hi there, i have a Canon Pixma MP510 all in one inkjet printer. I just connected it my newly purchased Airport Extreme and it is not able to scan. It can print, but it won't scan a document or picture. I've used this all in one for a year being connected to my iMac via USB and no such problem occurred before. Here is the error message i get; cannot communicate with scanner. Cable may be disconnected or scanner may be turned off. check status. scanner. driver will be closed. 101.0.0" i'd appreciate any help i can get. PS: If i do plug it back to my imac via USB it does scan.
