The IM4500 in-line pressure sealer by Paitec brings speed, convenience and efficiency to mail processing. The IM4500 will connect directly to most HP and other popular laser printers. Using Jetlink Communication with most printers, the IM4500 will immediately stop printing if a jam should occur. It also features the Automatic Double Feed Diverter system which identifies double feeds or unrecognized sheets and diverts them to a bypass tray.
