Of course everyone knows that compatible toners are made to be a knock off of an original toner cartridge brand to say the least. But they are also made to fit any brand as undetectable as possible in the prints. The top brand printers also obviously carry the top brand toners as well to match the quality of the machine and make your prints look professional. Before getting into the specific brands, you must understand first that using any compatible toner will effect your environment beneficially. It will greatly reduce waste and pollution as well as conserve resources. This is the best bet for one who is environmentally friendly. Now, Brother of course is a top brand for printers. Brother is especially a top brand for multifunctional printers. So the toners are going to have to match or exceed standards of their users. The machines focus on making the prints move quickly and in turn it is important to have a toner cartridge that is not going to clog or work slower than the machine. That would cause the prints to come out streaky and inadequate. The same goes for Xerox. These industrial sized printers have been popular in the office setting for decades now and will continue to share their great work ethic for years to come. This is one of the reasons that the prints need to look sharp and dark for prints and copies that are done in mass quantities. Cannon printers focus more on the photo quality for the most part. That is why the pigment content has to match exactly to the original cartridges so they can come out the same and stay true to the original prints. They also must appear saturated and deep to appeal to all semi professional photographers needs. Staying true to the original print without being clumpy or spotty is extremely important to the brands that are providing for the customer. If a compatible toner does not work however, it is easy enough to send it back and be reimbursed upon return. This never happens due to the extensive testing that the cartridges go through to even make it on the shelf. Converting to compatible toners is not a mistake in any way. You can have your entire budget, environmental and quality needs taken care of just as the original cartridges would provide and then some. Using a popular high-end brand can't stop you from completing your daily tasks for the price you want.
