A transform wrapper is stored on a memory device and the memory device may be included in a printer cartridge. The transform wrapper may dynamically build a transform map for a printer based on metadata stored at the memory device. The metadata may indicate at least one of a type of depositing material, transform map, print media and printer.

In one embodiment a print liquid supply apparatus is provided to supply liquid to a liquid needle of a receiving station comprising a liquid container including an at least partially collapsible liquid reservoir an interface structure at a side of the container, including a liquid channel that includes a reservoir connecting portion that fluidically connects to the reservoir and a needle receiving portion to allow the liquid to flow from the reservoir to the needle; a liquid interface of the liquid channel adjacent the needle receiving portion and at a distance from the reservoir connecting portion, a front wall and/or edge adjacent the liquid interface including a push area which is disposed between the liquid interface and the container; and at least one key pen base and key pen protruding from the base in a direction parallel and opposite to the needle insertion direction; and a contact pad array next to the needle receiving liquid channel portion. In another example a sub-assembly of such apparatus is provided.

A physical unclonable function (PUF) apparatus having magnetic particles is disclosed. The magnetic field data and the image view of the magnetic particles in the PUF apparatus are difficult to counterfeit. A PUF apparatus may be incorporated into a user-replaceable supply item for an imaging device. Further, a PUF reader may be incorporated into an imaging device to read the PUF. Other systems are disclosed.

An inkjet recording apparatus configured to perform recording operation by ejecting ink at least from a first recording head, includes an ink tank configured to contain the ink to be supplied to the first recording head, a tube configured to connect the first recording head and the ink tank, and a carriage including a first mounting portion on which the first recording head is mounted, a second mounting portion on which a second recording head is detachably mounted, and a contact portion electrically connected to the second recording head, and configured to reciprocate. A protection member protecting the contact portion can be detachably mounted on the second mounting portion.

An inkjet printing apparatus includes a discharge head that discharges ink, and a housing that contains the discharge head, wherein the housing contains a first ink storage member and a second ink storage member that each store ink, and the ink is supplied from each of the first ink storage member and the second ink storage member to the discharge head, wherein the first ink storage member is an ink cartridge not having an ink refilling port for enabling ink refilling by opening a stopper member, and detachable from the inkjet printing apparatus, and wherein the second ink storage member has the ink refilling port.

A recording apparatus includes an attachment portion not having a storage unit for storing a recording material used for print processing performed by the recording apparatus, and a second control unit configured to operate the recording apparatus in a second print mode in a case where the attachment portion is in a second attachment state in which a second attachment member for protecting a connection terminal is attached to the attachment portion.

It is disclosed a printing agent container having ink an authenticity detection mechanisms comprising: a receptacle having a top wall a bottom wall opposing such top wall and a sidewall between such top wall and such bottom wall; an internal volume defined by such receptacle that contains a printing agent, and a vibration transducer on one of the side walls, wherein the container is to be mechanically coupled to a carriage so that the printing fluid is disposed on the bottom surface, being the vibration transducer to detect a vibration signal induced by the carriage and wherein the container comprises a communication channel to a controller being the controller to receive through the communication channel a container signature from the vibration transducer and to identify a container identification signal associated to the container signature.

A device outputs a first low voltage to a first terminal at a first timing in a period in which a voltage input to a second terminal is a high voltage. After outputting the first low voltage, the device outputs a second high voltage to the first terminal at a second timing in a period in which the voltage input to the second terminal is a low voltage. After outputting the second high voltage, the device outputs a second low voltage to the first terminal at a third timing in a period in which the voltage input to the second terminal is a high voltage.

A liquid container has: a liquid storage section that stores a liquid; a surrounding wall that envelops the liquid storage section; a liquid supply opening formed in the surrounding wall, the liquid supply opening enabling the liquid to be supplied from the liquid storage section to the liquid introducing section; a first storage device that can be electrically coupled to the holder-side terminal through a first contact section; and a second storage device that can be electrically couple to the holder-side terminal through a second contact section. Even when the liquid container is rotated by 180 degrees around the central axis of the liquid supply opening and is mounted in the holder, either of the first storage device and second storage device is coupled to the holder-side terminal. Information about the amount of the liquid is stored in both the first storage device and the second storage device.
