Question about HP DeskJet 6840 InkJet Printer
I set a static IP address for our HP Deskjet 6840. Due to internet problems, our provider installed a new router the next day. Now, I can't get the printer on the network. Printer report gives IP as 0.0.0.0. It says offline. I've tried putting static IP address into browser and get that it can't connect. Also have tried resetting printer to default settings. Called our internet provider & they say it's not their problem. Is there a way to fix this? I have a hardware address, firmware revision #, & link configuration #. Nothing else. Thanks!!
Your printer is looking for your old router.
Reset the printer:

Testimonial: "This still hasn't worked. Under "Wireless Networks", it says "hpsetup", signal strength 100, network type: ad-hoc, security embedded: no, type: none, connected: no. I no longer have the CD but have downloaded the new support & drivers. Still no luck. Any other ideas? Is there a way to get back into the IP static configuration without having the IP # for the printer? I'm still getting 0.0.0.0. Thanks!"
This is a network issue, not a printer issue. Change the printer settings to DHCP, power the printer off then on again. The printer will download all the pertinent network settings and a new ip address. Turn off DHCP and assign just the last octet of the ip address. In addition, your new router may have a designated static ip range, x.x.x.100-x.x.x.150. This info you will need to obtain from your service provider.

Try flashing the firmware: one of the fixes is this - (Improved IP address management of DHCP to Manual changes). See link below.

please do not assign dynamic IP on the network printer. give a static IP on it base on your network config. and also, please do assign all you computers on the network with static IP's so that every time they boot there will be no IP conflict or problem on the network connection.

First, make sure you have plugged in a network cable CAT5 or CAT6 into the printer's network card (if you don't have one, then you can't use it as a network printer). Also, the network cable should go to a switch, hub or router.
Second, the IP address needs to be set on the printer, not through laptop. You should browse to the menus of the printer, until you find a menu Network, under this menu you should have TCP/IP sub-menu where you need to set the IP address, also there must be a Subnet Mask sub-menu and a Gateway sub-menu. This two options should be set up as well.
