Review on 🖨️ HP 305X Toner Cartridge, CE410X, Black, High Yield - Compatible with HP LaserJet Pro Color M451, M475, M375nw Series by Larry Willis

I've been buying this toner from Amazon for a while. So I think 1 out of 8 isn't working properly, it's not that bad. I've been using this toner/ink for about half of its lifespan. We always have a spare cartridge. He started to print like in the pictures below. On a phone with HP I'm going through all the steps to clean it up but I couldn't do it. I changed the cartridge and everything is fine. I know these pieces can't always be 100% perfect. But that is my experience with this product. I am by no means an expert on this matter. I believe that many of the problems these days are due to user error. Although hp couldn't help me either. Maybe there is someone who could help.
