Black ink cartridge not working on TR4720

dsihfj — Mon, 20 Jan 2025 13:22:05 GMT

The printer was just working fine when I was printing some photos in black and white. Then, the photos started to get light, so I assumed the cartridge was clogged. So, I ran some cleaning cycles, well aware that it probably used up a lot of ink. It still doesn't work. I read that ammonia helps unclog cartridges, so I soaked the bottom of it. Five hours later and still no luck. I put some ink into an old cartridge but that won't print at all either. I think it may be a printer problem as the old one works fine. The color prints well though. I really don't want to waste $30 on another cartridge, so please help me.
