Well - it may not be so simple, i will explain... These printers as well as majority printers sold today, have RFID chips in them that programmed to work with this particular printer only. Yes, despite slight physical difference that can be easily defeated, toner cartridge for C9600 is the same as your intec and you plan on using aftermarket toner, it will be just as good or just as bad for the intec as it is for your OKI. The problem is - once printer detect "toner low" it will go in to "toner empty" soon and will stop operating and there is no way to revive the chip and sadly unlike for many other printers there are no aftermarket chips for intec where there are plenty for okis. Another issue - there might be a different chip in toners sold in US and other countries so lets say these toners are $250 in USA but they, once again, may not work in AU version of this printer - this I am not sure for 100% but OKI - who make these engines do program their printers differently for Japan's, US and Europe's market and toners are marketed differently, like in Europe, for example, they may not offer a choice of low and high yield cartridges, instead sell only something that in the middle.... I just remebered - the newer OKIs use HD toner so if plan to go generic - get toner that suitable for OKI ES-3640, C9850, CX3640. Please keep in mind that if your service dealer will find out that there was generic toner used in this printer - they will, most likely, drop drop your warranty. I have an intec dealer that I am friendly with here in USA, I will try ask them how much the toners are - may be if there is enough of the difference to justify cost of the shipping and investment to buy ahead... Well, i will ask and you decide.
