17. Disconnect the laptop. Repeat steps 3through 5b. 18. Select "Obtain an IP Address Automatically." 19. Click on OK. 20. Reboot the laptop and all should be back to normal. Tip 4: Telnet to the Printer Only do this procedure after you have successfully pinged the NIC by following the steps in Tip 4 above. 1. At the command prompt, type the following: telnet xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the IP address of the printer. You should get a logon request. If not, reset the NIC in accordance with the NIC User's Manual. If you get a logon request, refer to the ethernet interface User's Manual for the userid and password. 2. Logon to the NIC using the proper userid and password. (For 6400, 4400, and Infoprint 6500 NICs, there is no password; you only have to use the userid root.) 3. If steps 1 and 2 are successful, you have verified that communication is established and the NIC is working. Tip 5: Printer Does Not Communicate Before doing the steps in this tip, make sure the printer has the latest microcode installed and the NIC card is the correct one for this printer. Make a configuration printout and verify that the ethernet version is the latest. Print the ethernet test page and verify the IP Address information. Do this procedure using your laptop computer with an ethernet crossover cable connected to the printer. NOTE: Read this tip completely before doing any of the steps listed below. 1.
