Abstract

An edge guide is provided. A structure includes curved surface over which a print media can travel. The print media includes a first edge and a second edge that is opposite the first edge. A first media guide is contactable with the first edge of the print media. A second media guide is contactable with the second edge of the print media. The second media guide is spaced apart from the first media guide. A relative spacing between the second media guide and the first media guide is adjustable such that a distance between the first media guide and the second media guide is variable. The second media guide includes a mechanism that applies a nesting force to the second edge of the print media to cause the first edge of the print media to move toward and contact the first media guide.

Embodiment Construction

[0055]The present description will be directed in particular to elements forming part of, or cooperating more directly with, apparatus in accordance with the present invention. It is to be understood that elements not specifically shown or described may take various forms well known to those skilled in the art.

[0056]The method and apparatus of the present invention provide a modular approach to the design of a digital printing system, utilizing features and principles of exact constraint for transporting continuously moving web print media past one or more digital printheads, such as inkjet printheads. The apparatus and method of the present invention are particularly well suited for printing apparatus that provide non-contact application of ink or other colorant onto a continuously moving medium. The printhead of the present invention selectively moistens at least some portion of the media as it courses through the printing system, but without the need to make contact with the prin...
