Question : Problem: PC can't find 5200c scanjet
|
|
The scanner was working just fine for 3 months. Then I went to turn it on, and got the message that the PC couldn't find the scanner. There's no indicator of an IRQ conflict; the HPScan & STIMON .EXE commands are both there; there's 88% sys resources free; 128MG ram;I've tried to uninstall & reinstall--same message pops up; I tried to "hot-plug" it --didn't get the dialogue. The device mgr shows no problem with the USB ports. PC is a Gateway Performance 500 w/PentIII ???

check your bios make sure that the USB is enabled
Uninstall the scanner software reboot then once you are in windows hit ctrl,alt,delete and end task everything except for explorer and systray then reinstall
if that fails then try this below
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 download 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 scanner, 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.

WARNING: Do not change any other settings in the BIOS this could cause other computer hardware not to work.

HP ScanJet Scanners - USB Scanner Quits Working or Is Listed as an Unknown Device "Scanner Could Not Be Initialized"
ISSUE: The HP ScanJet scanner quits working after it has functioned previously, it reports "Sorry, scanner not found" or "Scanner could not be initialized". The scanner may also appear as an Unknown Device under the USB or Other Devices category in Windows Device Manager.
SOLUTION: Update the scanner's INF file and rename Unknown.inf. Use the following instructions to complete this procedure:
Select Start, Settings, and Control Panel.
Double-click the System icon and select the Device Manager tab.
Highlight the entry for the scanner, or the Unknown Device, and select Remove.
Choose OK to remove the device.
Disconnect the scanner from the PC and unplug it.
Close the Device Manager and the Control Panel.
Select Start, Programs, and Windows Explorer.
Select the Windows directory; then, select the INF subdirectory.
--------------------------------------------------------------------------------
NOTE: If the INF subdirectory does not appear, go to the Taskbar and click "View". From the drop-down window select "Folder Options" and then "View" (in Windows 95 select "Options" and then "View"). Make sure that "Show all files" is selected and that "Hide file extensions for know file types" is not selected.
--------------------------------------------------------------------------------
Find and select the file Unknown.inf; select File and Rename from the menu.
Rename the file "Unknown.old" and press, ENTER.
Follow these steps for your version of Windows:
Windows 95--Find the file Scanjet.inf and verify that it is 5 KB in size.
Windows 98--Find the file Hpscan.inf and verify that it is 10 KB in size for the HP ScanJet 6200 and 6250C scanner, 9 KB for the HP ScanJet 4100C scanner, and 36 KB in size for the HP ScanJet 5200C scanner. The HP ScanJet 4200C scanner has its own *.inf file; hp4200c.inf, and should be 10 KB in size.
If the file from step 11 is not the correct size (does not match the size listed for your version of Windows), delete the file and reinstall the HP Scanning Software from the CD. Then, go to step 16.
--------------------------------------------------------------------------------
NOTE: Windows 98 users: check to see if your system contains the following directory: C:\Windows\Inf\Other. If this file exists and contains the file Scanjet.inf, delete Scanjet.inf and then proceed.
--------------------------------------------------------------------------------
If the file from step 11 is the correct size, double-click the file to open it in Notepad.
Press the SPACEBAR and then the BACKSPACE button on the keyboard.
Close Notepad; be sure to select Yes to save the changes to the file.
Download the file SJ435EN.EXE from the HP Web site. Click here to go to the HP ScanJet Support Web site for the HP ScanJet 6200C scanner (the patch works for all HP USB Scanners), then click Drivers and Support.
Select the button near the bottom of the page titled Download Now.
You will be prompted to save the downloaded file on your local PC. Specify a location, then select Save.
Once the file has finished downloading, open the folder it is saved in, and select SJ435EN.EXE, then select Unzip. The file will be unzipped in the directory: c:\sj435usb.
Open the directory c:\sj435usb and select the file Setup.exe.
Restart the computer. After the PC is back up, plug the scanner back in and "New Hardware Detected" should appear. After reloading the drivers the HP ScanJet scanner should work normally.
--------------------------------------------------------------------------------
NOTE: It may be necessary to select Setup.exe twice in order to complete the installation. This applies to all HP ScanJet scanners that use a USB interface. The HP ScanJet 4100C, 4200C, 5200C, 6200C, and 6300C families of scanners are included in this category.

HP ScanJet Scanners - Scanner Not Found When Connected to the USB port; Verifying Connectivity and USB Functionality
ISSUE: The HP ScanJet scanner is not found when attached to the Universal Serial Bus (USB) on your PC.
SOLUTION: Verify that the cable, HP ScanJet scanner, operating system, and USB ports are configured properly by checking the following.
Turn off the computer and scanner (unplug the scanner).
Remove the cable from both the scanner and the USB port on the computer. Then, reconnect the cable. Ensure that the cable is inserted firmly on both ends; the cable must be inserted completely into the computer's USB port.
It is important that both units be turned off for at least 60 seconds before being restarted. Restore power beginning with the scanner and then the computer.
Place the HP Scanning software CD in the CD-ROM. If the main install menu appears, choose Exit.
From the Windows desktop, select Start, Run, type in D: and press ENTER (where D: is the CD-ROM drive letter).
Select the file USBMGR.EXE and double-click it. This will tell you if your computer has USB capability.
--------------------------------------------------------------------------------
NOTE: The HP ScanJet Scanners 3300C, 4200C, and 6200C families only ship with the USBMGR.EXE utility. If the scanner you have is a HP ScanJet 4100C or 5200C family, click here, to download the USB patch SJ435EN.EXE. In the Search window type in the file name: SJ435EN.EXE, then press the Search button.
--------------------------------------------------------------------------------
Verify that the USB is set up properly using the following steps:
From the Windows desktop, select Start, Programs, and then Control Panel.
Select System and then Device Manager.
From the device list, select Universal Serial Bus Controller. It should contain two subcategories: USB Root Hub, and a second line describing the PC's own specific serial USB chipset. The actual order of the two lines does not matter.
If any of these three lines are missing, a problem exists with the computer's USB configuration. To troubleshoot this problem, contact your PC manufacturer, or the manufacturer of your USB card.
--------------------------------------------------------------------------------
NOTE: You may also test your USB with a utility called USBREADY, which is available for download at: www.usb.org.
Other documents to refer to are "How to check your PC for USB compatibility before purchasing an HP ScanJet scanner for your USB interface."
You may have your USB port disabled from your BIOS, refer to your PC manufacture.
if all of this fails then the final things i would try is
try another usb cable
Try disabling anti-virus when scanning
If you have any other devices connected to the USB or serial port uninstall them completely this includes digital cameras and scanners
finally go into bios and check your parallel port mode make sure it is set on ECP a lot of pc's chipsets share the usb chips with the parallel port chips one not working right can mess up the other
