I just installed my HP officejet J6400 on my wireless. Sometimes it allows my wireless connections to work with our laptops - sometimes not. Today, not. I just tried to uninstall some programs in an effort to allow all access - still no success. I've got a Linksys wireless router throughout the house. What could be the hitch?

CALL HP SUPPORT

You can find all HP OfficeJet J6400 series driver and software HERE.
Try to de-install and re-install again when running as Administrator.
(right mouse click on the setup file)

Hi, I hope that I can help you today.

Here is a link to the HP website for your printer.

http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=3635388&lang=en&cc=us&prodTypeId=18972&prodSeriesId=3635376&taskId=135

You didn't specify which operating system that you have, so this link will allow you to choose it yourself.

This provides not only the drivers, but the software for it as well.

I know how frustrating it can be to not have the disk with the drivers and software, and I am glad I could find the appropriate link for you here today.

Windows Vista and 7 sometimes won't allow installation of devices with unsigned or unvalidated drivers. Can you bypass that message and install anyway?

* Which is the operating system of the computer?
*What are the HP entries listed in the Programs and Features lsit? (or Add/Remove programs)

Please get back to me with the above information. I can solve this problem

try a complete reinstall of the printer:
1) unplug printer
2) un-install all drivers, and make sure printer is removed from printer list
3) download the latest drivers from HP:

(the included CD drivers could be outdated)
4) follow HP instruction on how to install the new drivers and printer (sometimes it wants software first, sometimes it wants to detect printer first).

Good luck!

The printer needs to be installed by you as "Adiministrator". When installing the printer you need to hold down the "Alt" button when clicking n Add Printer function. It will then give an option of installing as Administrator.

you may need to purge stuck jobs. you do that by stopping then restarting spooler.exe. see running services ie right click my computer and choose manage. once you do that it should print. if it doesnt then its an IP address issue, print a status sheet, usually OFF then hold in button, keep holding and turn on printer it will print status sheet. check IP address is correct as per printer properties.

CHECK THE FOLLOWING AREA OR FOLDERS IN THE COMPUTER SYSTREM.

GO INTO CONTROL PANEL AND OPEN THE FOLLOWING FOLDERS:

DEVICE MANAGER,
NETWORKING AND SHARING CENTER,
PROBLEMS AND REPORTS,
SECURITY CENTER
WINDOWS DEFENDER
WINDOWS WIREWALL

I WILL TAKE A GUESS IT IS THE ANTIVIRUS AND THE FIREWALL CAUSING ALL OF YOUR PROBLEMS.
