When I put something on the screen of my HP2400 and press the scanner button I get a message USB must be connected. But it is. The printer works fine. What am I to do? Thanks.
Hi,,
Try the steps which i have given.
1.Right click on MY computer ->Properties->Hardware->Device manager.
2.You will get Device manager window popping out.
3.Scroll down to "Universal Serial BUS controllers".Click on the (+) sign.
4.Check for the "USB Composite Device" and right click on it, click Uninstall.(IMPORTANT NOTE:wE HAVE TO UNINSTALL THE PRINTER'S USB COMPOSITE DEVICE, TO KNOW WHETHER IS THE PRINTER'S USB COMPOSITE DEVICE, RIGHT CLICK ON USB COMPOSITE DEVICE AND PROPERTIES,look for wat location says, Eg -LOCATION : HO DESKJET F300)
5.Disconnect the USB and reboot the PC.
6.Connect the USB after reboot, you will get popup "Found new hardware".Then the Drivers will be installed Automatically.
::::::::IF THIS DOESNT WORKS TRY THE BELOW ONE:::::::::::

2.A window will open and click EDIT menu-> select all, then delete all the files and folders.

4.Look for service called "HPZ PML Driver", Doubled click on it, check whether the "startup type" is "Automatic", if not changed it to automatic.Checked the "Service status" is "started".If not click on "start" button.Click Apply and OK.
