Since 1999 Inkrite have been producing reliable cartridges that have been sold in their millions. Inkrite cartridges are produced under a rigorous ISO 9001 quality management system and every cartridge is tested before it leaves the factory. The chance of an Inkrite cartridge failing is negligible and, in the unlikely event of this happening, you will receive a new replacement cartridge. The high development standard means that Inkrite can also be used in the same printer, in unison, with an original toner. Other toners developed to a lower standard can have too broad a range of particle size and this can effect your printers life cycle and can distort images and colours to unacceptable levels.
