About Lab Testing & Lab Test Results "Finally, when cartridge re-fillers say 'my cartridges meet or exceed OEM performance', they can say so with absolute certainty." Last December, Toner Refill Supplies, LLC. dba:ColorTonerPlus.com was contacted by three major toner manufacturers to consider carrying their toners. At that time we were buying toner from six other manufacturers. We felt it was time to evaluate both our existing toner line, and the additional sources being offered. The question was, how to fairly evaluate all these toners and verify our choices. The goal was to find toner and component combinations, which would consistently out-perform their OEM equivalents. We then wanted a way to independently verify our choices, so that our customers could purchase these products, with the confidence that our performance claims were absolutely accurate. The NERRR program at the Rochester Institute of Technology was the perfect answer. Over the past several years, our industry has worked with ASTM (American Society for Testing and Materials) and RIT to develop a uniform procedure for evaluating laser toner cartridges by comparing their performance to their OEM counterparts. The key to this testing is that the re-manufactured cartridge is tested at the same time, on the same printer, and under the same environmental conditions as the OEM. The procedure provides for testing of yield, density, clarity and overall consistency of performance. A comprehensive 17-page report is generated, along with a summary of the findings. With so many different brands of toners, drums mag roller sleeves, and PCR’s available we had to devise a procedure to narrow our focus on the toner component portion of the cartridge. We began by testing various drum, MRS and PCR combinations until we found the combination that provided the optimum yield to density ratio. With our basic component structure in place we tested all the toners with the same components on the same printer, and consistent environmental conditions. When we found the toner, which provided the best performance, we tested it with other drums, to insure that we had the right combination. We then submitted cartridges made with these combinations to RIT for independent testing. As of this time, we have RIT results for the EX, 4000, and 4059 toner systems. We have finished our pre-qualification in-house tests on the 2100, NX, and SX and have submitted them to RIT. The AX, LX, PX, and VX have been tested in house, but RIT is not evaluating those cartridges at this time. WX and 8100 are under in-house evaluation. As soon as additional RIT results are completed we will make them available. We are marketing these toners under the name "System Color Matched Toner. When combined with ColorTonerPlus’s new components, (drums, MRS, PCR and blades) cartridges refilled with System Color Matched Toner will provide our customers with a level of performance that is consistent with our RIT test results For the very first time, you can say with confidence, that your cartridges meet and exceed OEM performance. "Finally, when cartridge re-fillers say 'my cartridges meet or exceed OEM performance', they can say so with absolute certainty."
