Pages come out crooked and upside down on their own - not operator error! Why does this happen and can it be fixed?


I had the same problem scanning to PDFs with the CanoScan Toolbox until I went to the File Settings dialog, and unchecked the option "Detect the Orientation of Text Documents and Rotate images". Now it seems to work more predictably (no more scans that have been rotated for no apparent reason).

I bought the Canon Canoscan N1240u flatbed scanner. I downloaded the drivers and plugged in the cord that came with it but it doesn't do anything.


Just to be sure, did you install the driver in addition to downloading it? Full software or basic driver. The software must be installed before connecting the data cable. What OS are you using? (if you have Vista 64-bit, it is not compatible) If you didn't install the software, uninstall the OS driver and disconnect the data cable before attempting to install the Canon software. Otherwise see the notes for scanning with other software.

First are you trying to use the scanner buttons? These will only work if the full software is installed. For the buttons to work, you have to set up the scanner button destinations in the Canon software first. Also a monitoring program must be running for the button presses to work.

So try scanning from the computer first. If you still get an error, try a new data cable. If you are using a USB hub, try a direct connection. Make sure your USB ports work with a known working device. You can also check if the ports are disabled for security (in the Device Manager for Windows) or power savings (an advanced setting from the Screen Saver).

Once you have scanned successfully from the computer, go to the Settings section of the Toolbox to set the default destinations for the scan buttons.

If you only installed the basic driver, you can scan with Paint (XP or Vista), File > Import from Camera or Scanner > New Scan. Vista also has Windows Fax and Scan (New Scan) and Photo Gallery to acquire scans. I don't know the Mac software. Third-party software will also work if installed.

I hope this helps.

Cannon 4400F Scanner


I had the same problem with about 1 out of every 16 slides when I first got the scanner. The only way I found around it was to rearrange the slides and try again. I started scanning through the ScanGear software instead of Canon Toolbox, and haven't had that problem since. I've scanned about 6,000 slides and negatives so far.

You should download Toolbox as well. Toolbox gives you some scanning options and is helpful especially if you don't have any other software that allows you to scan.

Have uninstalled and reinstalled software for CanoScan LiDE60 and still coming up with 2 error messages - "cannot communicate with scanner" and " unable to open TWAIN source". How do I...


Are you scanning from Toolbox? Make sure the correct scanner is selected in the Settings section.

What OS is this? Try scanning from various applications.
Does the scanner react at all at any time?

Make sure you have installed ScanGear and not just Toolbox.
