HP printer My HP Deskjet 3930 won't turn on. All cables and power cords are plugged in.

Turn it off and see if the blinking stops.

First, check to make certain there are no small pieces of paper stuck in the gears of the rollers and carriage. You may have to reach in through the paper tray to move the carriage to see both sides. To do this, the printer must be unplugged.

If you are certain you have cleared the jam, I would do a power reset:
With the printer on -
* unplug the power cord from the back of the printer
* unplug the power cord from the wall outlet
* wait at least 15 seconds
* plug the cord back into the wall
* plug the cord back into the back of the printer
* printer should turn on by itself, if not press power button to turn on
* try to print a test page: (With printer on - while holding the power button in, open and close the front cover of the printer 4 times, then release the power button, self-test should print.)

The following link from the HP Support site is a step-by-step guide to removing paper jams. You may want to follow them to ensure you have cleared all the jams and reset the printer correctly.

The HP Product Stops Printing and the Power Light Blinks or Mechanism...

unplug printer & power cables, replug in

take cartridges out, put back in making sure sure nothing is obstructing the ink dispensary on the cartridges and that they're clean

look in the printer where the cartridges go, making sure nothing is blocking the ink getting into the printer

check the rollers to make sure no paper is caught inside the printer

turn on printer and try this

hope this works and good luck
