I have an older model color laser printer that a recycling group had brought back to life and replenished with another manufacturerβs generic toner cartridges. The yellow cartridge leaked and smeared on the printouts. I did some research and learned about the excellent reputation of the True Image Tech toner cartridges. The two cartridges I ordered arrived promptly. I immediately installed the True Image yellow cartridge. Perfect! No leaking, no smearing. Iβll definitely order all future cartridges from True Tech.
