Problems solved by technology

This unevenness can present a problem for printing substrates to stack in the tray when the substrate fills the output tray, and the degree of unevenness of the substrate surface can affect the desirability of the printed paper to the user

Embodiment Construction

[0014] figure 1 A block diagram of an aqueous printing system 100 is shown that is configured to maintain the flatness of the printed substrate while drying the aqueous ink image printed on the substrate. Although the system 100 is an aqueous printing system and is used to illustrate the structure and principles of operation of the substrate cooler 112, the cooler of the printer can also be used to use, for example, ink emulsions, inks made with other solvents, pigmented inks, ultraviolet (UV) ) printers that use curable inks, gel inks, solid inks, and other types of inks, as well as printers (such as xerography) that use toners and other marking materials to form images on substrates. As used herein, the term "imaging system" refers to any system that uses any type of marking material to form an image on a substrate. Thus, while the exemplary system 100 described below includes an inkjet printhead, other types of components can also be used to form images on substrates using...

Abstract

The present invention is entitled "Printer and Substrate Cooler for Maintaining Flatness of Substrates Printed in Inkjet Printers". The present invention discloses an imaging system comprising a substrate cooler that reduces the temperature of a substrate bearing a dried ink image. The substrate cooler has a plurality of rollers, at least one actuator operably connected to the plurality of rollers, and a controller operably connected to the at least one actuator. The controller is configured to operate the at least one actuator to move the rollers relative to each other to vary the length of the path along which the substrate moves through the substrate cooler.

Description

technical field [0001] The present disclosure relates generally to aqueous inkjet printing systems and, more particularly, to media handling systems in such printers. Background technique [0002] Known aqueous inkjet printing systems print images on substrates. Whether the image is printed directly onto the substrate or transferred from an overlay disposed around the intermediate transfer member, once the image is on the substrate, the moisture and other solvents in the ink must be substantially removed from the surface to secure the image to the substrate. The dryer is typically positioned after transferring the image from the overlay or after printing the image on the substrate to remove moisture and solvents. To enable the printer to operate at relatively high speeds, in some cases, the dryer uniformly heats the entire substrate and ink to temperatures typically reaching 100°C and up to 140°C. As the dried substrates are moved through the printer on the media transport...
