Scanner Drivers

[V|P]

I'm trying to use my K80 XI scanner and it keeps telling me "The computer cannot detect scanner or camera." I know Real Player causes this error, but I don't have real installed, so I don't know what else the problem is. I tried HP's software but it doesn't even install ("It can't load Java Virtual Machine", which is already running). Everything is plugged in securly. What should I do?

Are you referring to the HP Officejet K80 XI All-In-One (http://h10025.www1.hp.com/ewfrf/wc/product?product=61737&lc=en&cc=us&dlc=en&lang=en&cc=us) MFC (multi-function center/device)?

There could be any number of reasons for your MFC not being detected.

Did the MFC ever work on this or any other computer (as a printer or as a scanner)?
Look in CONTROL PANEL-> SYSTEM-> HARDWARE-> DEVICE MANAGER
Do you see any alerts or red "X"s on any of the devices?
Look in CONTROL PANEL -> SCANNERS AND CAMERAS
Does the MFC scanner show there?
Does the MFC show up in PRINTERS AND FAXES?
If so, is there more than one instance of it in PRINTERS AND FAXES?
Are you able to print to the MFC?
Right-click on it in PRINTERS AND FAXES
Choose PROPERTIES
Choose PRINT TEST PAGE
Click OK
Click OK again
Is the device connected via parallel port (DB25 to centronics cable) or USB cable?
If it is now connected via USB cable, was it connected via parallel port before (on this computer)?
If so, then the MFC software will need to be uninstalled then re-installed selecting the USB connection type when prompted.
I've seen this b4 so I have to ask; Is the MFC connected to the computer by both an USB cable and a printer (DB25 to centronics) cable?
If it is, disconnect the printer (DB25 to centronics) cable
Uninstall the MFC software then re-install it choosing the USB connection type when prompted.
I've seen this b4, too so I'll ask; is there power to the MFC?
Check the power LED (http://www.webopedia.com/TERM/L/LED.html) and the LED display to verify power to the device.
