Are any scanners working with Mavericks? Am I the only person who believes that scanning has become an essential service of any current OS?

I'd been happily scanning wirelessly using Image Capture and my Canon MX860. After upgrading to Mavericks today, I can print but no longer scan. It seems I've installed every driver and utility from Canon's website. Even Canon's "MP Navigator EX" app is refusing to scan, giving me the following error:

**

The scanner is not available while in use by another application or user. Click [Scanner Selection] if you want to select another scanner. Scanner driver will be closed.

203.0.0

Anyone with a Canon have any luck with Canon's own app?

I agree that access to a scanner is essential in many households and businesses. It certainly is in ours. It did not occur to me that our Epson Perfection V330 Photo would not work as usual after installing Mavericks.

The advice from Epson support was to use Image Capture until the new drivers were released. The scanner worked with Image Capture but was a lot less convenient to use so I installed the new Epson driver as soon as it appeared. The result is that our scanner no longer works at all. When connected and turned on, there is a red flashing light that stops after about 30 secs. Image Capture no longer finds the scanner; the Epson driver doesn't work at all. I have spent days on this already. Yesterday, I downloaded VueScan but that doesn't work, either. It appears to me that "something" in the new driver has terminally damaged the scanner. The scanner itself is 18 months old, just outside the 15 month extended warranty. Epson has been extremely unhelpful so far. One would think that Epson would take an interest in something that affects so many of its customers, but no.

My first thought was to buy another brand but it appears that Mavericks has wreaked havoc on most brands of scanner and that successful installation of the new drivers appears unreliable. I hope that Apple will put some effort into finding a solution.

My HP printer-scanner (officejet pro 8600) works fine with the new scanner software download from HP.

I find it hard to blame Apple for all of this. The beta of Mavericks was out for almost six months. Plenty of time for all the printer and scanner manufacturers to get their acts together and get their software updated, but they didn't. Shows you what they think of you, their customer.

The printer and scanner "utilities" that come with the printers/scanners are notoriously bad, BTW. My suspicion is that the manufacturers still don't value the Mac segment of their customer base very much. So they don't assign their best and brightest software engineers to their Mac department. Not their Rhodes schlolars. Kind of like with Al Qaeda: they don't assign the brightest guys to be the suicide bombers.

What I have found that works well is the following:

1. uninstall all printer manufacturer apps and "utilities" for printing and scanning
2. go to System Preferences > Printers & Scanners > Print
3. control-click on your printer in the column on the left
4. select "Reset Printing System..." and "reset" in the dialog that follows
5. do a factory reset on your printer/scanner. You'll have to consult the manual for how.
6. if you connect via wifi to your printer/scanner
   1. power down everything: modem, router, computer, and printer/scanner
   2. power up each item in turn in the same order: modem, router, computer, and printer/scanner. Let each power up completely before moving on to the next
   3. enter your wifi password in your printer/scanner so it can connect to the network, if you connect via wifi
7. go back to printers & scanners and it should see your printer and download a driver for it from Apple
8. open Image Capture (it's in Applications), and it should see the scanner and download a driver.
9. See if that works.

Thank you for your detailed suggestions, Arthur. I cannot find a way to do a factory reset on my Epson Perfection V330 Photo flatbed scanner, despite checking the user manual, googling and searching other forums. If anyone know how to do this, I would love to give it a try. I will try asking Epson Support after they get back to work after New Year.

Maybe there is no factory reset for it. There is for my HP, and it seemed to be necessary to get it working with Mavericks.

I have an HP Photosmart D110. I want to scan with that. The image capture is much more limiting and doesn't allow for multiple documents into one scan file. This is ridiculous. Do I need to go back to PC world to get that functionality?

My Canoscan 8400F won't work under Mavericks (it took me a lot of trouble to get it work under Lion) and Canon have told me there will NOT be a driver for Mavericks. Since I paid over $300 for this scanner about 7 years ago (and, judging from the research I've done, I'd need to spend about $400 now for a new, equivalent scanner) I am not amused. I wasn't able to get Vuescan to work under Lion, and when I upgraded to Mavericks it was the same, but I've now managed to get it to work. I'm not sure what I did, but it must have been something to do with my frantic search for a driver (I installed just about everything I found, without luck—of coruse) which ended in my contacting Canon.

I'm not blaming Apple; they didn't make the scanner. I blame Canon. It's enough to make one never want to buy another Canon product.
