Probable Cause 3 
Cables are not connected properly.
Corrective Action 
Check the following cables to ensure they are connected properly.
• Cables between the All-in-One printer and the hub or router
• Cables between the hub or router and your computer
• Cables to and from your modem or printer Internet connection (if applicable)
Probable Cause 4 
A firewall, anti-virus, or anti-spyware application is preventing the printer from accessing 
your computer.
Corrective Action 
Many firewall security programs have different levels of firewall security (Block All, High, 
Medium, Low), and some high levels of protection may prevent certain software 
applications and/or services from being permitted to operate through the network with 
enabled firewall security.
Via the firewall security program on your PC, manually allow inbound and outbound 
application permission through the firewall for the following services required for the 
wireless All-in-One operations:
Bonjour Service 
(C:\Program Files\Bonjour\mDNSResponder.exe)
Kodak AiO Network Discovery Service 
(C:\Program Files\Kodak\Printer\Center\EKDiscovery.exe)
Kodak AiO Device Service 
(C:\Program Files\Kodak\Printer\Center\KodakSvc.exe)
Kodak AiO Home Center 
(C:\Program Files\Kodak\Printer\Center\AiOHomeCenter.exe)

printer:
