MSE’s Intelligent Re-Engineering™ approach is the creation of a new benchmark for quality.
It is an evolution beyond traditional re-manufacturing and stands side by side with the OEM. Intelligent Re-Engineering encompasses a Cradle-to-Grave approach to aftermarket toner cartridge production, employing exhaustive Research and Development (R&D) and OEM benchmarking. After benchmarking, MSE creates proprietary and patented production processes, and conducts extensive Quality Control (QC) methodologies and postproduction audit protocols. The end result of these procedures is the market’s best products and a true alternative to the OEM.


Secondary Cleaning System (SCS)MSE’s Solution to Cleaning & Streaking Issues

NSC Printer, Fax and Copier Supplies

The Secondary Cleaning System (SCS) is the embodiment of Intelligent Re-Engineering -- the aftermarket’s first patent-pending invention of a new critical cartridge component not present in the OEM cartridge! The component, a secondary cleaning roller, keeps the PCR thoroughly clean of toner buildup, which transfers to the OPC and paper through the cartridge's life cycle. This innovation virtually eliminates backgrounding, streaking, and dirty print. The results are pristinely clean prints from start to finish! SCS is a scalable technology, and can be employed in multiple cartridges to eliminate these industry-wide issues.
