Officejet Pro 8600 won't start, has steady green power light

[JonathanDaniels]

Power button light is on, but does nothing.
Nothing else really responds, when I unplug it the light goes off, when I plug it back in it comes back on.

I've tried cycling it in all those different support suggestions. No luck.

Welcome to the HP Forums!

I understand the Office jet Pro 8600 won't start though the power button light is on,

I'll be glad to help you out, however, for an accurate solution I will need more details:

What is the product number of your product? Use this link to find it: http://support.hp.com/us-en/document/c03754824 

Have you attempted any steps on your own before posting on the HP Forums?

Which operating system are you using the printer with?

In the meantime, please try the below steps:

Depending on the printer model, the power supply might include a power module inside the printer (internal), a power module that is separate from the printer (external), or a rechargeable battery if you have a mobile printer.

It is an OJ8600 CM749A model N911a

It has an internal power module, & I have tried all the power cycling steps in the video and on that page.

Thank you for the update,

I appreciate your time and efforts,

If you've already performed the steps mentioned below:

• Unplug the power cord from the printer and wall
• Take out the toner/cartridges
• Wait 30 sec
• Plug the power cord back into the printer and wall (Make sure the printer is plugged into the wall and not a surge protector)
• Insert the toner/cartridges back into the printer

And yet, if the issue persists, please Contact HP to set up a hardware service to have your printer either repaired or replaced (free of charge if covered by HP Warranty):

I called them & they just tried to sell me a new printer. The prices are less expensive at several other stores so I wouldn't buy through them.

I've seen many people have had this issue on the forums.. many their printer just starts working later & nobody seems to know why.

Should I reset the cmos battery or the internal power supply on it & give it another try?

I mean the solution to unplug it and take out the cartridges seems pretty basic.

Hi @JonathanDaniels,

Thank you for the replying,

I appreciate your time and efforts,

If you have already performed the steps suggested by Riddle_Decipher, I would suggest this could be a printer hardware itself. 

Printers don't have CMOS battery, they only have lithium battery for mobile printers, 

You could definitely try reset the internal power supply and check if that helps.

I hope this helps. Let me know if you need any further assistance. I'll be more than happy to help.

It's been a pleasure interacting with you and I hope you have a good day ahead.

How can I reset the internal power supply?

[Jeet_singh]

Hi @JonathanDaniels,

Thank you for replying,

I mean by performing a Hard reset or Power drain on the printer, If nothing happens, I would suggest this could be a printer hardware. Please follow the steps suggested in the previous post for further assistance.

Yes, I've done the steps & im asking about the internal power supply and the cmos that is keeping it on when I unplug it.

There is no way to check power indicator lights etc on the internal power module like it says in the video.

If I just unplug the internal module skll it reset?
