Q: canon pixma mp530 won't scan in mavericks---driver needed?

You should contact Canon. According to http://support.apple.com/kb/HT3669, scanning isn't supported on this model.

Canon U.S.A say's that there are no new Drivers required for Mavericks.

Does Image Capture or Preview see the scanner..?

see > Mac Basics: Using a scanner and/or > How to Scan in OS X Using Image Capture

If you are having problem with Printing and Scanning, see > Reset the printing system

After I upgraded to Mavricks I could print just fine and even over my network, but I couldn't scan using either image capture or twain in Photoshop.

To get it working, I downloaded the driver and scanning software MP Navigator 2.2 from Canon for Mountain Lion (10.8). Whew, I really like this printer/scanner and was not looking forward to replacing it since everthing else has been working fine.

For some reason, MP Nav version 2.0.7 does work with my PIXMA 500 on Mavericks (10.9.1). I read somewhere that the latest version of MP Nav wouldn't work, so I uninstalled it and installed that older version, and all is well. Hope this helps.

I can print on Mavericks using the earlier driver (as others have mentioned).  However, the earlier MP Nav for scanning still did not work.  Since I already have VMWare Fusion running on my iMac, I downloaded the latest MP Nav for Windows, pass thru the Printer, and voila!  Scanning works fine.  I know it's not "mac-pure" but it was the only choice I had.  So, if you have Fusion (or another windows emulator) you may have similar success on scanning.

after reading these solutions i settled on downloading MPnav 2.2.4 and installing it.  I t works but will not relaunch one you have restarted you computer or quit the program.

So leave it running. and keep an installer handy for re installation if need be. 

Not very happy with whomever dropped the ball on this!!

after recently upgrading and finding this issue, i installed the lion drivers and version 2.2.5 of mp navigator now it works just like it used to in Snow Leopard.  Not sure if it was the driver update or the MP Navigator or both.  All I know is MP navigator 2.2.4 refused to stay open and a huge list of stuff popped up as to why.  Rest assured this did the trick!

same here.  Seems to only work thought the mp navigator, but thats ok.

I know that under mavericks the scanner did not work until i installed and older driver MP navigator 2.2.4

My be true for Mavericks, try it and let us all know.

When you download from the canon site put in the older OS 10.6  Now what about YosemitE???

I have Yousemite and the MP navigator 2.2.4 running. Still work the same way as with Mavericks. Same limitations, scanner is not visible in the Mac OS included tools
