This remanufactured Hewlett Packard CF361X toner cartridge utilises many of the parts of the original to maintain print quality. The parts of the HP 508X that cannot be reused (or are too worn) are then replaced with high quality compatible components designed to emulate the performance of a brand new cartridge. The completed cartridge is then filled with a compatible cyan toner designed to pass freely through the CF361X toner and fuses at the closest temperature to that produced by you Hewlett Packard printer as possible. This HP 508X cyan toner cartridge is compatible with the very same printers as the genuine article including the HP Colour LaserJet Enterprise M553x.
