I initially wrote this post in July 2010. Today, I updated it with information regarding Photoshop CS6 and OSX 10.8.2 Mountain Lion.
I’ve always preferred doing my scanning from within Photoshop, since it offers a fuller range of control than most scanner software. It obviously interprets the RGB data extremely well. After turning on the scanner, launch Photoshop and scroll down the FILE menu to IMPORT, where you will see either the TWAIN option or the actual name of your scanner. That’s your ticket to scanning success.
In 2010, when I upgraded to from CS3 to CS5 and Snow Leopard, I was no longer able to scan from within Photoshop. At first, I thought Adobe had simply moved the menu item to another spot, but quickly realized that it simply wasn’t there any longer. I was able to use the scanner software easily enough, and the scan was moderately good quality. Yet, I was still dissatisfied, so I did some research and discovered a few interesting things, which solved the problem:
- Make sure you have the latest version of the scanner driver and software. The manufacturer will often provide downloadable files for free on their websites.
Without the current driver, curious things may happen: I was unable to see the preview in CS6 until I installed the newest driver. - On some discussion boards, people mentioned that CS5 cannot handle 64-bit scanning settings. To solve this, find the Photoshop CS5 file icon, Get Info (Command-I or FILE > GET INFO), and select “Open in 32-bit mode”. It’s important that you do this, because Adobe CS5 does not support 64-bit TWAIN scanners in either 64-bit or 32-bit Photoshop, and says “use at your own risk”. CS6 only runs in 64-bit mode: if your scanner driver can’t handle 64-bit mode, you may not be able to use TWAIN. My Canon PIXMA does work well in both modes, so I am fortunate.
- CS6 does not install several legacy (pre-CS4) plug-ins, extensions, and presets, including TWAIN. You can download the optional TWAIN plug-in at the Adobe website, for Windows or Mac OS. The CS6 plug-in supports 64-bit, while the CS5 plug-in supports 32-bit, on both Windows and Mac OS platforms, as well as 64-bit using Mac OS 10.6. For CS6, I placed the TWAIN.plugin file inside my Photoshop Plug-ins folder. For CS5, I placed the “32bit_only” folder (which contains TWAIN and other goodies) inside my Photoshop Plug-ins folder. Then I restarted Photoshop. Voila! Problem solved!
Adobe’s “HELP PAGE” on this subject is very useful, if you’d like more information.

Thanks Anne, I was JUST wondering the same thing about an hour ago. was going to look it up at some point but you saved me the time! Perfect!
You just saved me HOURS of frustration. THANKS.
How do you get PS to recognize your CanoScan scanner preferences? I was lucky enough to get my scanner recognized, but now it closes the Canon scanning dialogue box after each scan and disregards all of my other scanning preferences. What a nightmare! Please advise.
I think you have to choose just one set of preferences. If you want to scan from within Photoshop (after activating the TWAIN plug-in for CS5), then Photoshop probably overrides the CanoScan preferences. Whatever you’ve got set up in Photoshop will be the default.
Thanks so much, you just saved me lots of time!
You’re welcome! Glad to know the post helped you.
THANK YOU! Worked perfect. Gotta wonder sometimes why certain things “disappear”
Thank you so much!!!It worked perfectly!!But as you said earlier it works only in 32 bit mode..
Hello, I am operating in snow leopard 10.6.8. I too have a canon pixma. After I do the “get info”, there is no “open in 32 bit mode” as mentioned in your fix. I have had this problem when playing netflix in safari or chrome and was told to click the “open in 32 bit mode” where I did not find it for that either. Is there anything else you have learned regarding this problem? I just want to scan from photoshop again. Or is it possible to scan from Adobe Bridge? Thank you for any advice you can offer.
Thank you so much for this post. I was struggling and wondering why I could not get access via CS5 yet CS3 still allowed me to scan. This post clarified the issues and it is working fine! Appreciate you taking the time to post this.
@Z: Be sure you are using the Photoshop CS5 icon when you “Get Info”. The option to select “Open in 32-bit mode” does not exist in CS3, and I’m not sure if it exists in CS4.
You are my savior:)))
I am not the computer savvy lady and I actually could follow your instructions and IT WORKS!!!!
THANK YOU!!!!!
Merci
I’m happy to hear that it was helpful, thanks.
I’ve just purchased a new Mac for Xmas, and of course it came with Lion, and of course I’ve had to spend a small fortune upgrading lots of software, among which was my PS-CS2.
So thanks very much for this great advice. This was just one of many problems and you’ve saved me flipping my lid!

Hi Anne,
I just uppgraded to a mac with snowlion (OSX 10.8.2) and I use a Canon Pixma MP610 to scan. Of course my Photoshop CS6 is not able to scan anymore and I’ve tried to do just as you described but with no success. I downloaded the latest version of the TWAIN-plug in and I saved it in Ps/Plugins but I still can’t see my scanner in Ps/File/Import. What am I doing wrong, do you know?
I am grayteful for any help.
Hi Eva,
It sounds like you may not have the latest version of the scanner driver and software. Canon provides downloadable files for free on their websites. Without the current driver, curious things may happen: I was unable to see the preview in CS6 until I installed the newest driver.
If you’re on OS10.8.2, that is Mountain Lion, so be sure you select the driver and software that matches your Operating System.
Also, it’s a good idea to restart your computer after installing any new drivers or software.
Good luck! Hope it works, Anne
Hi Anne,
Thank’s for your answer! I downloaded the latest drivers today and also restarted the computer after but with no luck. I ended up scanning with the scanners own programme wich worked ok but was timeconsuming. I’ve read so much about others that have the same problem so I guess I have to do with the scanner programme for now. Thank’s again for your help!
Hi Eva, There are scanner drivers as well as print drivers, so make sure that you’ve downloaded the scanner driver. There are also some software upgrades available that you might as well download. Here’s the link to the Canon Pixma MP610 drivers and software for OS 10.8.2:

Some scanners are not compatible with TWAIN. I thought your Canon would be ok, though, so check the Canon site for troubleshooting details.
Good luck! Anne
Will do, Thank’s again Anne!
Bless you! I’ve been keeping an old version of photoshop on my computer just so I could scan from it. Now I can dump the sucker and use the new version. Thank you thank you thank you!
hello anne.
thank you for your post.
i’ve done all you say (downloaded twain 32 plug in, copied it to th plugins folder, reinstalled the scanner) but i still cannot scan from photoshop cs6. the scanner does work from its own toolbox. my os is windows 7 pro, 64 bit.
what else can i do?
Hi Gail,
Take a deep breath and read all of the info…
The CS6 plug-in supports 64-bit, while the CS5 plug-in supports 32-bit, on both Windows and Mac OS platforms, as well as 64-bit using Mac OS 10.6. For CS6, I placed the TWAIN.plugin file inside my Photoshop Plug-ins folder. For CS5, I placed the “32bit_only” folder (which contains TWAIN and other goodies) inside my Photoshop Plug-ins folder.
There are scanner drivers as well as print drivers, so make sure that you’ve downloaded the scanner driver. There are also some software upgrades available that you might as well download.
I’m more familiar with the Mac, so if you continue to have trouble, you might want to go to the Adobe website for more help.
Good luck!!
