I have to explain something here: By Toner we mean a Container/Case + An actual toner powder + RFID chip. With that being said, OKI donor for Xante HWC printer is most likely Pro9541 and/or related series printer.
You can expect:
A) Toner container to be the same except may be a few pins o otherwise fitting preventing devices that can be relatively easy to overcome.
B) Toner powder is obviously identical
C) RFID chip is different, You will need a Xante HWC designated chip otherwise printer will not recognize the cartridge.
So, New OKI Pro series printer would be equivalent toner but NOT direct replacement, You will need a RFID chip specific to Xante and tinker with a box to make it fit, In Xante Ilumina series it takes 3-5 minutes to convert Genuine OKI CX3641 toner in to Xante Ilumina.
