If you encounter any problems while installing or operating the HP
JetDirect 70X, here are some suggestions for solving them.
Hardware Installation Problems
Condition Possible Cause/Solution
When I press the Test
button on the back of the
home print server, no test
page or an unreadable test
page prints. Try the following. After each item retry the test.
• Be sure the HP JetDirect 70X is powered up.
The green Status light on the top of the HP
JetDirect 70X should be ON. The power
supply must be firmly connected to the HP
JetDirect 70X. The other end of the power
supply should be firmly inserted into a power
source. Make sure the wall outlet or power
strip is receiving power.
• Be sure your printer is turned on, is online,
has paper, and ink or toner.
• Be sure the parallel printer cable connecting
the HP JetDirect 70X to the printer is an
IEEE-1284 compliant cable. Be sure it is
firmly seated and working properly
(substitute a known working cable if
available).
• Turn off printer and HP JetDirect 70X; then
turn on the devices in this order: HP
JetDirect 70X, then the printer.
I can’t connect the home
print server to my
computer’s home
phoneline network. All of
the jacks are being used. • Provide additional connections using a
phoneline splitter (see the Terms section in
Chapter 1).
CAUTION: some home phoneline network
devices wil not pass network traffic through
the device’s “phone” jack.
The Status LED (light) is off. See the Indicator Lights section of this chapter.
The light on the back of my
HP JetDirect 70X is off. This is the Link Valid LED. See the Indicator
Lights section of this chapter.
