Can only scan 2-3 slides at a time

Hewlett-packard Scanjet g4050 photo flat...
June 26, 2010 at 15:49:31
Specs: Windows 7
Dual Core Athlon running Win7Ult/64bit w 2.5 GB RAM.

When first installed, machine would scan 10-11 slides at a time but about every 40 slides or so the machine would scan one less slide at a time. Now after a few weeks of scanning the machine will only scan 2-3 slides at a time before getting this message: "There is not enough room in memory for the system to run the program. Reboot the computer."

Rebooting the computer did seem to help 3-4 times but not any more. The specs are that the scanner should be able to scan 16 slides at a time which would be nice.

I have had 5 long on-line tech support sessions with HP. We cleaned out Temp Files and Hard Set the Page File System. Still no joy. I have run the scanner from a clean boot start and shut off all other programs. Still no joy.

It seems to me some kind of memory is not being released as the program runs, but looking at all my files and operating performance, I can't find anything. All other programs work per normal while this error continues.

Sad as the scanner actually produces a good digital file. Scanning in full 6 colors at 1200 dpi. No, I don't want to scan at 300 dpi or buy a new machine as per HP support.

Any ideas?//Thanks.

How much free hard disk apace do you have? As each slide is
scanned it occupies space. Also temp files may be created.

Thanks Wizard--yes, the scanner does create a Temp file on the partition of the operating system (C-Drive) that has 2.2 GB free. On the initial scan, a raw file is created of about 500 MB and then that gets transcoded to a jpg file and stored in another temp file. I monitor those temp files and watch the free space on C-Drive change back and forth from 1.7 GB free space back to 2.2 GB free space. I did try to install the program on a different drive that had 1.5 TB free just the temp file wanted even more space than 1.5 GB but the Software will not install on anything but the C-Drive. I also monitor the CPU and RAM while the program works. CPU averages about 30% usage but does spike up to 100% usage but I don't get any error messages with those spikes. Ram is pretty steady at 40% usage. Error messages can be very misleading but it seems that "memory space" is available in my layman's understanding of the concept.

Any other ideas? HP Tech did suggest install it on another machine and see what happens but no one I know runs Win7/64 bit.

Also--I did uninstall the program and reinstall it. The program did however keep some default file settings so it did not completely unistall which was the point of the exercise. Result being--no change in the operation of the program.

I just rebooted the computer again. It is now scanning 3 slides at a time. when it lowers to two slides, I'm going to reboot into Safe Mode and see what happens then.

How much total free space is left on the partition and how large is the partition?

Is Windows also installed on this partition?

Are you keeping the jpg files created on the same partition?

How much total free space is left on the partition and how large is the partition? /// The partition is my C-Drive. 21.8 GB with 2.2 GB free when scanner starts and then it varies up and down to 1.7 GB. The page file on C-Drive is hard set to 2 GB. The free space reported on C-Drive never goes below 1.7 GB--just goes back and forth as the RAW file gets created, changed to jpg, and then deleted.

Is Windows also installed on this partition? /// Yes. The install program will not allow otherwise. Same with the Temp Files.

Are you keeping the jpg files created on the same partition? // No, those are transfered to another hard drive.

Its too bad that the HP software DESIGN is to keep all the jpg's until they are all batch processed and THEN they get transfered to the final storage destination. I have a feeling if the software would transfer the files one at a time as they are created that this issue might not come up--but such is not the case.

You don't have enough free space on that partition. You can't even run delfrag when you have less than 15% free.

Your problem is that the computer is having a hard time finding enough contigious space on the hard drive to write the temp files to.

You need to free up some space by moving things or expand the C partition, if possible.

If using a program to change partition sizes keep in mind there is a risk of something going wrong and losing everything.

Do you make backups or just have the one set? Backing up to DVDR is very cost effective.

