Step 1: Look for jammed paper

Find and clear any paper or media that might be stuck inside the printer.

  2. Unplug the power cord from the power source.
  3. Wait 60 seconds.

    note:
    HP recommends plugging the printer directly into a wall outlet.
Try to print again to make sure the hardware functions correctly. If the problem persists, continue to the next step.

Step 3: Service the printer
