Inline Wax Coating Process for Xerographically Prepared MICR Checks

摘要

A process of MICR and non-MICR electrostatic magnetic imaging of two independent electrostatic latent images including a) optionally pre-treating a blank check with a wax-based coating comprising an aqueous polyethylene wax emulsion; (b) forming a first electrostatic latent image in a MICR printing apparatus; (c) developing the first electrostatic latent image by contacting the first electrostatic latent image with a MICR toner to produce a developed MICR toner image; (d) transferring and optionally fusing the developed MICR toner image onto a check; (e) forming a second electrostatic latent image in a non-MICR printing apparatus; (f) developing the second electrostatic latent image by contacting the second electrostatic latent image with a non-MICR toner to produce a developed non-MICR image; (g) transferring the developed non-MICR toner image to the check; (h) fusing the developed MICR toner image and the developed non-MICR toner image to the check, wherein a fuser oil is supplied to the check during fusing; (i) optionally coating the check having fused developed MICR toner image and fused developed non-MICR toner image with a wax-based coating comprising an aqueous polyethylene wax emulsion, and wherein (a) and (i) are mutually exclusive.
