ISO Standards

Although only adopted by OKI in 2005, the number of Original consumables carrying the ISO Standard has grown significantly. ISO/IEC 19752 now incorporates the majority of our mono printers and fax machines, and we are now expanding this by introducing ISO/IEC 19798 standards for our latest colour printers.    The ISO standard is now accepted by all major Original End Manufacturer's (OEMs) in our industry as the benchmark for measuring toner yields of monochrome consumables.
