Remanufactured C4194A Yellow Toner Cartridge (HP 640A)

Remanufacturing plays important role in saving natural resources and environmental protection. It takes a fraction of the energy to remanufacture a cartridge compared to making a new one. Besides, any part in the toner cartridge can be replaced allowing the cartridge to be used almost endlessly, thereby conserving our natural resources.

• The first step is the collection of the empty OEM HP C4194A toner cartridge. Such cartridges are either purchased or obtained through a donation program our company conduct;
• The very remanufacturing process begins with the initial examination. We test empty OEM HP C4194A toner cartridge, dissemble and scan it for signs of flaws and wear;
• The corona wire and waste toner collector are thoroughly inspected, cleaned and tested.
• The toner of Remanufactured C4194A is replaced with new one from an individual bottle. We also replace the retainer blade and scraper blade;
• Dianippon Super Resolution OPC Drum lubricated with a non-toxic chemical powder replaces all OPC (Optical Photo Conductor) to produce darker clarity in your print;
• We assemble every unit manually using new replacement parts (including Doctor Blade, Recovery Blade, Wiper Blade, Drum, Mag Roller, PCR, Toner) to guarantee excellent standards of clarity and print. The shell of the Remanufactured C4194A toner cartridge lasts indefinitely and may be used over and over again, with no effect on the level of performance of the cartridge;
• Before final packaging and dispatch, our qualified personnel carefully conduct testing of every cartridge.

We provide a lifetime warranty for our products!
