Review on V4INK Compatible 26A Toner Cartridge - Black Ink Replacement for HP Pro M402n M426 Printer by Dean Love

I used to buy from V4INK. Replacement cartridges for my HP402N worked perfectly. I bought two cartridges last July so I don't have to wait for a replacement when my existing cartridge runs out of toner. I opened them up last weekend and found them to be different from my previous V4INK cartridge. There were no problems with the previous cartridge. , BOTH new cartridges give me "Non-HP cartridge" and "No memory found" errors. Checking the cartridges they are different from the one I bought before that worked. As you can see in the images above, they are physically different. The one with the open green reel is the new version. Cheaper! If you have an HP printer, I do not recommend buying from them. I called support a few times on their website. e. He calls and then I get a busy signal. It's a shame they used to be so cheap, but I wouldn't buy them again.
