I lost my manual and my scanner keeps saying it's not connected but everything is plugged in...help?


Hi,

It seems that scanner drivers are unable to establish communication with the scanner hardware. Please try the below steps to reload the communication drivers.

1. Click start ->Run.
2. In the Run window, type "devmgmt.msc" (without quotes), click OK.
3. Device Manager Window will pop out, in this screen at the bottom you will see "Universal Serial Bus Controllers"
4. Click on the(+) sign next to "Universal Serial Bus Controllers" and look for "USB Composite Device".
5. Right click on "USB Composite Device" and select Uninstall.(Read Note)
6. After the the device is uninstalled, disconnect the USB cable from the back of the computer.
7. Restart the computer, after the system is booted plugin the USB cable.
8. You may need to wait for sometime for the device installation to get complete.
9 . Then try to scan.

Note: Before uninstalling the "USB Composite Device" right click on it and select properties to confirm whether that driver is for the printer.


Thanks & Regards,
Riztech

Printer unable to communicate with computer.


Are you using the wireless network printer function or is the printer connected by a USB cable? If you are using the wireless network, launch the printer's Wireless Setup Utility and run through it. (Check for problems with IP, signal strength etc.)

For USB, try resetting the printer (unplug it from the wall for 10 seconds). Check that the computer is looking for the printer on the correct port. Click Start > Settings > Control Panel. Double click on the Printers folder and right click on your Lexmark printer. Choose Properties then click on the Ports tab. Check that one of the USB port options is checked. (If you have a newer OS, Start > Devices and Printers and then right click on the printer.) Also try a new USB cable and a different USB port. If you have a print server or USB hub, try a direct connection.

I hope this helps.

Usb to i pod or hitachi camera


Hi,

i,d suggest that the ports are incorrectly wired on the motherboard headers, Or possible Bent Pin on the USB shorting out, when device is connected. 5V+ and 5V- will cause the computer to Arc, and restart.

Make sure the camera is on and STORAGE is selected on the camera screen when connected to the computer. You will need to have STORAGE highlighted and select OK on the camera as this starts the camera and computer to communicate. Once communication established the LCD screen of the camera goes dark and the computer should generate a removable disk drive. Check the System Tray (lower right corner beside the PC time) for Safely Remove Hardware. When you click on it, it should read "Safely Remove USB Mass Storage Device Drive ?:" If you dont see that, then check the Device Manager to see if the camera is recognized as USB Mass Storage Device. The camera uses the driver usbstor.

Desk top APC UPS ES750 not communicating


Here is an answer I got from APC when one of my client got the same problem as you did:

The error message would pop up if the link between the computer and the UPS is weak. I cannot rule out a problem with the cable or the UPS. In order to confirm the same please try the following steps which might help :

1) Ensure that the USB cable is properly connected to the USB port of the computer.

2) If the PC was powered on before the UPS, communication will not be achieved until you disconnect and reconnect the USB cable to the host. In this case, you need to disconnect and reconnect the USB cable to establish communication.

3) Some other software is polling your USB port for another device, thus causing the UPS software to temporarily lose communication with your UPS. If this is the case, you would need to shut down that application.

4) If you have any other USB devices connected to the PC, disconnect them and then try plugging in the cable.

If the issue persists, please visit the following link which lists few troubleshooting steps :

Initialization failed - Unable to acquire TWAIN-compliant device


Hello,

 

I have seen your message stating that "Initialization failed - Unable to acquire TWAIN-compliant device" error is received when trying to connect USB-Parallel type to your Laptop.

 

Well,  Printer  Panasonic UF4100, recommends to use only " Printer/Scanner Interface as Bi-directional Parallel (IEEE1284) " means you need to use Parallel cable to connect Printer to the Computer/Notebook.  You may receive some communication error messages if you are using a  "PORT REPLICATOR CABLE"( USB TO PARALLEL connector).  The error message that you have received is related to the communication error. Futher, if you use same USB- Parallel cable for long time the Printer Hardware functionality might go bad, since Printer memory gets confused and will not read or detect the Cable , since it is not a cable to use  mentioned by Panasonic Manufacturer.

 

Let me tell you, general functionality of Printer like Printing would work even if you use USB-Parallel cable. But it is not a case with Scanner and Fax functionality.

 

Hence, I recommend you to use only Parallel cable to connect your Printer to the Laptops.

 

I hope that this will resolve the issue for you.

 

You can email me at thumuvikram@rediffmail.com if you need further assistance.

 

Bye.
