| TK-411 goes to the KM-2050. I'm guessing they're keyed differently, but since the drum is the same, the toner should be the same. We have 1 CS-2550 and the rest KM, but I can't remember if we had to do anything special for it.
You can remove the key plate by poking it out from the top cassette area.
I wouldn't do this trick for putting 2050 toner in a 2550 or vice versa since the 2050 has an OPC drum and the 2550 has an a-Si drum. |
