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 click OK.
This command sends an echo command to the EasyLAN to check
if the PC and the printer can reach each other through the network.
The following fi gure shows a correct response to the Ping command.
The fi rst reply to the fi rst Ping command often takes more time than
the following. This is a normal behavior. The fi rst time the Ping com-
mand is executed, the PC needs some extra time to perform a "dis-
covery" of the network address (ARP request). The 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 any answer to the Ping command, then you
probably have a hardware problem.
Description:
The performance of a Wireless network connection ceases to work or the
performance deteriorates after having worked properly for some time after
installation.
Possible Causes and Suggested Remedies:
• Bad radio connection between printer and access point.
- Either the printer or the access point has been moved after installa-
tion or some kind of obstruction has come between printer and access
point. In principle, there should be a free line-of sight between the
access point and the antenna. There is also a distance limit.
Check the signal strength.
- Check network test label for statistics.
- Try moving either the printer or the access point (or both) or con-
sider fi tting a higher gain antenna.
• Slow response.
- Too many devices associated with the same access point.
