Return it to Hewlett-Packard. These machines are susceptible to all sorts of electronics and assembly defects. They should repair or replace it under warranty if it is less than a year old, and if it is a "known" fault they will probably do something if it is older. Personally I would fill it up with concrete and use it for a garden ornament. And I used to like HP machine over all others.

Not able to switch it on

Hello Doctor,

In my OfficeJet 7410xi... it was the 802.11 card.
(endless power loop)

I opened the rear ...
pulled the 2 wire (black & white) power feed and the printer came back to life (obviously no longer WIRELESS).

The annoying little card actually lived under the front key-control panel.

Needless to say...
HP tech-support was PATHETIC (in my humble opinion). My parts came from eBay... and the procedure came from anecdotal cyber-wisdom (other BEWILDERED HP victims sharing their frustrations).

On the 7410xi less than 2" x 3" (small) card nomenclature:
HP5092-5028 (rev. A) multilayer (not-serviceable) PCB
Tyco 100902 LF
PN 1513349 (rev. C)

Hope this helps with your search...

How do I delete eprint?

Usually for HP printers not being recognized because they loose their IP address on the network or the computer can't see it.

What you can do is completley uninstall the HP software for the Officejet 8600, then go to lookup the officejet 8600 under Support > Download Drivers. download the latest full installation then run the install. When it ask you how to install it do the custom install and then only select the things you want to install.

When it ask you to do the eprint set up you can skip that part. also once install try running the HP updates for find any Network fixes or and Firmware updates.

The display screen on my hp officejet 8600 has no contrast

Some people have fixed that by unplugging everything from the wall and also the other cables overnight and then powering up again.

If that fails call HP warranty

My officejet pro 8600 is telling me to pick motor stalled. What does that mean? It will not print

I have spent many hours doing some trick to solve this , and it did not got me anywhe.
Finally last chance I powered down the printer and completely removed the second printer tray assembly from the bottom of the printer.
Powered back up running only the single main tray and that did the trick .
