Trop lent pour scanner un document sous XP PRO

[didiersee]

Bonjour,

Je possède un scanner HP scanjet 3400c et j’ai installé windows XP pro, le soft du scanner HP precisionscan LTX qui fonctionnait sous win 98 n’était plus opérationnel sous XP j’ai donc téléchargé la mise à jour pour XP et apparemment ça marche bien mais c’est très lent (j’ai 512Mo de ram).

Y a-t-il un paramètre à ajuster pour accélérer le processus sous XP PRO ?

Pcq sous win 98 c’était beaucoup plus rapide avec le même matériel.

 

-je possède également le programme Paint shop pro 7.04 de jasc software et la aussi il y a un problème, lorsque je choisis acquérir une image par twain le programme va écrire sur le disque dur très longtemps avant que l’image n’apparaisse dans la fenêtre de paint shop pro, y a-t-il un règage à faire dans win XP pro ou dans PSPro 7.04 pour résoudre ce problème et le quel ??

 

Merci d’avance pour votre aide.

Cordialement Didiersee

Désolé, c'est en anglais.

Invalid Disk Space Errors software update patch for the HP Scanjet 7400c series

 

 

 

 

SECURITY: Public

___________________________________________________

Windows generates "Not enough disk space" and "Not enough memory" errors and usually has nothing to do with the HP scanning software. Another symptom of is slow or halted scans.

 

"Out of memory" errors can occur when there are not enough system resources to perform the task. These errors can occur regardless of how much Random Access Memory (RAM) installed on the computer. Adding more RAM may not fix a low system resources problem. Please try some of the other solution listed in this document.

 

Before beginning

Print this document using the printable version link on this page. The document will not be available once the computer system is restarted or after performing some of the solution.

 

Resolving RAM and memory leakage

To regain the leaked memory Restart the computer. Then retry the scan.

 

Summary

Random Access Memory (RAM) is the memory used to run applications. As more applications open, less RAM is available for use.

 

Memory leakage occurs when an application is closed, but does not return the entire amount of RAM it was allocated by the operating system.

 

Memory leakage decreases the amount of RAM available to run other applications, resulting in memory or disk space errors and slow or incorrect scans.

 

Verifying that minimum system requirements

Verify that the computer meets or exceeds the minimum amount of RAM required for the HP Scanjet scanner.

 

The minimum system RAM information is on the box or found online in the product specifications.

 

Checking the amount of space available on the hard disk drive

Open My Computer:  

In Windows 95, 98, Me, and 2000, Double-click My Computer.  

In Microsoft® Windows XP, click Start, and then click My Computer.  

Right-click the hard drive icon and select Properties to view the amount of hard disk space used and available. If there is more than one hard disk drive or drive partition, repeat this process for each physical drive letter listed. Do not do this for any listed network drives.

Checking the amount of system resources available

Restart the computer and check the resources again. Usually more resources are available after restarting the computer. This is because of a condition called memory leakage. See the memory leakage section below for more information. Follow the steps listed below to check the system resources:

 

Windows 95, 98, and Me

Right-click My Computer, and then click Properties.  

Click the Performance tab. The amount of memory free is expressed as a percentage.

Windows NT 4.0, 2000, and XP

Press and hold the CTRL and ALT keys on the computer keyboard, and then press the DEL key once to bring up the Windows Security Screen.  

Click Task Manager.  

Click the Performance tab. The amount of memory being used will be displayed as well as a graph of memory usage over time.

Cleaning up the computer system

Windows 98, Me, 2000, and XP users should run Disk Cleanup to remove temporary files

Click Start, click Programs, click Accessories, click System Tools, and then select Disk Cleanup.  

The tool will request which drive it is to cleanup, even if only one hard disk drive is installed. Select the hard disk drive(s), and then click OK.  

Disk Cleanup analyzes the hard drive and presents a report (Figure 2). Make sure that Temporary Internet Files, Downloaded Program Files, Recycle Bin, and Temporary Files are selected. Then click OK to perform the cleanup operation.

Figure 2: The Disk Cleanup report

 

 

 

Windows NT 4.0 and 95 users should manually delete temporary Internet files and other temporary files

These two operating systems do not have the Disk Cleanup utility so the cleanup must be performed from within the Web browser. From within Microsoft Internet Explorer, the following steps accomplish this:

 

Open Internet Explorer, click the Tools menu and then click Internet Options.  

In the Temporary Internet files section, select Delete Files. Close Internet Explorer when finished.  

Click Start, click Find, and then click Files or Folders.  

Named box type: *.TMP  

Make sure that the hard disk drive that contains Windows is selected in the Look In field and that Include sub folders is selected. Then, select Find Now.  

Delete any file that does not have a tilde (~) in front of it. Close the Find window when finished.

Delete old or unused software

It is a good idea to run Scan disk and Defrag after removing large applications so that the hard disk drive can be reorganized.

 

Click Start, click Settings, click Control Panel, and then click Add/Remove Programs to access the Add/Remove Software wizard.  

Select an application, and then click Add/Remove to uninstall the application.

Empting the Recycle Bin

From the Windows desktop, double-click Recycle Bin.  

Restore any mistakenly deleted items by highlighting each file, clicking File, and clicking Restore.  

Click File, and then click Empty Recycle Bin. Windows will remove the contents of the Recycle Bin from the hard disk (C: is most common). Select Yes to confirm.  

Close the Recycle Bin.

Running Disk Defragmenter and Scan Disk

Run Scan Disk and Defrag (Defrag may not be available in Windows NT 4.0) on the hard drive.

