Printer will not turn on, checked adaptor it lights until i plug it into printer

Chapter15 The Init Button
The Init button is used for maintenance: Simultaneously press Init button and turn on (by plugging
in the power adaptor) the Server until USB1 LED indicator simultaneously blinks. After that, the
Server will do the following tasks:
A. Perform a Factory Default of the MFP server, which will restore most of the parameters and
settings to factory default values,
B. Perform a TFTP server. You can upgrade new firmware using any TFTP client tool.
Note: After performing the tasks mentioned above, you have to unplug the power adaptor and then
plug in the power adaptor to restart the Server.

hi, Mr Justin Becker
i think its a power supply problem, first you should try another dc adaptor, if your printer works fine with the new one, you have to replace it or take it for repair.
if it is a DC Adaptor problem it cost about: US $29.74

HP OfficeJet Pro 8500 AIO GSA printer power supply ac adapter cord...

1) Connect the printer directly to the walloutlet..
2) Try with different wall outlet...
3) Check if the button is stuck inside or not..
4) Remove the power chord from he back of the printer and then press and hold down the power button for 30 sec... release the button and then plug in the power chord...
Check if the power button responds or not...
5) Check if there is any light on the adaptor or not or if the printer has any light or not...
if there is no LED light on the adaptor it is a problem with the power adaptor ..
If there is light on the adaptor as well as printer and power button does not respond it is an issue with the printer..
You must replace the printer...

check the power cord by replacing it, if same problem then your adaptor is bad

Check you adaptor and the power cord are they supply the power and may be the power section of printer is faulty just connect the power cord in other same printer model for testing.
Hope this helps. Please rate my response.
Thanks.
Have a good day.

Please folow these steps :-
1.disconnect the [power cable from the back of the printer
2.press and hold the power button for 20-30 seconds
3.reconnect the power cable back to the printer
4.check whether the adaptor has a green light on it or not or is it warming up
5.if the green light is not on try in a different wall outlet
6.if still it does not work then buy a new adaptor it should work or even if the adaptor does not warm up replace the adaptor
it should work
thank you

Power adapter is damaged. Get a new one on Ebay.

plug it into the wall , most newer laptops will have a power boost while plugged into AC.
check your power cable receptical on the back of the laptop, these are notorious for getting loose.
check the cable on the ac adaptor, these are bad for getting breaks that you cant see in them (run your hand down the cable physically and fell for any breaks while unplugged, then do it again plugged in and watch for lights to flicker on the computer.
look for the power light on the laptop to come on when you plug the adaptor in. if you get a light on the adaptor and on the computer, then the adaptor isnt the issue.
the next step is checking the power button and power supply.. post what your results are here and we'll move to the next step if not resolved.
Regards!

Don't Worry the HP printer are deisgned to connect without the surg protector.

Try the steps mentioned bellow

Unplug the power cord from the All-In-One as well as the power outlet when there is still power in the All-In-One. and wait for atleast 1Min
Plug the power cord directly to a wall outlet without surg protector. (if possible connect it to a different power outlet)
Before connecting the power cord to the All-In-One press and hold the # and no 6 button and then insert the power cord, do not release the keys
until you see a message a reset (if the screen goes blank then release the keys and turn the power on)

If This does not work in the power cord you will see a rectangle box like thing thats a apdptor, after plugging it to the power oulet for a couple of minitues, check and see if you can feel any heat in the adaptor if yes then the adaptor is good the power cord may be bad, so accordingly replce the power cord or adaptor:

Good Luck

its the problem in your adaptor for sure.but before going for the new adaptor please check the jack of the printer where you connect the adaptor is loose or slightly pressed inside or looks any thing like damaged.if not then try in another electric outlet.also try with different power cord wire which you connect in the adaptor the three pin adaptor.that is near about less then 2$ if you want to replace.and if still does not work then its the adaptor you have to replace.that will cost u near to $10.
