There are a few things you can try:

1. Power reset; press and hold the Power button until it the machine starts a diagnostic mode; if this doesn't turn on the machine, unplug it for 10 minutes and upon plugging it back in, see if the error reset itself
2. Unplug all USB devices (including the printer) and reboot the computer. Once the computer has rebooted, plug in the printer, allow it to install (it should install automatically) and see if the error is corrected. Sometimes there can be a temporary conflict and the only way to solve it is to remove all other USB devices (this can work for external hard drives too).

The scanner lock switch may be in the locked position. Lift the cover and check the slide switch located on the top front left. If this is not the problem, you will have to have a service center look at the problem.
