolled values in a database. The additional information may include product or general information that needs to be easily communicated to a user of the PUF.

A system includes a spool directory accessible by a mobile computing device and an imaging device. A user selects for imaging on the imaging device a file accessible by the mobile computing device. The mobile computing device saves the file on the spool directory with a unique name. Upon the user accessing the imaging device for imaging, the imaging device generates a unique quick response code. The user captures the code with a camera of the mobile computing device and the code is used by the mobile computing device to rename the file on the spool directory. That the imaging device knows the quick response code, the imaging device accesses and prints the file on media for the user.

A method of determining authenticity of a component in an imaging device includes generating an analog signal as an authentication challenge to the component. The method further includes generating, by the component, a response to the authentication challenge by converting the analog signal into one or more digital values and capturing a derivative of the one or more digital values as the response. Authenticity of the component is determined by comparing the response with an expected response.

A reusable media shell has a frame to hold sheets of media in an interior. A removable cap connects to the frame and its manipulation unveils the media for picking by an imaging device. The cap resides on a terminal end of the frame so the frame covers a majority of the media. A lift plate in the interior forces upward the sheets for picking. Two magnets on the frame magnetically secure the frame to magnets in a base of the imaging device and position the sheets in the base. Upstanding walls, a lid and bottom define the interior of the frame. Inserts attached to the walls allow adjustment to accommodate various sizes of the media.
