The TFS-1000 is a computer-controlled hot-roll fusing system used in toner, media, and fusing system development and quality control. It closely simulates the operating environment of a printer but places the process parameters under user control. This lets you perform fusing experiments quickly, under precisely controlled conditions, and use the results to quantify the effects of each process variable on the degree and quality of fusing. This system is ideal for determining the fusing latitude of a given toner or the range of a process variable within which fusing quality is acceptable for a particular application. The TFS-1000 is also the ideal tool for studying system interactions, including interactions between roller design, toner, media, and roller lubrication under the full range of process conditions.
