My printer will not come on at all. i have the adapter in to the wall jack but nothing happens. i have checked to ensure the wall jack works.


Solution one: Make sure the electrical outlet works
Unplug the power cord from the electrical outlet.
Plug another appliance into the electrical outlet to make sure the outlet works.
If the electrical outlet does not work , plug the product into another outlet that does work.
If the electrical outlet works, but the product still does not turn on , continue to the next step.
Solution two: Make sure the power supply is compatible with the HP product
The term power supply refers to both the power module and the power cord.
NOTE: To make sure that your product and power supply are compatible, HP suggests you use the original power supply shipped with your product.
Example of a power module Example of a power cord
NOTE: The power module might have a permanently attached power cord, or the power cord might detach from the power module.

Make sure the voltage and amperage specifications printed on the power supply match the voltage and amperage specifications printed on the HP product.
Voltage and amperage specifications printed on the power supply Voltage and amperage requirements printed on the HP product

If the voltage and amperage specifications between the product and the power supply are compatible, make sure the connector on the power cord is the same shape and color as the connector on the HP product.
WARNING: Do not force a power cord into an HP product that is incompatible with the HP product (different shape or size).

If the power cord is not compatible with the product, replace the power cord with a compatible cord. To buy a compatible cord, right-click the following link, How to Buy HP , and then click Open in New Window .
If the power cord is compatible with the product, but the products still does not turn on, continue to the next step.
Solution three: Reset the power module and test the power
Step one: Reset the power module
The power module has a safety feature inside that protects the product during a power surge. If you experienced a recent power surge, the power module might need to be reset. Use the following steps to reset the power module.
Unplug the power supply from the rear of the product.
Unplug the power cord from the electrical outlet, power strip, or surge protector.
If the product uses a power module with a detachable power cord, disconnect the cord from the power module.
Wait 15 seconds.
Reconnect the power cord to the power module.
Plug the power cord back into the electrical outlet. Do not use a power strip or surge protector.
Check to see if the power module has an LED.
If the power module does not have an LED, continue to the next step.
If the power module has an LED, check to see if the LED lights up.
If the LED does not light up, contact HP to replace the power module. To buy a compatible power module, right-click the following link, How to Buy HP , and then click Open in New Window .
If the LED lights up, continue to the next step.
Step two: Test the power on the All-in-One
Follow these steps to test the power on the product.
Reconnect the power supply to the rear of the product.
Press and quickly release the Power button to start a Power On/Off cycle. Do not hold the button down.
Figure 1: Press and quickly release the Power button

If you press and hold the Power button too long, the product might turn on and then off without restarting. If this happens, press and quickly release the Power button again.

If these steps resolved the issue , there is no need to continue troubleshooting.
If the issue persists , see the next step.
Solution four: Test the power with a compatible power cord from a different product
If you have another available power cord that is compatible with your product, use the alternate cord to repeat the steps in Solution three: Reset the power module and test the power .
If the product turns on with the alternate power cord, the original power cord caused the issue. Contact HP to replace the power cord. Right-click the following link, How to Buy HP , to buy a compatible power cord.
If the product does not turn on with the alternate power cord, continue to the next step.
Solution five: Service the HP product
If you have completed all the preceding steps and are still experiencing a problem, service the product.

    The all-in-one product does not turn on If the all-in-one product does not turn on at all, try the following actions in order to determine the cause:
    1. Unplug the power supply from the wall outlet.
    2. Unplug the power supply from the back of the printer.
    3. Remove the product cable from any power strips or surge suppressors, and plug it directly into a grounded (three-prong) wall outlet.
    4. Wait at least 20 seconds, then, plug in the supply back into the wall outlet.
    5. Plug in the power supply back into the printer.
    6. Press the power button to turn the printer on.
    7. For models that have an external power supply module, verify that the power supply module is plugged in correctly. Some power supply modules have a green LED built into the connector end or on the power supply module. This LED will be lit if power is present. If the LED is not lit, replace the power supply module.
    8. Plug the power cord into a different electrical outlet. If the all-in-one product has an ADF with an external cable plugged into the back of the product, use the following procedure:
      1. Turn off the unit.
      2. Unplug the power cable from the wall outlet.
      3. Unplug the ADF cable from the back of the product.
      4. Plug the ADF cable to the back of the product.
      5. Plug in the power cable to the wall outlet, and turn on the power.
        1. If no change, the problem is not the ADF.
        2. If the problem clears, turn off the all-in-one, unplug the power cable, and reconnect the ADF.
        3. If the error returns, the ADF is defective. Contact HP Customer Care to get the ADF replaced.
    9. Disconnect the computer parallel cable from the back of the all-in-one product and try to turn on the product again. The computer might be grounding out through the parallel port. If this corrects the issue, check the grounding of the computer and outlet.
