HP Officejet Pro 8600 Network connection error message in EWS

[shimheric]

I just got an Officejet Pro 8600 Premium.  The printer is connected to the network via a network cable.  When navigating through the EWS, sometimes the message "Network connection error.  Check network and try again." message is shown (the message could appear in various pages, such as Settings, Tools, etc.).  Refreshing the page should get rid of the message. 

At first, I suspected if it was a problem with the network. So I pinged the printer's ip address continuously.  It did not miss a single beat.  The printer prints and scans well via the network.  So I think the error may be caused by something inside of the print, such as bug of EWS software, or internal error. 

Anyone see the same message during the use?  Any suggestion?  Does it indicate there is hardware problem with the printer?  Thanks.

I just set up my 8600 Premium and I'm experiencing the same thing.

Thanks for reply.  I did more tests.  The good news is it is not likely caused by hardware issue, or bad network connection .  EWS is perfectly fine on Firefox. 

HP support blames IE, which is typical.  But in my opinion, it is up to EWS to accommodate both popular browsers.  Obviously they handle certain stuff differently.  Fortunately, EWS still works on IE, just not as great as on Firefox.

I have the same issue on Firefox and Chrome.

I only have one system that can use IE so I hope they fix the issue for other browsers.

I will update HP Support that the issue could exists on other browsers so that they don't have that excuse.

I also see the same problem on Safari.

I testing using a Windows 7 system with IE.  It's working better, but I got the same message once.

I also noticed that I was unable to change any settings in Settings->Administrator settings unless I used IE.

The EWS is definitely broken.  It should work with all the major browsers.

HP Support has escalated the case.  I referred this thread in the support request.  Hopefully, they can have a look at the issue.

For me, the only setting does not stick is "Use the same time zone set on this computer" in Settings\Date & Time.  I've created another ticket for this issue.  8500A has the same problem.

You can try to restart the EWS.  Unplug the power cord while the printer is on.  Then wait 15 sec and reconnect the power cord.  Press the power button if the printer does not turn on by itself.

If you would like to reset to the printer and reconfigure from scratch, you can check here: http://h30434.www3.hp.com/t5/Printer-All-in-One-Install-Setup/How-to-reset-Officejet-Pro-8600-Plus-P...

I've power cycled the printer.  That hasn't cleared up the messages with the browsers, but after power cycling the messages appear more frequently in IE.

The power cycle did clear up the problem I had setting up the email server.

Restart and reset are not meant to solve the network error message issue.

I had trouble enableing web scan.  And restarting ews solved it, similar to your case.  🙂
