I have a Brother HL2240. I installed a new Brother TN450 toner cartridge in July 2015. Now, a year and a half later, the right side of the page prints lighter than the left. I did everything Brother suggested I do...shook cartridge, skid green tab back & forth 15 times, took printer off toner save mode, increased density to darkest #6 setting...problem still exists. You can read the print on the right half of the page, but it is still lighter. Printer reports plenty of drum life and toner...
