Review on Brother WT 100CL Waste HL 4040CN HL 4070CDW by Bob Kandravi

I've been using this Brother laser printer for over ten years and have only replaced the cartridges once. I thought the waste toner box might be full when it started working sporadically. I got advice online from a YouTube video explaining how to put a small piece of tape on the hatch at the back of the car and I'm back in business. A waste toner bag and a great tip from a YouTuber saved me hundreds of dollars in repairs and parts.
