Connecting a Oki C5300N as a 2:nd printer in my Mac-network..

Good Day Joromich,

Sounds like your problem is just an IP address conflict. The easiest way to fix this is going to be through the front panel of the printer. You will need to configure the NIC to DHCP AUTO. This will allow the switch/router to configure the printer to the IP address schema your network is using.

You should also check you switch/router settings to ensure if you are using MAC address filtering (this has nothing to do with your Mac computer). The MAC address is the physical hardware address of any NIC device. It is the "permanent" device identifier that the manufacturer has assigned to the NIC. If your switch/router is configured to use MAC address filtering you will need to know this address. It will be a series of HEX values similar to this:

AE:02:4F:3B:55:2F

And is usually located on a sticker on the outside of the NIC adapter, if not you might need to remove the card from the printer to check it, however you should be able to obtain a NIC configuration page from the printer through the control panel. If you are using this additional level of network security (helps to prevent rogue devices from attaching to the network), you will need to add the MAC address to the switch/router filtering table. Most home network users do not use this additional layering of security, but when using wireless access points/routers, every extra bit of network security helps.

Once you have reconfigured the printer for you network IP schema through the use of DHCP, the network should now see the device. If you are configuring your printer drivers to print to the IP address of the device, you should disable the DHCP AUTO setting once everything is working. Otherwise the switch/router will replace the printer IP address once the lease is expired then causing your printer not to be accessible again.

Once the switch/router has provided the new printer with an IP address, you will be able to access the internal web page of the printer through your Internet browser. At this point you can then change the IP address configuration to DHCP OFF. This will prevent the printer NIC from making an IP address request and keep the IP address that has been assigned as a STATIC address.

Configuring the printer driver on the Mac is easy, once the device has been added to the network, the Mac Add Printer Utility will see the IP address of the printer and you can use this to print directly to it rather than using AppleTalk. As for problem of not having the orignal install CD, not a problem as the printer is listed within the Mac OS printer table. If you want to use the Oki OEM driver follow the link listed here:

Select the one you want and install it as usual. Hope this helps get you going.

Cheers, Happy New Year!
