Latest Patents

One of Cruz's latest inventions is the "Sheet Pre-Transfer Device." This device is designed for electrophotographic printing machines and minimizes impact while delivering a sheet to a photoreceptor at a desired tangential position. The device features a selectively engageable drive nip and a biased baffle member that forms a buckle chamber. Additionally, it includes a series of rollers that provide frictionless directional guidance to the sheet, inducing a predetermined bend for optimal delivery to the photoreceptor. The pretransfer rollers are adjustable, allowing for modifications based on sheet weight or other characteristics. Once the sheet is tacked to the photoreceptor, the disengageable drive nip is released, ensuring that speed mismatches do not pose a problem.

Another significant patent is the "Magnetic Ball-on-Belt Transport." This innovative transport system includes a belt with a steel ball positioned on top, along with a magnet on the back side. The ball forms a nip with the belt, providing necessary normal force against a conveyed sheet, which facilitates easy lateral pulling of sheets to clear jams. The ball is encased in a housing surrounded by a solenoid coil, allowing for the adjustment of nip pressure when current is applied.
