Password for DCP-L2540DW firmware update

Trying to update firmware on DCP-L2540DW and it asks for password.

Looked behind the printer, there is only rectangular Serial Number sticker and manufacture date July 2014. Cannot find anything saying "PWD". No other sticker around the printer either.

Tried also printing Network Configuration and WLAN settings - no signs of password.

This is first time I am trying to update firmware, default "initpass" or "access" passwords do not work (see image below)
