E075 is the transfer belt displacement error. Remove the ITB and check if the belt isn`t a little bit to low (marks on the frame) If it is, just correct it, if it happen again, change the frame of the itb.
The problem is in the setup procedures and perhaps your drivers.
Read the manual that came with your printer. It tells you from the start, how to obtain an IP Address from the Wireless Modem to the Printers receiver. Go to Canon for customer support and get the updated drivers for that device.
