Just installed Mavericks, my Canon MP780 will print but not scan. What is the fix for this?

With early OSX, Apple had included the functionality of scanning from devices like Canon, HP etc. It included some generic drivers, you didn't need the specific driver from the device manufacturer. In Mavericks, they dropped the functionality of older devices, older than 8 or 10 years (guessing).

Fantastic. I installed the driver you suggested and my printer is working for print. Thank you so much. This is my first interaction with the Apple Support Community and I am very impressed. Hours on the phone with Apple Care had not come up with a solution.

Moving to a connected but different question, is there a way to now install my Canon Pixma MP780 through Parallels to my Windows XP installation so I can use the scanner from the virtual machine? I may buy Vuescan as recommended by Michele to scan with my IMAC, and may try the phone app as well, but I'd still like to be able to work with a program I am familiar with and I have documents I am runnning from programs in my virtual machine which I'd like to print.

Since I am new to the Apple Support Community, please let me know if I should ask this question as a new topic rather than adding the question to this thread. You all seem knowledgable and helpful so I thought I would try here first.

Thank you again for all of your help!

If you go to Canon's web page for the printer, it has some drop down menus with the available drivers etc. The page detects what your operating system is (at least when you log on using Safari) so if you go there using your Windows browser, is should tell you the available drivers compatible with that.

Or you may have to specify your OS and go from there.

I have made a great deal of progress but am not quite there yet. I spent hours on the phone with Parallels support yesterday and my virtual windows machine now works well with my printer. However, on the IMAC, after installing the printer driver 10.51.2.0, I can print from the paper tray but don't seem to have access to the utilities so I can't access the ability to use the cassette paper which is what I use for photos. When I go to Apple, Preferences, Printers and Fax, Canon printer, Options and Supplies, Utility, Paper Allocation, I get an error message 208 saying a file is required and to reinstall the printer driver. Is there a utility which works for you to get print previews, access to the cassette tray, etc?

On my PC, I had Paperport 14 professional and various photo software so it is hard for me to know which program had the utilities I used. I know the Paperport opens the printer up where I have the choices I want and I believe my Photoshop Elements 5 also had a printing utility I used. From what I have read, I can't set up additional photo utilities on my IMAC because they fight with IPhoto and I don't believe I can set up Paperport on the IMAC either.

Once again, thank you in advance for your help.

I went thru the same thing, and I'm 95% sure that there is no off-the-shelf driver or software that will give back the fuctionality that went missing in Mavericks. The companies like Canon or Apple draw a line at a certain age of device and drop them off the list of supported devices. They don't have the incentive to invest any effort into them, and in fact have the incentive to get you to buy something new.

Short of a hack, the only other suggestion I can give is to try running the driver from a slightly newer canon device like an 810 or 930 or something, and see if it will drive your device, because sometimes Canon and others will have thier software be compatible accross part of their platform. The other advice which is most likely to work is downdrade your OS to the last one before Mavericks

Elkabong and Cobbler:

I downloaded the printer driver 10.51.2.0 but Mavericks won't allow the install. I just get the following message:

“PrinterDriver_MP780_105102.pkg” can’t be opened because it is from an unidentified developer.

Has anybody seen that, and if so, is there a workaround for it? I'd rather not have to buy a new printer as this MP780 has been a great workhorse for quite a few years and was working fine before the OS update.

I appreciate the help.

Control-click and OS X will ask if you want to open it.

It's a Mavericks security "feature."

Awesome! I'm able to print now. Thank you, Greg!

But not scan

I had the same problem, but I figured how to fix it. You can enter the Canon webpage and download the driver for snow leopard OS, it will install and work with your Mavericks OS too.

Cheers!
