Methods and systems for generating a secure copy of content associated with a non-fungible token (NFT) are disclosed. The system will receive a print request to print digital content that is associated with an NFT, access a blockchain to identify a current owner of the NFT, and generate a print job that with instructions to print the NFT content. If and only if the current owner of the NFT is the requesting entity, the system will print a unique authentication code with the digital content. The system will cause a print engine to print the digital content on a substrate or as a 3D object. In some embodiments, the system may be included in a print device that includes the print engine. Other aspects include a system that verifies whether a printed copy of content is an authorized copy, using the unique authentication code and the NFT described above.

An aqueous inkjet printer also ejects drops of UV material on an aqueous ink image and exposes the aqueous ink image and the UV material to UV radiation before passing the aqueous ink image and UV material through a thermal dryer. The exposure to UV radiation pins the UV material to the aqueous ink image and underlying substrate and the thermal dryer fixes the aqueous ink image to the substrate while releasing free radicals from the UV material. Thus, the printer produces textured prints that do not have free radicals that can irritate skin or produce noxious odors.

A printing system comprises printheads to eject ink to a deposition region. Print media are held by vacuum suction against a movable support surface, which moves over a vacuum platen. The vacuum platen comprises platen holes through which the vacuum suction is communicated. An airflow control system comprises airflow zones, each comprising a group of the platen holes, a duct, and a valve, the duct and the valve being arranged to selectively control vacuum suction through the group of the platen holes. For each of the printheads, at least one of the airflow zones is located under the respective printhead. Thus, airflow through platen holes under the printheads can be selectively controlled by selectively controlling the vacuum suction in the airflow zones.

A sheet processing system for automated sheet adjustment includes a sensor system which captures at least a first image of a sheet of print media as the sheet is conveyed on a main transport path between a print media supply module and a marking device of an image rendering module. A control module computes a lateral error for the sheet, based on the captured at least first image, and computes an adjustment based on the computed lateral error. A sheet transport path adjustment mechanism translates a first portion of the main transport path relative to a second portion of the main transport path, based on the computed adjustment.

A method of operating a printer compares print job parameters for a current print job to be printed by the printer to a database of print job parameters for previously performed print jobs to identify media issues that may be caused by printing the current print job at a nominal printhead/media transport path distance. The gap between the printheads and the media transport is adjusted for identified media issues. Additionally, the method evaluates the image data content of the current print job to identify media issues that may arise from the printing of each sheet in the print job. If media issues are identified from the image data content, then the gap between the printheads and the media transport is further adjusted for sheets corresponding to the identified media issues caused by the image data content. An inkjet printer capable of being operated in this manner is also disclosed.

A system and method evaluate defects in printed images. A target image, which has been captured of a printed image, is processed to identify defects, where present, which do not occur in a source image from which the printed image was generated. A trained classification model predicts a defect class for respective regions of the target image, each of the defect classes being drawn from a predefined set of defect classes. For at least one of the identified defects, a measure of severity of the defect is determined, such as a size of the defect. A decision on the acceptability of the printed image is made, based on the measure of severity of the at least one defect and the predicted defect class of a respective one of the regions in which the defect occurs.

An image processing system and method provide for receiving a current print job comprising a set of digital page images to be printed on print media sheets, identifying, for each page image, a set of input parameters, the set of input parameters including one or more of a print media sheet weight, a print media sheet size, a print media sheet thickness, a print media sheet porosity, a print media sheet coating, a print media sheet color, and an area coverage. The method further includes generating an adjustment for each page image, based on the set of input parameters and based on stored magnification errors generated for prior printed pages of print jobs, the adjustment being predicted to reduce at least one magnification error when the page image of the current print job is rendered on print media to form a printed image.

Devices include an inkjet printhead having nozzles and a transport item adjacent the nozzles. The transport item includes vacuum openings adapted to maintain print media on the transport item. The transport item moves the print media in a processing direction. The transport item also includes a jetting area lacking the vacuum openings. The jetting area is elongated and is oriented perpendicular to the processing direction. The nozzles are controlled to eject ink to the jetting area when the nozzles are aligned with the jetting area.

A cleaning pad can be attached onto an inner surface of a transport belt so the cleaning pad can move with the transport belt along hardware of a marking system, including support rollers and a marking platen to remove ink from the marking platen and support rollers of the rendering device as the transport belt cycles through its typical path within the rendering system.

Marking transport cleaning pad

A movable cleaning web can be positioned and allowed to move from a supply spool, between a platen (e.g., vacuum, marking) and the inside of a belt (e.g., marking, transport), into a take-up spool. The cleaning web can move opposite the process direction of the belt. The web can reduce contamination on the platen, inside of belt and along belt rollers.

Cleaning web disposed and operable between marker transport belt and marker platen

A spill proof, user-friendly dispensing system that protects users from exposure to toxic fluids (e.g., Ethylene Glycol used in MICR ink) includes a bottle loading mechanism for feeding ink or other fluids to a respective supply tank of an image forming device, and a quick connect gravity feed multipurpose bottle apparatus. Ink replenishing bottles can be inserted upright into holder of the bottle loading mechanism, connected to a supply tank, and folded back out-of-the-way in a dispensing position. The bottle may be rotated from a gravity feed position to a rotated position for removal and installation while the bottle remains in the holder. The bottle when empty may be used to collect waste from the image forming device.

Multipurpose bottle apparatus and bottle loading mechanism and method

Printer structures include a controller, a marking engine operatively (meaning directly or indirectly) connected to the controller, and a container connected to the marking engine. The marking engine applies marking material to print media, and the container stores that marking material. The container can include a flexible bladder storing the marking material, and an actuator structure operatively connected to the controller. The actuator structure contacts the flexible bladder and periodically moves portions of the bladder to periodically mix the marking material as controlled by the controller (based on the marking engine being idle for a previously established amount of time). Alternatively, the actuator structure contacts the container can periodically rotate the container to periodically mix the marking material as controlled by the controller.

A printing system includes a housing, a track supported by the housing, and a cart which rides along the track. The printing system also includes print heads which eject material onto the cart. To prevent material from inadvertently accumulating on the track and the housing, the cart also includes a wiper configured to wipe the material from at least a portion of the housing. The printing system also includes at least one collection tray configured to direct and/or collect the material wiped from the housing. The printing system further includes a coating applied to outer surfaces of at least some of the elements of the housing, the track, and the cart to further prevent the material from inadvertently accumulating on the track and the housing. The coating can be a siloxyfluorocarbon coating.
