Ok - the reason this error pops up is because there is a software issue going on. If the software is correctly installed you will see options for where the scan will go in the computer.
Having said that there are several things that can cause a problem between the printer and the software;
1) You are connecting the printer by USB to router - you may print but will never be able to scan as this is not a networkable printer. Connect it directly to your computer and recomplete the setup portion to configure the scanner.
2) You have not finished the setup. At the end of the installer you can setup the scanner but if you skipped this step you will have to redo it in order for it to connect. Click on the device manager in your dock and then next to information and settings there will be a little wheel. Click on the wheel and go to setup assistant. Complete the assistant and try to scan.
3) The printer is not grabbing the new software options - leave the printer turned on but unplug the power cord and wait for 30 seconds. Plug printer back in - when you do this it should initialize and will look to the mac for changes and the options should load.
4) Software missing - You MUST have the software for the printer installed for scanning function. Adobe and other programs cannot replace it - it has to be installed.
5) Software is corrupted. Uninstall the software (uninstaller is under applications in the HP folder) and then download (www.hp.com) and install the most recent full feature software and drivers for your operating system.
6) If all these steps fail you may have an issue with your computer and it's TWAIN drivers.

For Mac OS 10.5.8, go to Applications/Hewlitt Packard and use the uninstall software to uninstall the old version of the driver. This is essential. Restart. Go HP website, find the C4280 and download the new version of the software 9.7.1. It is 187.98 MB. Install the software.Check apple preferences to be sure you see your printer/scanner added to the list. If you don't uninstall first, installing the newer version will not allow you to use the scan function. All you get is an error message: scanner can't be found/USB cable not connected.

Why doesn't scanner recognise usb connection


What type of device are you trying to connect to the scanner? The USB connection might not be working because the scanner can't register the device. It might also be a bad USB port. Have you tried a different device in that same port?

Can't find scanner


Is the scanner visible in Device Manager? If not you have a hardware or connection issue.

Is the connection USB or network? If network have you checked TCP/IP settings? If USB are the USB items OK in Device manager?

Is it an old scanner connected to a new Windows version such as Win7. Some old scanners are not compatible.

I dint get connection with my pc. to my USB.. it is not recognizing


Does some other USB device work properly when connected to the USB port that you are trying to use with your Transcend Barcode Scanner?

Did you try to connect the Transcend Barcode Scanner to some other computer? If so, did the other computer recognize it?

If the Transcend Barcode Scanner is "brand-new", did the packaging for it come with a CD-ROM that you need to use -before- trying to connect the Transcend Barcode Scanner to your computer?

Usb 1.0 or usb 2,flatbed scanner compatability


Find a USB device, such as a memory-stick, that is "USB 2.0" and connect it to a USB port. If Windows XP pops-up a window ("this device will perform better when connected to a USB 2.0 port"), then you have connected it to a USB 1.1 port.

Yes, you can connect a scanner, if it has a USB connection. Not all laptops have a parallel-port ("old-style" printer) port, but some scanners require a parallel-port.

Visioneer 8100 connected via USB cable.


I had the same problem. After I downloaded the driver I disconnected the scanner.
Then restarted the PC and after up, plugged in the scanner to my USB, Windows found it and installed it. Now the system recognizes the scanner. However, I am still
looking for a user manual to know how to use the scanner. I performed a scan ok to the desktop, but cannot find the document on the system. ed

Scanner or PC?


Neither is it a prob with the computer nor with the scanner.

 

Let me guess,

either is your usb connection cable longer than 2m or you have connected the usb printer/scanner cable to a usb hub.

 

Do use a cable no longer than a max of 3m and do connect the usb cable directly to the computer usb slot.
