Q: Mavericks update, now scanner useless?!

Have you tried using the Image Capture app located in your Applications folder?

Connect the scanner to your Mac whether Wi-Fi or USB.

Launch Image Capture.

Click the very small black box bottom left side of the Image Capture window.

You'll see this pop up menu:   Connecting this (device) opens:

You can select a default app to scan (Image Capture) and select a folder from the Import To pop up menu on the right to save scanned files to.

Mac Basics: Using a scanner

It would help to mention which scanner manufacture model you have an which model.

Hi All, I called Canon this morning..

The Tech helped me Download the MP280 Navigator Software..

My MP280 works with both Scanner & Printer AOK............

Hope This Helps..............................

We are experiencing the same problem. After updating to OS X 10.9.2, our Canon IR Adv c5035 would no longer allow us to print or to scan and send documents to a designated file on our iMacs or MacBooks. Our Canon rep installed a new driver to fix the printing issue, but could not resolve the scan problem. We finally downloaded and installed SMBup and got 5 out of 13 computers working. Each One-Touch destination had to be tweaked individually to get it to work. But we finally hit a wall and apparently can't get any of the other computer addresses inputted properly. If anyone has any suggestions, we would certainly appreciate hearing from you. Thanks!
