• Patents include a variable force wiper for printhead maintenance, as well as a multi-port vacuum canister for printhead priming.• Assumed a lead role in collaboration with Asian development team including Taiwanese manufacturing partners as well as Lexmark Cebu (Philippine development partner in Cebu).• Responsible for setting up and troubleshooting problems at a Chinese manufacturing line for parts associated with the fluidic system including developing the final machine functional test.• Designed and controlled the internal specification document utilized by the firmware team to create the control algorithms for general printhead nozzle health and extreme duty recovery requirements.• Teamed with Manufacturing, Quality Assurance, Service, Product Safety, and Marketing to develop the specification for an easily produced, reliable, maintainable, cost effective, and waste reduced ink jet printer design.• Worked on the team responsible for creating the fluidic system for Lexmark’s first off carrier ink system.• Worked with Lexmark’s ink chemistry team to qualify inks for hydrophobic membrane compatibility, including designing experiments, programming a specialized tester, as well as performing testing to ensure this compatibility.• Designed a pressure regulator to protect product’s hydrophobic membranes from damage resulting from the system pump operating pressure.• Designed, built and programmed (Labview) several specialized testers for Lexmark’s Chinese and Filipino manufacturing lines to ensure quality sub-assemblies were being manufactured at each stage of the manufacturing process.• Produced the documentation for designs, part/assembly, functional specifications, risk assessments, and test procedures for various subassemblies.• Worked with our Product Engineering team to diagnose and troubleshoot customer returns from the field and developed firmware and hardware changes to address these issue.

• Worked with development engineers to ensure Inkjet and Laser printers met internal thermal qualification requirements.• Qualified electrical components for required longevity including verifying that certain components followed the Arrhenius equation.• Worked with development engineers to design printers with acceptable thermal characteristics..• Developed a flow tube and software (Visual Basic) to determine system and fan curves, allowing the comparison and optimization of the fans in our systems.• Used Fluent’s Icepak software to model air flow systems to help design features and flow paths to sufficiently cool laser printers.• Used Icepak to analyze the need for forced convection verse natural convection of electronic packages in early stage designs.• Worked with acoustics team to design fan algorithms that sufficiently cooled the system while maintain a minimal acoustic impact to customer experience.
