Scanning fails I have a Canon Pixma MP150 printer&scanner in-one. For years there was no problem with it, until someone else installed the software on her own computer and used my Canon. Since than, my computer (macbook pro) doesnt recognize the scanner anymore; (i use MP Navigator 2.0 as software) its says 'scanning failed', and that there is no communication with the scanner. The strange thing is that it cant be the wire-connection, as i can still use it in printer-mode.. any solutions? many thanx

You have to configure the scanner utility in the printers software that is installed in your computer in order to use the scan button and send the command from the printer to the computer.

This is completely different then using the scan option by accessing it in your computer and sending the signal to scan from computer to printer.

Lets try using the computer to printer option first as its easier.

Go to "start" on the bottom left side of your computer screen

Slide up to programs and locate your Canon Pixma software and open it.

Choose the "Scan" option and hit "ok". Then just follow the prompts.

If its the first time using the scanner option, the software may ask you to confirm your choices for the default when choosing picture or documents. In general the software already has the default choices that are best for your machine in these areas. So just leave them alone and confirm them to continue on and use your scanner.

If this does not work for you or other issues come up while trying these instructions please clarify them and I will help you until able to scan right now.

There are a few possibilities. The simplest to check is try a new USB cable (shielded) and a direct connection (no USB hub). Scanners require bi-directional communication and thus will fail when the printer itself works.

Next try uninstalling the Canon software and remove all registry entries (for Windows). Use a program like Revo Uninstaller which searches the registry after the uninstall. Unplug the all-in-one from the computer. Reboot your computer (twice). Then download and install the latest driver/software from Canon: http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/pixma_mp_series/pixma_mp150?selectedName=DriversAndSoftware . Select your OS from the drop-down menu. When the software prompts you, reconnect the all-in-one to the computer.

The final issue is a USB issue. Try a different port and check for a hardware update related to the USB ports.

I hope this helps.

I had the EXACT same problem at first and I somehow solved it. All I did was restart the computer, unplug the cables and replugged them again. Started MP navigator and it worked!
Hope this will help.
