My brother printer Mfc 490 cw connects to my home network, via wizard, no problem. But when I hit scann button, it say " check connection" . Also, I cannot print or scann from my iPad. I have I print and scan app,, where I have selected this printer in settings. My iPad is connected to the same network as my printer. I have tried to return printer to factory settings, and connect to network again, but it didn't solve the problem. Any ideas how to fix this? Thanks in advance. P.S. this is wi if enabled printer.
