I've been using the 920wt for about 3 years and love it ... other than the high price of the toner.
Recently, I've found a supplier in Germany who sells original OKI toner at a price that, even after shipping, is better than $100 less than that sold in the US.
The issue I'm having is that the part number on the German toner is different from the part number on that sold in the US. When I check, the German toner shows in searches as correct for the OKI 920wt.
Does anyone know if there is a difference in the printer itself that will prevent it from recognizing the German toner cartridge? I know that the cartridges are chipped.