Othehill--what you say "makes sense" in a general way which is why I tried to move the program to a larger drive. My memory is that the drive did have closer to 2.75 GB free space when it was processing more slides. I have moved and deleted everything I can but have not defragged the drive. That is an excellent idea.

I also did copy the C-Drive using Paragon to a new larger partition on the larger hard drive I have but the copy/clone does not work==another issue I'm working on.

I need more hard drives!!!! I will defrag and post back in a day or two about that solution. Thank You.

Other ideas?

Well, that was fun. Went to defrag my hard drive and found out it is done every Wednesday at 300AM. I have 0 fragmentation on all my hard drives.

On to find something to move/delete to free up more space. I've done that already, time to really get tough to see if it make a difference.

Undoubtedly you have filled up the drive more since you first started using the program.

What is the total capacity of your hard drive? If you have more than one partition you can custom install most any program to any available partition.

When the prompt comes up to install to C:\ bla, bla bla. You can highlight the path and change the C to something else.

Rarley is there a program that must be installed on the boot partition. I have the majority of my programs on other partitions or hard drives.

Othehill--I agree with what you say. HP is one program that will not allow installation anywhere except on C-drive. I have freed up 500MB on the C-Drive by uninstalling programs I can put back later. If I can scan one or two more photos, then I think YOU solved the problem and all I have to do is create a larger partition. Last time I did that, I lost the partition totally. Merging has worked in the past but there is no space. Still--next time I format a partition for Win7, its going to be 25 gigs. System is scanning the forth slide right now, just waiting for a memory error. If I don't get one, will remove even more programs and report back in 2-3 hours with how many slides I can then get.

Thanks Othehill==more helpful than HP Tech Support.

Yes, I'm now scanning slide no 6 so having free space on the C-Drive beyond the "free space" shown in system properties is the key.

Putting things together, I'm thinking the page file or "virtual memory" function may be interfering. In Win XP the page file was shown as a file in the C-Drive Root directory. No such file in Win7 so it must "occupy" the free space shown on the disk. So, its a nice combination of ambiguous/wrong status reporting information.

HP came "close" when they increased the virtual memory/page file and it makes sense except that all the temp files I can find stay within the free space reported which works out to about the same space as occupied by the page file?

Anyway, you can't fight what works AND ITS WORKING! I may not be able to get all the way to 16 slides without a larger partition, but I have the knowledge comfort level now.

Thanks Othehill. Here's a beer to YOU! Working on any "issues" yourself?

Yep--scanning slide 7 now.

Been using computers for almost 25 years and built all the rigs I currently have. That said, I have never owned a laptop. I bought one today and I find I can't type on it. So I am as we speak restoring it to factory state and returning it to Costco.

I am going on a vacation this week and thought it would be nice to have a computer so I don't go through withdrawal. I may net a netbook instead. If I can't type normally I may as well save half the cash.

Anyway, back to your issue.

I can't argue with you about the HP software installation but if you have other programs installed on C then just uninstall them and reinstall elsewhere. Or add a second drive. You didn't give any specs on your rig so I can't advise what to get. Browse for hardware purchases. That assumes you are in the US. They also have a Canadian site but don't ship elsewhere.

Glad I could help.

Yes you did help. I should have noticed the improvement when I moved/deleted some programs the first time, but maybe something else was going on at the same time.

One nice thing about the software is that it does allow multi-tasking without interfering that I can notice. I built my current rig about 3 years ago Dual core Athlon and actually this works "unless" I do transcoding at the same time with Super. Super tends to takeup 100% of the cpu enough of the time to stall other programs.

Would like to build my next system to maximize video encoding and multi-tasking so that looks like going Intel with their I7 line of processors.

I am on the computer 24/7 but last year went to Paris for 30 days. I was shocked I could switch over to reading paperbacks without a skip. Its all "input." A pleasure in both/either. More fun to check out the internet cafe's, but the libraries were interesting to! Enjoy your trip!!

I would check with HP tech support and ask if and why that software must be installed on the C partition.

