Review on 🖨️ Uniwork Compatible Toner Cartridge Replacement for HP 78A CE278A - High-Quality Printing for Laserjet Pro P1606dn, M1536dnf, P1566, P1560, P1606, M1536 Printer Tray (2 Black) by Sal Muniz

Update March 27: The problem has been traced to a manufacturing defect. (See second photo.) Returning for exchange. Updated rating to 5 stars based on second cartridge performance. HP is crazy about what they expect from a single replacement cartridge. Original Review: Not sure what the problem is, but will update this review if I can resolve this issue in a very short time. I only have until the 30th to return them. I didn't realize that so much time had passed. See attached photo.
