Verifying Subnet Mask; Pinging The Printer - Intermec EasyCoder PF2i User Manual

Chapter 7 — Troubleshooting

Verifying Subnet Mask

Check subnet mask of PC and printer and make sure they belong to the
same segment. For example:
If they have the
subnet mask
255.255.255.0
255.255.0.0
255.0.0.0
In case the addresses are not in the same network segment, the printer
may not be reachable from the LAN side. Check the confi guration with
the administrator.

Pinging the Printer

Start the Command Prompt. In the Command Prompt, type Ping
<printer IP-Address> and then hit Enter.
Th is command sends an echo command to the EasyLAN to check if
the PC and the printer can reach each other through the network. Th e
following fi gure shows a correct response to the Ping command.
Th e fi rst reply to the fi rst Ping command often takes more time than the
following. Th is is a normal behavior. Th e fi rst time the Ping command
is executed, the PC needs some extra time to detect the network address
(ARP request). Th e Ping command makes the printer's network LED
fl ash green.
If you have completed the test procedure and all the conditions are met,
but you do not get a response to the Ping command, then you probably
have a hardware problem. Check the following:
- Th e LED should occasionally fl ash green when the cable is plugged in.

The numbers in the PC and Printer IP addresses have
to be

<Same>.<Same >.<Any >.<Any >
<Same>.<Any >.<Any >.<Any >
