If the printer uses a power module

Follow the steps below to ensure power is properly supplied to the printer:

   1.
      Check the power module part number against the part number listed in the User’s Guide to ensure the proper power adapter is being used.
   2.
      Disconnect the power cord or adapter from the wall outlet.
   3.
      Disconnect the printer data cable from the printer.
   4.
      Disconnect the power cord from the printer, wait thirty seconds, then reconnect the power cord to the printer.
   5.
      Disconnect the power cord from the power module and reconnect the power cord to the power module. This may not be necessary if the power module has a permanently attached power cord.
   6.
      Reconnect the power cord directly into a working wall outlet. If the power cord was plugged into a surge protector or power strip, plug the power cord directly into a wall outlet instead.
         NOTE:    "The HP Photosmart 8100, 8400, and HP Deskjet 6000 series printer power cords feature a green LED built into the power plug. If the LED is not glowing, the power module may have failed. Proceed to step 7 below.
   7.
      If the printer still will not turn on or the power LED built into the power cord is not glowing, plug the printer into a wall outlet in another room. If the printer or power LED turns on when connected to an electrical outlet in another room, there is a problem with the power in the original room.
   8.
      If there is still no power to the printer, then the power module, cord, or printer may be defective. Try the power module/cord on another HP Deskjet or Photosmart printer, of the same model if possible, to see if the power module is functioning. If the power LED is still not glowing, the power module may be defective. Replace the power module and cord.
   9.
      If the power module/cord works on the other printer, then this printer is defective. Service your printer.
  10.
      If you cannot determine whether the problem is the printer or the power module/cord, or if another printer is not available to test with, replace the power module/cord first. If this does not resolve the issue, service your printer.



If the printer uses only power cord

   8.
      If the power cord does not work on the other printer, it is defective. Replace the power cord.
   9.
      If the power cord works on the other printer, then this printer is defective. Service your printer.
  10.
      If another printer is not available to test with, carefully inspect the power cord for damage.
  11.
      Inspect the power cord for visible damage. If the power cord is damaged, replace the power cord first. If this does not resolve the issue, or if the power cord looks fine, then service your printer.