 

Click Start, Programs Accessories, System Tools, and then click Disk Defragmenter.  

Select the hard drive to be defragmented, and then click OK.

Summary

A memory error may also occur if other error conditions are present, such as a missing file error. The memory error will go away once the other error condition is corrected. If this is the case, a missing file error message will appear after the out of memory error. The missing file must be located or reinstalled.

 

Disabling background tasks to free up system resources

Many applications load tasks that run in the background to either place toolbars or icons on the Windows desktop. Many of these are not needed nor desired and can be shut down. Refer to HP Support document HP Scanjet - How to Increase System Resources Without Adding RAM for more information

 

Use Universal Serial Bus (USB) instead of parallel (only applicable to scanners that can be connected by parallel or USB)

If the scanner is connected using a parallel cable but is capable of being connected using a USB cable, complete the following steps:

 

Uninstall the HP scanning software.  

Disconnect the parallel cable connecting the unit to the computer and unplug the power cord to the scanner.  

Reinstall the HP Scanjet scanning software, selecting USB when prompted.  

Connect the scanner to the computer using a USB cable.  

Reinsert the power plug into the scanner.  

Try scanning again.

Virtual memory settings

Scanning tasks use virtual memory to store information. Virtual memory is unused space on the computer hard drive.

 

Summary

A computer should have at least 100 - 200 MB (depending on the version of Windows) of free disk space for Windows to use as virtual memory. Be aware that other Windows components also use or reserve portions of hard disk space, such as the print spooler and recycle bin.

 

In Windows NT-based operating systems (Windows NT 4.0, 2000, and XP) the amount of virtual memory should be over 200 MB. If the task requires more virtual memory than what is available, an error will occur. The size of the virtual memory available can be modified in NT based Windows operating systems. Complete the steps under the appropriate operating system to check and set the virtual memory settings.

 

Windows XP

Click Start, right-click My Computer, and then click Properties.  

Click the Advanced tab. In the Performance section, click Settings.  

Click the Advanced tab. In the Virtual memory section, click Change.  

The hard disk drive that is used for virtual memory will usually be the same disk drive that Windows is installed on. Both the Initial and Maximum settings should be less than the reported Space available on the hard disk drive. The Initial size setting for the virtual memory settings should be approximately 200 MB in size but should be higher than or equal to the recommended paging file size as indicated in the lower section of the screen.

 

Once the initial size is set, Windows will reserve this amount of space on the hard disk drive for virtual memory and it will not be available to save information on.

 

The maximum amount allowable can be anything above the Initial size setting, but it is recommended that it be at least twice the Initial size setting as shown in Figure 1.

Click Set, and then click OK to save any changes.

Windows 2000

Right-click My Computer, and then click Properties.  

Click the Advanced tab, and then click Performance Options.  

In the Virtual Memory section, click Change.  

The hard disk drive that is used for virtual memory will usually be the same disk drive that Windows is installed on. Both the Initial and Maximum settings should be less than the reported Space available on the hard disk drive. The Initial size for the virtual memory settings should be about 200 MB in size and should be higher than or equal to the recommended paging file size as indicated in the middle section of the screen.

 

Once the initial size is set, Windows will reserve this amount of space on the hard disk drive for virtual memory and it will not be available to save information on.

 

The maximum amount allowable can be anything above the Initial size setting, but it is recommended that it be at least twice the Initial size setting.  

Click Set, and then click OK to save any changes.

Windows NT 4.0

Right-click My Computer, and then click Properties.  

Click the Performance tab, and then click Performance Options.  

In the Virtual Memory section, click Change.  

The hard disk drive that is used for virtual memory will usually be the same disk drive that Windows is installed on. Both the Initial and Maximum settings should be less than the reported Space available on the hard disk drive. The Initial size for the virtual memory settings should be about 150 MB in size and should be higher than or equal to the recommended paging file size as indicated in the middle section of the screen.

 

Once the initial size is set, Windows will reserve this amount of space on the hard disk drive for virtual memory and it will not be available to save information on.

 

The maximum amount allowable can be anything above the Initial size setting, but it is recommended that it be at least 200 MB or twice the Initial size setting.  

Click Set, and then click OK to save any changes.

Check the image size of the scanned item

Image size information is shown in the HP Scanjet scanning software. If the size of the file is nearly equal to or larger than the amount of hard disk space free, the task will fail.

 

Decrease the image resolution to 72 dpi and try scanning again. If the scan works correctly, the previous resolution setting was too high and created too large of a file. Follow the instructions in the "Virtual memory settings" section above.  

Most computers cannot handle files over 200 MB in size because they lack the RAM, virtual memory size, free hard disk space, or any combination of these. Scanning images at extremely high resolutions or color depth creates files that are extremely large. In many cases, the files are too large for the computer to handle.  

In most cases there is no need to scan or work with images at high resolutions. There is no reason to scan at a higher resolution than the destination of the scan is capable of displaying. For example, the average computer monitor displays images at approximately 72 dpi. Scanning an image at a resolution higher than 72 dpi is a waste of system resources and hard disk space if the image is to be viewed only on a computer monitor.

Invalid Disk Space Errors software update patch for the HP Scanjet 7400c series

When attempting to save an extremely high resolution scan using an HP Scanjet 7400c/7450c/7490c series scanner and HP Precisionscan Pro 3.0x, an invalid "Not Enough Disk Space" error will occur even when there is adequate free hard drive space to save the file.
