Title: Innovations by Ivan F Crespo

Introduction

Ivan F Crespo is an accomplished inventor based in Vancouver, WA (US). He has made significant contributions to the field of printing technology, holding a total of 3 patents. His work primarily focuses on enhancing print media handling systems, which has implications for various printing applications.

Latest Patents

One of Crespo's latest patents is the Z-fold print media handling system. This innovative system is designed for printing banners and similar materials using an inkjet printing mechanism that operates without a tractor-feed. The system employs a series of stuttering stopping and starting steps to generate varying static and dynamic frictional forces. This mechanism effectively separates the first sheet of a Z-fold stack from the remainder of the stack. Both conventional cut-sheet media and Z-fold media can be fed using the same printing mechanism, which pulls the media toward a print zone through frictional engagement with the first surface of the media. To prevent printhead crashes and smearing of images near the perforations joining the Z-fold sheets, the printhead to media spacing is increased for Z-fold media compared to the standard spacing used for cut-sheet media. Additionally, a cam feature is incorporated into the media drive clutch disk to determine whether an operator has set a selector lever for cut-sheet or Z-fold printhead to media spacing.
