How to map network scanner

view story

http://askubuntu.com – I have just bought a shiny new Canon MG6250 multifunction printer/scanner and connected it via LAN. Installing the printing side of things was a breeze, however, I cannot work out how to set up scanning. I installed the MG6200 series ScanGear MP driver from Canon's site but when I open GIMP or Simple Scan, they say there is no scanner detected. Using GIMP's 'update scanner list' button to search for the scanner does not find it. How do I tell Ubuntu, GIMP or Simple Scan to look on the network for the scanner? Is there another utility especially for this? (HowTos)
