Toshiba E-Studio 3511 / 4511 firmware

[nemo]

Hi! I`m new in photocopiers and stuff like this, but i have some questions :
- can anyone tell me, for example how can i reset the administrator password on a toshiba studio 3511
- how can i upgrade the firmware?
- and where can i download the firmware, cause the company where i work has bought the Toshiba used , and i dont know what should i do to change the language (i can change it, but after the reboot it turns back to german ) and config for network usage.

For the moment these were my questions .

Thanks in advance
