Overview

From an Apple Mac OS From a Microsoft OS Ping the Printer From an Apple Macintosh With OS X (10.x) A ping test is used to check network connectivity The IP address of the machine is required to perform this test If necessary, print a Configuration Report to obtain the IP address.  Macintosh OS X contains a Network Utility application that can be used to troubleshoot TCP/IP network communication problems The Ping utility is included in the Network Utility application and can be used to perform a ping test. NOTE: Older Mac OS versions (prior to OS 10) require a third-party utility for pinging. From the Mac: Ping the Printer From a Computer With a Microsoft Windows OS A ping test is a test used to check network connectivity The IP address of the machine is required to perform this test If necessary, print a Configuration Report to obtain the IP address.  Double-click on the [Hard Drive] icon. Double-click on the [Applications] folder. Double-click on the [Utilities] folder. Double-click on the [Network Utility] icon to open the Network Utility application. Click on the [Ping] tab. Enter the IP address of the printer in the Please enter the network address to ping field. Click on the [Send only] radio button. Type: 4 in the field provided. Click on the [Ping] button One of the following responses will be received: "4 packets transmitted, 4 packets received, 0% packet loss" This response indicates that the Mac received replies from a network device (computer, printer, etc.) with that assigned IP address This typically indicates a good connection to the machine However, if there are replies to the ping request but other network communication problems with the machine still exist (such as print jobs remain in the print queue), it is possible that a duplicate IP address exists. To test for a duplicate IP address, disconnect the Ethernet cable from the machine and ping the machine again There should not be any replies Instead, four responses of "Request timed out" should be received If there is a reply, another device on the network (for example, another computer or printer) is configured with the same IP address Contact a network administrator to resolve the TCP/IP addressing conflict. "Unknown host" or "4 packets transmitted, 0 packets received, 100% packet loss" This response indicates the ping command was sent over the network, but no device on the network received or replied to the command Contact a network administrator to resolve the problem. NOTE: Any percentage of packet loss indicates a communication problem For example, if the ping request returns only a 20% packet loss, a communication problem still exists Contact a network administrator to resolve the problem. "4 packets transmitted, 4 packets received, 0% packet loss" This response indicates that the Mac received replies from a network device (computer, printer, etc.) with that assigned IP address This typically indicates a good connection to the machine However, if there are replies to the ping request but other network communication problems with the machine still exist (such as print jobs remain in the print queue), it is possible that a duplicate IP address exists. To test for a duplicate IP address, disconnect the Ethernet cable from the machine and ping the machine again There should not be any replies Instead, four responses of "Request timed out" should be received If there is a reply, another device on the network (for example, another computer or printer) is configured with the same IP address Contact a network administrator to resolve the TCP/IP addressing conflict.

NOTE: Any percentage of packet loss indicates a communication problem For example, if the ping request returns only a 20% packet loss, a communication problem still exists Contact a network administrator to resolve the problem. From a computer, click on [Start], and then click on [Run] The Run window will be displayed. In the Open field, type: cmd and then click on [OK] A DOS Prompt window will be displayed. NOTE:   For Windows 98 / Me OS, type: command in the Open field. From the DOS prompt, type: ping xxx.xxx.xxx.xxx (where the x characters represent the IP address of the machine), and then press [Enter] on the keyboard Make sure to include a space between the word "ping" and the IP address (For example, "ping 192.1.1.100".) The computer will make four attempts to ping the machine One of the following responses will be received: "Request timed out" This response indicates the ping command was sent over the network, but no device (computer, printer, etc.) on the network received or replied to the command Contact a network administrator to resolve the problem. "Destination host unreachable" This response indicates that the computer sending the ping command is unable to communicate with the machine's network segment Contact a network administrator to resolve the problem. "Bad Command or Filename" This response indicates that either the command was mistyped or the computer is not configured to use the TCP/IP protocol Contact a network administrator to resolve the problem. "Reply from xxx.xxx.xxx.xxx: bytes=32…" This response indicates that the computer received replies from a network device with that assigned IP address This typically indicates a good connection to the machine However, if there are replies to the ping request but other network communication problems with the machine still exist (such as print jobs remain in the print queue) it is possible that a duplicate IP address exists.
