scanner does not scan

Using HP scanjet 3300c with Windows 98 version 2 and a USB port I press the scan button on the scanner, The LT software opens and a window opens that says starting new scan. The light in the scanner comes on but it does not scan. When I click ctrl,alt,delete, it says program not responding.When I first installed the scanner it made a few scans before it failed so I belive the hardware and connections are OK.

ISSUE: The HP ScanJet scanner fails to work when installed, or quits working after it has previously functioned. The scanner may also appear as an unknown device under the USB category in Windows Device Manager.

SOLUTION 1: Problems with specific makes and models of PCs:

IBM 300GL or IBM 300PL computers
USB ports on the 300GL/PL may experience a communication problem known as "jittering." Contact IBM to see about replacing the motherboard.

E-Machine Model 336e
Customers who have this computer have resolved their issue by replacing the E-Machine Model 336e with Model 336i. The root cause of this problem is currently unknown.

Toshiba laptops
Owners of Toshiba Techra, Infinia, and Satellite Pro laptops may experience problems connecting a USB scanner. If the normal troubleshooting steps do not resolve the problem, running the scanner on the USB port may not be possible. If the scanner has another interface option, like SCSI or Parallel, the scanner may work just fine by using that interface.

Quantex computer
Go into CMOS Setup (BIOS), Advanced Chipset, and enable the USB port and the Passive Release. You may need to contact your PC vendor or manufacturer for assistance in making these changes.

SOLUTION 2: Uninstall and reinstall the scanning software. Disconnect the scanner USB interface cable and power. Reboot the PC, connect the power back to the scanner, and then reconnect the USB cable.

SOLUTION 3: If the scanner you have is an HP ScanJet 4100C, 5200C, 6200C or 6250C family scanner, you may need to download the USB patch. Click here, to down load the patch: sj435en.exe. In the Search window type in the file name: sj435en.exe, then press the Search button.

SOLUTION 4: If the scanner you have is an HP ScanJet 6200 or 6250C or HP ScanJet 5200C, switch the scanner lamp Operation Mode from Economy/Energy Star-compliant to Fast Scan.

Open the Control Panel, open Scanners and Cameras, select Properties, and then select Lamp. Change the setting from Energy Save to Faster Scan, then select OK. Restart the PC; power cycle the scanner.

SOLUTION 5: If the scanner is an HP ScanJet 6200 or 6250C or HP ScanJet 4100C, verify that the file HPSJCLAS.DLL exists on the system and is 20 KB in size. If the file cannot be found, or it is larger or smaller than 20 KB, then copy the file from the Drivers directory of the HP CD-ROM to the C:\Windows\System directory on the PC.

SOLUTION 6: Right-click the My Computer icon and select Properties. Click the Device Manager tab, scroll down to Imaging Device, click the plus sign (+), and select the scanner listed. Remove the scanner with the remove tab at the bottom. Shut down the PC, unplug both the USB cable and the power cable from the scanner. With the PC off and the USB cable still disconnected, plug the scanner power cable in and let it completely power cycle before unplugging it. Power cycle the scanner at least five times this way before hooking up both cables and restarting the PC. New hardware should be found on the reboot.

SOLUTION 7: If the scanner is an HP ScanJet 5200C or HP ScanJet 4200C scanner, verify that the file HPSJVSET.DLL exists on the system and is 90.5 KB (for the 5200C) or 92.5 KB (for the 4200C). If the file cannot be found, or is the wrong size, copy the file from the HP CD-ROM to the C:\Windows\System directory on the PC.

SOLUTION 8: In Windows 98, check the Automatic Skip Driver Agent to find out if any drivers (in this case, USB drivers) are being skipped by Windows.

From the Windows desktop, choose Start, Programs, Accessories, System Tools, and then System Information.
Select Tools and then Automatic Skip Driver Agent. If any drivers are listed as skipped, check the box next to the driver, and then reboot the computer.
Check Automatic Skip Driver Agent again. If the USB drivers are still being skipped, contact the USB manufacturer for specific USB troubleshooting.


NOTE: We have seen some instances in the past where having the USB Host Controller share an IRQ with another device has caused the scanner to not be recognized by the computer. This has been especially true when sharing IRQ's with ISA cards and network interface cards. Although it may or may not be a solution, we do recommend that customers investigate the possibility of having the USB Host Controller be on an IRQ alone, if only for testing purposes. This would need to be done with the manufacturer of the computer.


this is another possible solution

ISSUE: When attempting to open the scanning software, the following error occurs; "Sorry, could not access your scanner; your scanner is currently being accessed by another application. Please wait for that other application to finish and try your scanner again." The error "Scanner in use by unknown application " may also appear. The HP PrecisionScan LT software may also hang, instead of giving the above error message. The scanner will appear to be correctly installed in both the Device Manager and in the Scanners and Cameras icon in the Control Panel.

SOLUTION 1: What usually causes this issue is when STIMON is missing from the task list. To check for this problem, press CTRL+ALT+DEL and look through the Close Program box for the above listings, if it is not present that is the problem.

First, check to see if STIMON has been removed deliberately.
Select Start, Run, type MSCONFIG, and choose OK.
Select the Startup tab and look for Still Image Monitor (STIMON).
If it is there but unchecked, put a check in the box and choose Apply, OK, and Yes to reboot the computer.
If it is missing, add STIMON.EXE to the Startup group by following these directions:
Select Start, Settings, and Taskbar.
Select the Start Menu Programs tab.
Select the Add button.
Type C:\Windows\System\stimon.exe and select Next.
Select Startup from the list and select Next.
Change the name, if you want to, and select Finish.
Repeat the steps 1-5 for HPSJVXD, but type C:\Windows\System\hpsjvxd.exe in step 4 (Skip this step if you have an HP ScanJet 4200C Scanner).
Restart the computer when finished, and the HP ScanJet scanner should work.
SOLUTION 2: Find out if any games have been installed which run in the background. If so, uninstall them and see if the error disappears. One game that has been associated with this error is called Head Rush.

SOLUTION for the HP ScanJet 4100C scanner: If Stimon and HPSJVXD are in the Close Programs screen as indicated above, then follow these instructions:

From the Windows desktop, click Start, and Run.
In the Open box, type in CONTROL.INI and click OK.
In the Control.ini window, look in the section titled [Don't Load].
If STICPL=NO change it to STICPL=YES.
Then click File and Save. Close the Control.ini window and reboot the computer.

Thank you. Power cycling the scanner several times with the USB cable disconnected worked. All the other solutions did not work.

Make sure your scanner is not plugged into a powertsrip it will build up static and then affect the connectivity with the scanner because the USB cable is not heavily shielded against static electricty you may be getting an ESD discharge into the USB cable.... Make sure you have the scanner plugged direct to 3 prong outlet some people do not have those in there houses and use adapters those are no good either if you do not have a 3 prong outlet get an electrician and get one....
Also try to keep the USB cable away from the speakers and the speaker cables and monitor they let out a lot of static electricity...
