My printer is printing pages with very faded/light ink. I've replaced the toner cartridge, but the problem still persists. I'm not too familiar with printers, but after some research, I tried opening the front door during a job and after removing the cartridge, it looks like the ink is faded before the fuser. It is a compatible toner cartridge, so I'm wondering if the generic cartridge is the problem. Any help as to how to test what the problem is would be a great help. Thanks
