Error message




By yupper on Jul 04, 2008

" "
after installing the driver and software, then installing the hardware, when I try to scan I get the error message that says Can not communicate with scanner. cable disconnected or power not on. this is a usb powered device, so the problem is one in the same. all other usb devices I have work, but they have external power supplies, and my digital camera downloads to the computer fine.

Cannon Tech support could not help me. How about You

- the software is arcsoft photo studio 5.5, the os is XP home and the device manager recognizes the scanner witch is cannon canoscan lide 90. I can only assume it is a twain driver.


they have sent me a replacement due 7/11 I hope it works, as I believe it was a mechanical problem. we will see.

Thank you for the responce

What is your operating system?

If XP, check your device manager to see if the scanner is being recognized by XP.

What is your scanning software?
Try to use another scan program ( a free demo version should work fine.)

Are you using TWAIN or an ISIS driver? If it is a TWAIN driver, then any Photo editing program should be able to connect ( usuallly!?).

- I am confused. Exactly what model scanner is this?

- Some pc's ( some Dells) have a problem supplying enough power to the USB bus. Some devices may not connect correctly if it loads the bus down. Since XP's device manager sees the scanner, it could be just a bad communication board in the scanner. If the replacement scanner does the same thing, it would be interesting to test the USB bus voltage theory by connecting the scanner to another PC. Hope the new one works ok!!
