Starter toner cartridges for OKI C330 / C530 cannot be refilled, but non-starter cartridges can be refilled

Question

STARTER toner cartridges for Okidata C330 & C530 (the ones that come with the printer when you first buy it) may slightly differ from non starter cartridges.  These starter cartridges will not have a chip compartment to replace the chip. 

 

If you are refilling a non starter cartridge, you will notice the chip compartment off one of the ends of the cartridge. You can find more information on refilling the this cartridge model at http://www.uni-kit.com/support.htm.
