My Canon Pixima 8220 is not allowing me to scan to USB. When I insert the usb flash drive, the printer says "a USB Flash Drive is connected." When I go to the scan function -> select scan to usb and start the scan I recieve an error that "cannot detect a memory card or USB flash drive for saving." The flash drive is brand new. I have tried other flash drives and have recieved the same message. Anyone else have this issue and figure out how to fix it?
