							Solve connectivity problems
Solve direct-connect problems
If you have connected the product directly to a computer, check the cable.
●Verify that the cable is connected to the computer and to the product.
● Verify that the cable is not longer than 2 mete
rs (6 feet). Replace the cable if necessary.
● Verify that the cable is working 
correctly by connecting it to anot her product. Replace the cable if
necessary.
Solve network problems
Check the following items to verify that the product  is communicating with the network. Before beginning,
print a configuration page. See 
Print the information pages on page 48.
1. Are there any physical connection problems between the workstation or file  server and the product?
Verify that the network cables, connections, and router configurations are correct. Verify that the
network cable lengths meet network specifications.
2. Are the network cables connected properly?
Make sure that the product is attached to the net work using the appropriate port and cable. Check
each cable connection to make sure that it is secure and in the right place. If the problem continues,
try a different cable or ports on the hub or transceiver. The amber activity light and the green link
status light next to the port connection on the back of the product should be lit.
3. Are the product link speed and duplex settings set correctly?
Hewlett-Packard recommends leaving this setting in automatic mode (the default setting).
4. Can you ping the product?
Use the command prompt to ping the product from the computer. For example:
ping 192.168.45.39
Make sure that the ping  displays round-trip times.
If you are able to ping the product, verify that th e IP address configuration for the product is correct
on the computer. If it is correct, de lete and then add the product again.
If the ping command failed, verify that the netw ork hubs are on, and then verify that the network
settings, the product, and the computer  are all configured for the same network.
5. Have any software programs been added to the network?
Make sure they are compatible and that they are  installed correctly with the correct printer drivers.
6. Are other users able to print?
The problem might be workstation-specific. Check the workstation network dr ivers, printer drivers,
and redirection (capture in Novell NetWare).
7. If other users are able to print, are th ey using the same network operating system?

server to check the status of other protocols. See 
Embedded Web server (HP LaserJet P2055dn,
HP LaserJet P2055x, and HP LaserJet P2035n only) on page 57.
9. Does the product appear in HP Web Je tadmin or other management program?
● Verify network settings on the Network configuration page.
● Confirm the network settings for the product using the product control panel (for products with
control panels).

							How to use the parts lists and diagrams
The figures in this chapter show the major subassemblies in the product and their component parts. A
parts list table follows each exploded view assembly diagram. Each table lists the item number, the
associated part number, and the description of each par t. If a part is not listed in the table, then it is not
a field replacement unit (FRU).
CAUTION: Be sure to order the correct part. When looking  for part numbers for electrical components,
pay careful attention to the voltage that is listed in  the description column. Doing so will ensure that the
part number selected is for  the correct all-in-one model.
NOTE:In this manual, the abbreviation “PCA” stands for “printed circuit-board assembly.”
Components described as a PCA might consist of a si ngle circuit board or a circuit board plus other
parts, such as cables and sensors.
