Scanner not working

Make sure you have installed the scanner drivers bcos sometimes it only installs printer drivers. I suggest you install the scanner drivers again. Make sure the scanner is turned in first b4 computer.

Does the same error occur if you launch a scan from the computer? What OS do you have? Vista only has a basic driver available and does not support the scanner buttons. (You can launch the scans from a number of options: third-party software, Windows Fax and Scan (new scan), Microsoft Paint (File > Import from Scanner or Camera > New Scan) and Windows Photo Gallery.)

If the error occurs when you launch the scan from the computer, try a new data cable and different USB ports. Try a direct USB connection if you use a hub. Then check your USB ports and the drivers for the USB. (For Windows, look in the Device Manager. Start > Control Panel > System > Device Manager (exact directions will depend on the OS).

The HP Photo and Imaging software requires you to set the default scan destinations in the software before you can use the buttons on the scanner (for those OS/driver versions that support the feature). Always open the software and scan from the computer to see what the defaults will be. Each version of HP's imaging software set up these buttons differently; the help option is useful. Try Scan > Scan settings to find where to set the color and black & white destinations.

I hope this helps. If you add a comment with your OS and whether the computer can launch a scan, I'll provide additional help if I can.

(who inherited a scanner when a USB hub failure aggravated the original user into buying a new scanner thinking it was a scanner problem.)

Do you have the full software installed or just the basic driver from Canon? What OS are you using? http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/pixma_mp_series/pixma_mp240#DriversAndSoftware has the software and drivers. If you installed the OS driver, you should uninstall that, disconnect the data cable and then install the driver from Canon. The generic OS driver usually only runs the printer.

Place the document face down on the scanner glass or face up if you have an ADF. Check that the all-in-one and the computer have good bi-directional communication. (Direct USB connection (if you are using that), replace cables if the printer works but not the scanner and the Canon software is installed.)

If you are using the Canon software, you need to set up the destinations for the buttons and have the monitoring software running. Thus start scanning from the computer at first. Launch MP Navigator and then click on the type of document you want to scan. Find the resolution and contrast that works for you. Use these in setting the button defaults (see the manual from Canon). Then click Scan.

Alternately, with Windows XP, Vista and Win7, you can scan with software that came with the OS. Paint is available on all of these OS versions (File > Import from camera scanner > from scanner). Vista includes PhotoGallery which works like Paint (this can be downloaded for XP and Win7). Vista and Win7 also can scan with Windows Fax and Scan (New Scan).

When you have the MP Navigator properly set up, you will be able to launch a scan from the printer. Press the Scan button and the software will launch.

I hope this helps.

It depends a bit on the software you have installed (OS, etc). If you installed the full-featured software before connecting the all-in-one to your computer, you can scan immediately from the computer. For Windows, open the HP Solution Center (by double-clicking on the icon or Start > All Programs > HP folder > HP Solution Center). Put your document to be scanned face down on the scanner glass and close the lid (ADF pages go face up, top edge first). Click the tab in the Solution Center for your HP product (if you have more than one) and click Scan Picture or Scan Document as appropriate. Set the scanner settings in the pop-up window if needed. Click Scan to start the scan. To use the buttons on the scanner, you need to set the destinations for the buttons in the HP Solution Center (Scan to destination for example) and have the HP monitor running on your computer (this listens to the buttons).

Scanners work with bi-directional communication so USB hubs, print servers or bad cables can result in the printer functions working but not the scanner.

If you install the generic OS driver (by connecting the all in one to the computer before installing the software), the printer will work but the scanner will functions will be limited (the scanner buttons will not work but other functions will depend on the OS). Windows XP can acquire scans in Paint (File > From Camera or Scanner). Windows Vista and Win7 add Windows Fax and Scan which will also acquire scans (not in all versions of Vista). Vista also can acquire scans with Windows Photo Gallery.

The printer works similarly with the Mac OS but hte names may be different.

I hope this helps.

You would need to download the software for your printer again and then install it on your computer. You can download it from here. Once it is installed, look for the scanner icon or HP Director which would have scanner icon.

Having exactly the same problem with an Epson SX515W. Did you solve it?

DS Dual 4 even works with SnowLeopard on a CoreDuo MBP. But it doesn not support Autofocus when used under USB2. You have to use a USB1.1 Port, if you want to use autofocus function. Every time the software crashes, because you tried e.g. to use autofocus with USB2, you will have to close the application, go to the folder User/Library/Preferences/DS Dual4/... and look whether there is a file name something like "MFSlib...." and pull it to the trash bin. You can start the application again. PS.: Your keyboard USB port is a USB 1.1 port!

You need to set up the software on the iMac. The reason it gives you that error message is because it can't communicate with the computer and imaging software as the computer doesn't see the scanner and can't communicate with the printer's control interface. The iMac may see the printer and be able to print without any additional software because the driver package for the printer portion may already be installed with the OS X HP printer driver support. You didn't mention whether or not you could print from OS X. I am assuming you can. Faxing and copying from the unit doesn't use the computer at all and doesn't need to communicate with it. Scanning and printing do. If you can't print either then none of the driver or support software is installed and you have to set it up. You can get the instructions for setting the printer up in OS X 10.5 from HP. Just click here and it will take you to the page with the instructions.

Best wishes and cheers

I cannot scan from my Pixma mx700. I have an imac, reinstalled software, downloaded new drivers...HELP

i was told that the printer needs to be directly connected to the imac (not airport) for the scanner to work.
i have the same issue w/ the airport extreme.
