I have been trying to get a Ricoh 6430DN printer to connected to a Comcast cable modem so that it will be accessible to other computers on the same network.
I have connected two known good network cables from the Ricoh printer to the cable modem and have programmed both a static IP address (on the same subnet) and a DHCP address to this Ricoh network printer.
The network port on this printer and the network port that the printer is plugged into on the cable modem all have flashing connectivity lights. We have also plugged the printer into all 4 of the ports on the cable modem but the printer is still not accessible on the network.
When the printer has a static IP address it is unable to be pinged or to be connected to using a web browser.
When this printer is given a DHCP address its IP address is listed as being 22.214.171.124 (which isn't on the 10 subnet that the cable modem is on) and is also unable to be recognized on the network.
I have called Ricoh support and they haven't been able to get this issue resolved.
What else can be done to fix this issue so that this Ricoh printer will be able to communicate with the rest of the network while it is plugged into the Comcast cable modem?
