摘要:
A cleaning system for an inkjet printhead comprises an inkjet printhead having an inkjet nozzle array associated therewith. The inkjet printhead is in fluid communication with a first source of a first pressurized fluid. A fluid nozzle associated with the inkjet printhead is in fluid communication with a second source of a second pressurized fluid. The cleaning system further comprises a collection plate. Ink is forcibly ejected from the inkjet printhead by the first source of the first pressurized fluid. A stream of the second pressurized fluid is guided by the fluid nozzle across a surface of the inkjet printhead to direct ink ejected from the inkjet printhead onto the collection plate.

A method of detecting an alignment error includes the steps of controlling a first portion of one or more imaging units to image on a substrate a first plurality of substantially parallel lines extending along a first direction and a second plurality of substantially parallel lines extending along a second direction and controlling a second portion of one or more imaging units to image a third plurality of substantially parallel lines extending along the first direction and a fourth plurality of substantially parallel lines extending along the second direction. One or more distances between adjacent lines of the second plurality of lines are varied and one or more distances between adjacent lines of the fourth plurality of lines are varied. Further, the lines imaged by the first and second portions form an alignment pattern. The method further includes the steps of collecting data relating to the alignment pattern and analyzing the collected data to determine an alignment error between the first and second portions of the one or more imaging units.

A method of printing on a substrate includes the steps of instructing a first imaging unit to print a first image and a registration mark on a substrate contemporaneously during a production run and detecting the registration mark. The method further includes the steps of determining a position on the substrate where a second image is to be printed in accordance with the detection of the registration mark and instructing a second imaging unit to print the second image on the substrate in accordance with the determined position.
摘要:
Apparatus and methods for controlling application of a substance to a substrate involve the use of a functional agent that helps determine the association of a substance with the substrate. The apparatus and methods may utilize jet technology to apply the functional agent directly to the substrate or to an intermediate surface. The substance may be biological substance or a chemical in nature.
摘要:
A printing system deposits a principal substance on a surface and further deposits a gating agent on selectable portions of a print medium. A portion of the principal substance is transferred from the surface to the print medium after the gating agent is applied thereto. The gating agent substantially determines where the principal substance is deposited onto the print medium. A production system and method are also disclosed, as is a production apparatus.

A drying unit includes a frame having an air box mounted thereon, wherein the air box includes an intake port and an exhaust port. A plurality of rollers define a web path within the frame and a heat source is removably attached to the frame, wherein removal of the heat source does not require removal of a web from the web path.
摘要:
A method for printing a print medium applies ink to a surface and ejects drops of an aqueous solution onto the print medium to define image and non-image areas. The ejection of each drop is individually controlled. Ink from the surface is transferred to the image areas of the print medium. Methods of printing on a web and for printing a printed sheet output of a press are also disclosed.

A system for fluid transmission and temperature regulation in an inkjet printing system comprises first and second ink supplies connected via respective first and second valves to an inlet end of a fluid supply conduit. A printhead mount includes an inlet port connected to an outlet end of the fluid supply conduit and an outlet port connected via a first fluid transmission conduit and a third valve to a waste reservoir. A printhead cartridge is mounted within the printhead mount and in fluid communication with the inlet and outlet ports of the printhead mount. A temperature control element and a temperature sensor are each disposed downstream of the first and second valves, and a controller is connected to the temperature control element, the temperature sensor, and to each of the first, second, and third valves.
