I have a Canon MP 990 all-in-one and an iMac running snow leopard. I tried downloading an updated driver for OS 10.6, but am still unable to scan wirelessly. Keeps looking for a USB connection, which I don't have. Please help me sort this out. I have thousands of old photos and slides that I would like to archive. Thanks.

Run 'Software Update'
This will bring the OS up to 10.6.8
Keep running software update until the system is up to date.

Seems like it should work with your OS. For drivers/information, go here:

https://www.usa.canon.com/internet/portal/us/home/support/details/scanners/support-scanners-canoscan-series/canoscan-5000f#a72cde65-eaa8-479e-94a4-0e78ce832ebb_tab

scan with unother programm,photoshop or ACDsee

First try a new USB cable and swapping ports. Make sure other USB devices work.

Software and drivers are here: http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/pixma_mx_series/pixma_mx700#DriversAndSoftware (select OS from the drop-down menu then look for the notation of version 10.6). This site also has a firmware update for certain of these printers. Use the update with care, sometimes they will make a printer completely unusable.

I hope this helps.

Follow this link and select your OS from the drivers tab located on the page and you can download all the latest drivers for your printer including the scanner drivers.

Thank you and enjoy

I had the same problem. Upgraded from G5 PowerPC Tiger OS to iMac Snow Leopard. Have a Snapscan 1236U (ScanWise) and got the same error message ("cannot find the current ColorSync System Profile"). Downloaded trial version of VueScan (www.hamrick.com) , scanner worked, so purchased the VueScan Professional Edition ($79.99) (Standard Version is $39.99). My scanner is now working GREAT!

Did you install the software from the CD or did you download the driver? Are you using Snow Leopard?

If you have Snow Leopard and used the CD, you don't have the most recent drivers. Here is the link to the MP640 drivers. Remove the drivers currently on your imac and download and install from here, including the scanner driver and the MP Navigator (listed under Software).

The MX870 is compatible with Mac OS X, all versions. I think the CD that comes with the unit will have the Mac Snow Leopard drivers on it, but if not you will be able to download them here.

Make sure you have upraded to OS X 10.6.2 then download HP printer drivers for Mac OS X v 10.6.2 2.3 from Apple - Downloads - Firmware & Hardware - HP printer drivers for Mac OS X v 10.6.2 It worked for me.

Uninstall all your drivers (and delete the preferences) and download the Mac drivers from this link. The drivers that came with your printer were developed before Snow Leopard came out.
