Try this: Power down the computer and printer, connect the usb to a different usb port. Reboot. The Mac should register the changed location.
The older apples used to be very sensitive to port selection and peripherials serviced. Perhaps they still are.
Make sure that the hardware is functioning correctly. Restart the product and the computer Manually check the USB connection between the product and the computer Make sure that the USB cable is connected correctly to the product Test the USB connections and restart the computer The USB cable is connected to a USB hub or a docking station for a laptop or Desktop.
Fully uninstall and reinstall the HP software Use the MSCONFIG utility to enable the Startup software Try the scan again If the scan is successful, the issue is resolved.
I uninstalled/put into trash everything on my system related to the original application. Emptied the trash. Downloaded newest drivers, etc. from HP site and installed on my Mac. Yahoo!!! Scanner works fine!
1. Try connecting the USB cable into different USB port of your Mac Leopard. 2. Make sure that your computer could detect other USB devices. 3. Try connecting the printer into different computer to see if the printer would be detected or not. 4. Use different USB cable.
If you get the same problem, you need to contact the printer manufacturer. I believe that it is more on physical connection.
This is a HP hardware/software error and HP has not fixed it.
The C4250 may report that "USB is not connected" but the printer works just fine and when you use the Microsoft Scanner and Camera Wizard to carry out a scan, it works just fine too. So the error message is wrong.
The Microsost Scanner and Camera Wizard can be found on the Control Panel.
You need to set up the software on the iMac. The reason it gives you that error message is because it can't communicate with the computer and imaging software as the computer doesn't see the scanner and can't communicate with the printer's control interface. The iMac may see the printer and be able to print without any additional software because the driver package for the printer portion may already be installed with the OS X HP printer driver support. You didn't mention whether or not you could print from OS X. I am assuming you can. Faxing and copying from the unit doesn't use the computer at all and doesn't need to communicate with it. Scanning and printing do. If you can't print either then none of the driver or support software is installed and you have to set it up. You can get the instructions for setting the printer up in OS X 10.5 from HP. Just click here and it will take you to the page with the instructions.
I now have 2 of these and both print ok but can not scan with either, never tried to till now. I have re- downloaded the driver from HP.com via Internet Explorer (usually use Mozilla Firefox) and i get 2 diff. error messages : network busy (impossible since it is connected via USB) and the 1 at my office connects wirelessly but error message is something to do with software. Thanks!
