1.4.4 Solving network connectivity problems

If your printer’s LED lights are not showing as POLAR3D (blue over white), then the printer is not connected to the Polar Cloud.

If the LED lights cycled:

1.

POLAR3D →POLAR3D →POLAR3D (the LED lights cycled from entirely blue, to blue over red, before returning to entirely blue): the printer searched for the specified local network, but could not successfully connect.

(a)

For WiFi connection, first go back to the network profile configuration (step 7 in Section 1.1; see in particular Figure 1.6), and check that you entered the local network password correctly!

(b)

If using a static IP address, check that all those networking parameters were correctly entered; see Section 1.4.1.

(c)

On an advanced network, check with your network administrator that he or she has used your printer’s MAC address to permit it access; see Section 1.4.2.

2.

POLAR3D →POLAR3D →POLAR3D (the LED lights cycled from entirely blue, to blue over red, before ending as blue over yellow): the printer successfully connected to your local network, but has not been able to connect over the Internet to the Polar Cloud.

(a)

Confirm with your network administrator that the printer is being allowed access to outgoing HTTP ports 80 and 443; if your local network normally blocks access to those ports, the network administrator will need to open up access for the printer.

(b)

Check whether your site is having general Internet connectivity problems – the printer can’t connect to the Polar Cloud unless your Internet connection is operating!
