We bought 2 sets of Brother TN227 4 High Yield Color Toners as we have two printers that accept them. We installed new toners, all 3 had to be replaced and ran a calibration/test page that had magenta specks all over the printed page and a yellow line across the entire side of the paper. We opened the copier and saw magenta and yellow toner in it, cleaned everything and tried again, same thing. It's like they have runaways! This happened on both copiers and both had the same toners. Do not think that these are really genuine Brother products, they appear to be refurbished and sold as "NEW" ORIGINAL BROTHER TONER.
