Error message?
Just put something on the scanner glass and press the print button in the printer itself, leave the computer alone.
Did it work? if so... there's something wrong with the HP software, re-install.
That machine takes copies without the computer on, so, it should work.

reinstall drivers and restart the whole system

I found a solution to this...

HP multi units are notorious for scanner failures. It is just a weak component in their machines. I have seen this time and time again. The only solution is to change the scanner out or purchase a different machine. Just keep in mind the notoriety HP has which failed scanners. If you want to venture into the replacement of the scanner the following website might have the product you are looking for. Otherwise, search around the net for a scanner assembly unit for the OJ7310. But, be prepared scanner units are not cheap.

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.

Try unplugging the printer from the electrical source for several minutes. Unhook the printer from the computer and reboot a few times. Turn off the computer, replug the printer and turn on the printer then the computer. That should clear it. Also try printer properties and select align print heads. Let me know what happens. Good Luck, Tim
