Subject: Tech: Problem With Visioneer Scanner 8920 USB
From: Rabbi-Sol

I do quite a lot of work with Photoshop and I frequently have to scan slides and negatives as well as prints. My scanner is a Visioneer 8920 USB and it rus Scan Soft Pro software for its Photo functions.
When scanning photos or slides I will always use the highest resolution and largest size for the initial scan and then reduce it in photoshop to a workable image. My computer runs Windows XP (home) and has 1 Gig of ram and a 250 gig hard drive. For the past 5 years I have had no problem whatsoever with my photo scans. However starting yesterday my scanner software is not permitting me to scan at high resolution or large size. It is only allowing original size and low resolution. A red X appears at the bottom of the display that shows the size of the image and how much space is on the hard drive. Whe I try to scan, a message comes up saying that the image is too large to scan and shows 0 space left on my hard drive. When I go into My Computer it shows that I have 218 gigs of empty space left.
I called Tech Support at Visioneer and they told me that they no longer support this model scanner because it is over 5 years old and refuse to help me. Is anyone out there in Mudcat land familiar with this scanner and the Scan Soft Pro software that it runs ? I am not ready at this time to plunk down $200 for a new scanner.

We have one, though it is newer, a 9420USB. I'll ask Rog what he might know about it, Sol.

If you're scanning direct to Photoshop there may be a setting for your Temp space(s) that's gotten mismangled. I don't have Photoshop to look at, but I've had some "difficulties" with the rather bizarre settings I find in Photoshop Elements (ver 2 - a really old one).

WinXP should be able to use a fair fraction of the disk free space, and for most system temp spaces (there are several) shouldn't care a lot about whether it's all contiguous. Individual programs/processes can have their own unique Temp spaces, so using a lot for one process can eat up what's available for another one.

Older Win OS versions required each temp space to be in contiguous free space, so if the free space was badly fragmented the piece of it that could be assigned to a particular "Temp" folder could get really small, even with a lot of "total free space."

A thorough defrag of the hard drive might help.

Even if your WinXP can use fragmented Temp folders, if the scan program was built for an earlier OS it may restrict its own temp space ticket to the largest contiguous empty spot on the drive. It may or may not be able to relocate the temp folder by itself so you might need to force it to "re-establish" the space. If it uses an "address-assigned fixed" Temp space, any little bit of junk that gets written into the assigned Temp space for that program may make it look like there isn't any room left.

The suggestion would be (1) run Disk Cleanup to get rid of trash, (2) Defrag and (3) look for a way in the scan program to reassign the temp space/folder. If you don't find a setting in the scan program, (4) reassign Photoshop temp space(s) since some scanner programs may use the space reserved by the first "photo" program they find on the machine.

(Photoshop Elements, in my version, allows you to set a "secondary Temp" reservation that can be on another drive, but the usual setting is "session only" and that assignment has to be reset the next time you open the program. I haven't needed to look for a way to make a permanent such setting that will stick between sessions.)

I use an Epson Twain scanner program in Photoshop Elements that I got as an "update download" for my Epson flatbed scanner. I get the same "error" occasionally but only when I try to scan an 8"x14" (US legal size) page at 1200 dpi or more. (That would be a 17 megapixel (280 MB) single scan?) Scanning a bunch of individual pics stalls at about 115+ 0.5 - 1.5 MB objects. No error1, but when a scan "poops" I just save what I've got and start over.

1 When a scan stalls, trying to clear the scan-in-process in PSE closes the program and loses what you've got scanned but haven't saved. Turning the scanner off and back on closes the last scan so you can save the rest of what's up.

It appears that the problem with support for the Scansoft Pro scanner software may be because Scansoft no longer sells that program – or at least doesn't show it as a stand-alone item you can buy from them.

Visioneer has apparently switched to something called QuickScan Pro. The speculation would be that ScanSoft sold the control software to QuickScan (Visioneer?), since that sort of thing happens quite a lot.

Visioneer offers a couple of "Quick Start" and "Product Comparison" guides at the Downloads page. The quick start might tell you how to set Temp space, in terms similar enough to your program that you could make at least an ESWAG (Enhanced Scientific Wild-Assed Guess) at something you could do to help your situation.

The actual maker of the "replacement" program appears to be Captiva Software but their site doesn't appear to have a "Support" or "Downloads" button where ordinarily I'd be inclined to look for a User Guide that might be helpful. They may be one of those who only let you into support if you register a product – or maybe one of those who just don't offer support. They may sell only to resellers for "bundling" with scanners.

Your scanner may be one of those that scans everything to internal memory, and can't "stream" to an external program. Some of this kind have to complete a scan before offloading any of it. Is it possible that you've got some prior scans in scanner memory that don't leave room for another scan? Reset? Power Off and back on? Pull the memory chip(s)?

IF YOUR SCANNER uses insertable "memory" it's remotely possible that the memory card(s) have lost format. The scanner should have a "format" utility built in, if it works with "added memory" and if the chips have gone bad they need to be formatted by the machine that uses them.

The critical workings of the scanner control probably will be all included in the "driver" for the scanner. Your scanner could have some sort of "proprietary" output, but if your scanner can work with the "preferred standard" TWAIN mode, it's possible that substituting a driver (on your computer) for a similar scanner would give you a "workable" setup, although the features might be different. You should be able to try it, and if it doesn't work just delete the driver in Win Hardware Manager and reboot to let it go back to a default one.

If you can pick a "similar" machine, Epson (go to support for something that looks similar to your scanner) offers a .pdf User Manual for their TWAIN driver, for the scanner I use, and you should probably (maybe) be able to download the driver from a nearby page. T(hey didn't ask me for a product registration to let me into downloads.) With the TWAIN driver installed on my computer, my PSE File button shows Import|Epson Twain and can apparently (I haven't really tried it) import (streaming) from any scanner I connect and select, via the TWAIN "filter."

The ScanSoft Pro probably incorporated some other features like pdf conversion and maybe some image format/compression junk that you'd need another program for if you use a "bare bones scanner driver," but if you've got Photoshop it probably has most of that kind of stuff that you'd be really interested in.

Can't help but...

Pip had an older parallel Visioneer Scanner (Paperport?). I couldn't get it to work with Linux when I switched her over nor reliably with XP (I think 98 was the last supported Win although it did work on Win 2000).

Anyway I had an Epson Perfection 1250 that works on all our software. "Gave" that to Pip, thinking I could "borrow" it and that I'd get myself a new one if I found a need. So far, I have done so little scanning, I can't "justify" 2 scanners in the house.

Linux info but some may help if looking for similar drivers.

Sane project

I am glad to report that the problem was corrected. The temporary file that contains the photo scans (and acts like a scratch disc in XP), was accidentaly deleted. Now that it is restored the red X has disappeared and I can once again do high resolution scans. I now have my 217 gigs of free hard drive space bac. Thanks for everyone's help here that gave me the clues to look for the problem.
