Appl. No.:

17/331262

Inventors:

- Norwalk CT, US
Christopher D. Atwood - Webster NY, US
Frank B. Tamarez Gomez - Webster NY, US
Jacob McCarthy - Williamson NY, US

International Classification:

B41M 5/00
B41J 2/145

B41J 13/00
B41M 7/00

Abstract:

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.

Abstract:

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.

B41J 25/308

Abstract:

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.

Abstract:

A method operates a three-dimensional (3D) metal object manufacturing system to maintain a temperature of an uppermost layer of a 3D metal object being formed within a temperature range conducive for bonding between the uppermost layer and a next layer to be formed. A controller of the system compares a temperature of the uppermost layer with at least a low end temperature of the temperature range and operates an electrical resistance switching network using 3D model data to provide electrical power selectively to heating elements in a modular heater to heat the 3D metal object being formed when the temperature indicated by the signal from the sensor is less than the predetermined temperature.

International Classification:

B22D 23/00
B33Y 10/00
B33Y 30/00

Abstract:

A three-dimensional printing system includes a build platform comprising a build surface. The printing system also includes an enclosure system having a side portion extending entirely around the build surface, a top plate portion that abuts the side portion, and a bottom portion. The side portion, the top plate portion and the bottom portion form an enclosed space surrounding the build surface. The top plate portion is moveable so as to adjust a volume of the enclosed space. A 3D printer printhead is disposed adjacent to the enclosure system for depositing a print material onto the build surface. The printing system also includes a heating system for heating the enclosed space.

Abstract:

A method of printing on fabric includes: (a) loading a thermoplastic material into a nozzle of an extruder, such as an extruder of a three dimensional (3D) printer; (b) positioning a substrate that includes fabric in a print area proximate to the nozzle; (c) heating the thermoplastic material in the nozzle to a temperature that is equal to or greater than a melting point temperature of the fabric; and (d) extruding the heated thermoplastic material from the nozzle as a filament onto the fabric to yield a printed pattern on the fabric.

Abstract:

An image forming apparatus includes a collection system for collecting vapor co-solvents that are a byproduct of liquid ink. In addition, the collection system collects dew condensation from the moist air that is generated by lamps that dry the ink on a substrate. The collection system can be located in an exhaust passage. A condenser is installed in parallel and in front of an exhaust fan in the exhaust passage. The exhaust fan directs a flow of air through the exhaust passage. The collection system also includes a removable waste bottle for collecting the dew condensation and the condensed co-solvents. The exhaust passage bifurcates into an exhaust duct that is located after the exhaust fan and which discharges dry air and a collection channel that is located in front of the exhaust fan and which carries liquid drip off to the removable waste bottle.

Abstract:

A media handling assembly contains a transport path for driving a document sheet downstream in a process direction. A first side edge extends lengthwise along the process direction. A registration guide edge extends lengthwise along the process direction and is situated opposite the first side edge. The media handling assembly includes at least one nozzle that is arranged proximate the first side edge. The at least one nozzle selectively discharges an airstream transverse the process direction towards the registration guide edge. The airstream drives the sheet against the registration edge guide for side registering and deskewing of the sheet.
