I recently installed the Pixma TR7550 along with the full set of drivers which include the IJ Scanning utility. The printer is connected to my Windows 7 machine by a USB cable and works fine but when I run the scanning utity I get this message:
Cannot communicate with scanner for these reasons:
- Scanner is turned off.
- (If using Wired LAN connection) It is disconnected from Wired LAN.
- (If using wireless LAN connection) Signal strength is poor due to obstructions.
- Network connection is prohibited by security software.
- Different scanner on the network is selected.
Check the above and try scanning again.
If you still cannot communicate, restart the computer.
Needless to say I have done all of those things but the message continues to appear. I then came across an old Epson scanning utility on my machine and tried that. Guess what, it works absolutely fine. It is old and not as fully featured as the IJ utility but at least I can scan to the computer.
So why would an old Epson utility be able to see my scanner and not the Canon utility??
