HP Q3675A, Laser Transfer Unit

HP Color LaserJet 4650 Smart Printing Supplies are designed to work together with the HP LaserJet 4600 Printer series as a system for output that's always clear, always sharp. Enhanced pigments and second-generation chemically grown toner particles in all cartridges provide a wide color gamut, consistently accurate color results, and extra sharp black text. Print cartridges are easy to install via front door access, and cartridges are normally the only supplies to replace due to long-life kits.
