OKI ES9476 Was is our Worst Investment

I am an OKI fan , having bought an MB770 mono printers previously, and i thought it wont be different this time around, oh boy was i wrong, I bought FOUR ES9476 OKI Printers at R194 246.40 each, and the machines want a password, we have put in the default 123456 password and it doesn't work, the machine Doesn't recognise LAN cable and further more when you try to print or scan it says warming up. I tried to call OKI for help and was told there is no one to help me. But now we have white elephants in our office. I have even bought an inkjet machine so that we can print.

It was our worst investment by far, almost 800K . I have lost faith in this company
