Printer Scan "stops working" randomly

[Rubenfcosta]

Hello guys, i have an HP Officejet 6500 connected to my computer with USB cable and sometimes when i go to scan some documents the Printer doesn't show the PC in the screen. If i Scan from the computer with the HP Scan tool, gives me the error that connection its not possible, but if i try to scan again the Scanner works with no problem and everything starts working normally. Even the computer starts showing in the printer again.

I already unistalled the printer and installed again with recent drivers, updated the firmware and removed the "Allow the computer to turn off this device to save power" from the USB controllers in the Device Manager. But this keeps happening randomly like two times a week. I didn't had a change to switch the USB cable (i need to get one) but I switched the usb port.