BTW, I suggest you let windows handle the swap file. I doubt that manually increasing it helped. May actually have hurt.

I agree with you. But before that why question would come a few others like why don't they have a system to pass unanswered questions up the chain of command to someone who can? I do assume "someone" at HP actually knows what we have discovered. That info needs to get back down the chain to the system tech people reading their scripts. Thats why I never get upset with the script readers==but HP itself deserves some scorn.

I'm thinking setting the virtual memory to soemthing smaller might help--eg==push memory usage to the other hard drive that had 6 GB reserved for the page file. But then I was under the impression that as long as RAM was free, and most of it is almost all the time, that virtual memory was not needed?

Some things don't add up from this consumer's level of appreciation. Well, I only got to 10 slides. I freed up another 427 MB on C-Drive. Some of those "photo" programs I don't really use do take up a lot of space. Sample photo's I presume?

Windows was handling the swap file of one Gibabyte when HP tech was first called. I will ask them if it is possible to install on a different drive. I would well like it if all such programs were "free standing" for lots of reasons. I'd like to stop the HP Self Promotion ads on software I bought as well--but if I find a file and delete it, no doublt HP has designed the program to stop working?

Smile. Just another example of free ain't free?

Final Post--by clearing up another 427 MB of "free space" on my C-Drive I was able to scan another 4 slides. So, above some minimum free space of around 2 GB, looks like each slide requires about 108 MB of free space to accomplish the scanning process at 1200dpi, 6 color depth. I doubt I can remove another 200 MB to fully use the scanner, but I will look.

So, currently there is 3.89 GB of free space. If resetting my virtual memory and/or allowing windows to manage it affects this, I will post again.

Thanks to all who responded and especially to OtheHill for providing the answer. Cheers!

You are welcome.

Have you tried the built in partition re-sizer in Windows 7? You can access the service in Disk Management. First shrink the adjacent partition then expand the C partition. This may or may not work. I don't think there is much danger because you do keep the partitions defragged.

Remember to maintain your backups.

My "final" interesting experience: I changed the virtual memory from a hard set 2000 MB to "Let Windows Manage it." On reboot the free space on C Drive went from 3.89 GB down to 2.20 GB. I could find no new files created on the C-Drive--"space" was just lost. I could then only get 10 slides at a time.

SO THEN--I reset my virtual memory to a 500 MB hard set (both min and max were 500 MB). On reboot the C-Drive now shows 5.14 GB free space==and now I can scan 16 slides at a time.

It certainly appears that the HP software uses some kind of virtual memory and free space ((and Temp Files)) all on the C-Drive that affects scanning performance while giving error messages that don't help diagnose anything while reporting free space as adequate to do the job.

Following OtheHill's advice==if you want to get the full scanning capability of the HP G4050 scanner==get as much free space as you can and defrag it?

OtheHill==about a month ago I did try to expand the first partition into an empty second partition. I think the upshot was that resizing the first partition to a larger size did not work, but merging the two partitions did. Thankfully, right now, I don't have to worry about it===until maybe the small virtual memory file screws up some other function? I doubt that, but we shall see?

Now to find out why Win Seven won't allow renaming a file by removing the first blank space in the name==it sees it as the same name. Have to put an x in the space and then remove the x. This rename function has worked in windows for 20 years. Now it doesn't.

Similarly with Open Office spreadsheet. It sorts a column but thinks that B comes before A. How long has the ascending alphabet been "known" to the programers?

But MOST AGGRAVATING: the mouse pointer has always worked without thinking about it until Win 7. Now, its kinda erratic not holding onto highlighted material and refusing to highlight material etc. I've played with several mouse control settings and they do make a difference but these settings seems to revert back with other non-related system changes?

Things really ought to be easier/more stable than this?

PS--for all the HP owners out there, I will check this thread from time to time to see if there are questions. Hopefully, OtheHill might as well and machines that "should" work actually will be?
