Question

Why doesn't Photoshop see my scanner or the plugin? (Mac OS)

Just loaded CS4 on Mac 10.5.7. I downloaded and installed the latest OSX Epson 1240U scanner software, and also copied the Twain plugin from the Adobe Goodies CD to the Photoshop > Plugins > Import/Export folder. Rebooted the computer, power off and unplugged my USB scanner, fired it back up, restarted Photoshop, etc. The scanner software works fine in stand-alone mode.

But Photoshop doesn't see my scanner at all. In fact, the TWAIN plugin doesn't even show up in the plugins folder list.

Whaz goin' on? How do I fix this?

Thanks, Lou

All these explanations are undoubtly valid, but beg the original question. If you still have CS3 on your computer and want to try scanning from CS5, open each to the Plug-ins/Import-Export folder. CS3 should have the file Twain32.8BA, or something similar. Copy that file from CS3 to CS5, open CS5 and voila, your scanning should be enabled. Mine works so far. I suppose if it does start to crash all I'd have to do is delete said file. I'm assuming the same procedure would work in CS4. As with most computer advice, proceed at your own risk.

Not only are you replying to a six-month-old thread, but you seem not to realize this is the Adobe Photoshop Macintosh forum, WDH77. There are no files with anything resembling that Windowish extension on the Mac.

See....and after all that; PHOTOSHP IS RELATED TO SCANNING IF YOU WORK IN THIS AREA: If you don't then you don't know what pleasing ///and winning the client is all about.

PHOTOSHP IS RELATED TO SCANNING...

NO! PS is about retouching, color-correcting, compositing, converting, etc...

How you get the image into your computer as a digital file is irrelevant to Photoshop...

Yeah, back in the day of SCSI scanners, it was a great convenience to scan into PS, do some preliminary adjustments, and save the file, to be worked on later...

You don't need to scan into PS to "Please/Win" the client. They couldn't care less about your workflow. You agree that the end result is what matters, right?

Using the TWAIN plugin to bring an image into PS, or scanning outside of PS, then bringing it in for final adjustment, makes no difference...

Except, as Chris points out, you're less apt to lose a lot of work if you do it OUTSIDE of PS.

Oh yes..yes it is. Scanning is Directly /related to photoshop. don't listen to those w'eird thoughts in your heads..

if you are ANY sort of Artist, Designer, Technician...Photographer, Digital Imager..You would know Photoshop is related to Scanning .

I would know. I've spent 29 years in the Retouching/Digital Imaging/ Photography fields of work. Oh yes, Now, I ask you then;

I f you got a second-rate Scan of something; do you mean to tell me it doesn't matter what comes of it in PHOTOSHOP!?

OF COURSE IT DOES! I want the best possible scan;; the best image possible for the best outcome for the Client.

Then none of you are professionals if you feel that way.

BushyPenny,

At first, I didn't like it either, since I was accustomed to scanning directly into Photoshop, but apparently TWAIN can cause problems with Photoshop depending on the TWAIN driver. It's no big deal once you get used to it. I find it no problem to scan to disk and open the resulting TIFF in Photoshop—it's a minor adjustment in my workflow. I'm the one who started this old thread. If it improves the reliability and stability of PS, no problem here.

HI folks: I am but ANOTHER
User of Photoshop CS4....Just installed it on my Mac Pro;

I have an EPSON GT20000 Scanner; IT USED TO WORK THROUGH PHOTOSHOP
CS2...Now in CS4 it DOES NOT WORK!!!! They removed the active "PLUG_IN you need;

I've tried..like 25 times- to OPEN the plug-in...from GOODIES disc..did Everything under the sun

it does not and WILL NOT WORK through Photoshop CS4. it is useless. I can't believe they

did=away with Scanning through Photoshop now; I used to go "FILE-IMPORT> Twain,

or GT20000 it was SO SO convenient. I'v tried calling ADOBE 800PHone no# and I was on hold

for 1 hour 20 minutes and just gave up. NOTHING will work and I hate this so much;

Photoshop is DIRECTLY related to scanning and for them to messs this up is tragic.

Sorry-in NYC.

Photoshop is not directly related to scanning. Photoshop is related to images, and scanning is just one way of getting images into the computer.

Your scanner driver software is much more closely related to scanning.

You can scan using the software that came with your scanner by itself, or you can install the optional TWAIN plugin and hope that your scanner driver doesn't crash Photoshop.

... And that's all there is to say about THAT!

Lou,

First of all, you install the TWAIN plug-in at your own risk in CS4. It was intentionally left out of the default CS4 installation for a good reason, namely that many scanner drivers will give you grief.

In addition, it's more efficient to scan outside of Photoshop instead of tying up an expensive application to call upon the scanner's software anyway.

Beyond that, there should be no problem if you installed the scanner driver correctly. Exactly how did you do it?

Another thing is to respect the default Photoshop installation meticulously. Do not move the Photoshop icon or the Photoshop folder, do not create subfolders for them, etc.

Also, that's an ANCIENT scanner (I know, I have one right here :-).

Chris makes a very good point. The driver for that scanner was probably never updated for Universal Binary. If that's the case, there's no way that it will run from within Photoshop on your brand new Mac-Intel machine.

Chris/Ramon:

Thanks for your answers. Like I said, the scanner software seems to work fine in stand-alone mode. I'm just used to importing scanned images directly from within PS.

To install the Twain plugin, I just dragged it from the Adobe Goodies DVD directly to the Photoshop > Plugins > Import Export folder (which is what it said to do in the Adobe Readme file). Just seemed strange to me that it wouldn't show up in the Photoshop Plugin list at all, just like it isn't there. I restarted PS and it still doesn't show up.

Hey, if it won't work from within Photoshop, it won't work. Just seems odd that PS doesn't even SEE the plugin.

Chris, would you recommend NOT using it from within Photoshop?

Thanks,

Lou

Because CS4 moved the TWAIN plugin to optional plugins -- too many buggy scanner drivers were causing Photoshop to crash, and Adobe has no control over those buggy scanner drivers.
