Review on 🖨️ v4ink Compatible Drum Unit DR420 Replacement for Brother HL-2240 HL-2270DW MFC-7460DN Printer by Sonny Nevers

This imaging drum worked fine for about 6 weeks until I tried it for 2-sided printing. This would leave a somewhat random toner spot extending about half an inch from the top of the page on the front of the page. I discovered the issue after the 30 day return period but it is covered by the manufacturer's warranty. The only problem is that it was only $20 and I had to pay for shipping etc. It's easier to get a new one (other vendors, works great) and keep this one if I'm running longer runs without duplexing. . I think the problem is with the manufacturer warranty and something like this in particular. Your printer will let you know weeks in advance when it's running out of toner, so you can have a replacement on hand but never need it for 30 days. And when you install it, you have to check all its functions. If so, maybe I could replace it for free. Lesson learned!
