							Scan-quality problems
Preventing problems
The following are a few simple steps you can take to improve copy and scan quality.
●Use the flatbed scanner, rather than the automatic
 document feeder (ADF) input tray, to scan.
● Use high-quality originals.
● Load the media correctly. If the media is  loaded incorrectly, it might skew, which causes unclear
images. See 
Loading media into the input trays  for instructions.
● Adjust the software settings according to how you
 plan to use the scanned page. See 
Scanner
resolution and color for more information.
● If your all-in-one frequently feeds more than one 
page at a time, the separation pad might need
to be replaced. Contact HP Customer Care. See 
HP Customer Care  or the flyer that came in the
all-in-one box.
● Use or make a carrier sheet to protect your originals.
Solving scan-quality problems

Blank pagesThe original might have been loaded
upside down.In the automatic document feeder
(ADF), put the top end of the stack of
originals into the ADF input tray, with
the media stack face-up and the first
page to be scanned on top of the stack.
On the flatbed scanner, place the
original document face-down with the
upper-left corner of the document at
the lower-right corner of the glass.

							Network problems
Verifying that the all-in-one is on and online
To verify that the all-in-one is on and online
Check the following items to make sure the all-in-one is ready to print.
1.Is the all-in-one plugged in and turned on?
Make sure that the all-in-one is plugged in and  turned on. If the problem persists, you might
have a defective power cable, power source, or all-in-one.
2. Is the all-in-one  Ready light on?
If the light is blinking, you might need to wait until the current job is completed.
3. Is the all-in-one control-panel display blank?
●Make sure the all-in-one is turned on.
● Make sure the all-in-one is installed correctly.
4. Does a message other than  Ready appear on the all-in-one control-panel display?
● See your all-in-one documentation for a complete list of control panel messages and
corrective actions.
Resolving communication problems with the network
To resolve communication problems with the network
Check the following items to verify that the all-in-one is communicating with the network. This
information assumes you have already printed a Network configuration page (see 
Configuration
page
).
1. Are there any physical connection problems between the workstation or file server and the all-in-
one?
Verify that the network cabling, connections, and router configurations are correct. Verify that
the network cable lengths meet network specifications.
2. Are your network cables connected properly?
Make sure that the all-in-one is attached to the network using the appropriate port and cable.
Check each cable connection to make sure 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 all-in-one should be lit.
3. Are the link speed and duplex settings set correctly?
Hewlett-Packard recommends leaving this setting in automatic mode (the default setting). See
Link speed and duplex settings .
4. Can you ping the all-in-one?
Use the command prompt to ping the all-in-one from your computer. For example:
354 Chapter 13   Troubleshooting ENWW
 
						

							ping 192.168.45.39
Ensure that the ping displays round-trip times.
If you are able to ping the all-in-one, verify that the IP address configuration for the all-in-one is
correct on the computer. If it is correct, delete and then add the all-in-one again.
If the ping command failed, verify that the network  hubs are on, and then verify that the network
settings, the all-in-one, 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 may be workstation-specific. Check the workstation network drivers, printer
drivers, and redirection (capture in Novell NetWare).
7. If other users are able to print, are they using the same network operating system?
Check your system for proper network operating system setup.
8. Is your protocol enabled?
Check the status of your protocol on the Network configuration page. See 
Configuration page .
You can also use the embedded Web server or HP ToolboxFX to check the status of other
protocols. See 
Using the embedded Web server or HP ToolboxFX .
9. Does the all-in-one appear in HP Web Jetadmin or other management program?
● Verify network settings on the Network configuration page.
● Confirm the network settings for the all-in-one using the all-in-one control panel.

							Control-panel display problems
CAUTIONStatic electricity can cause unexpected black lines or dots to appear on the all-in-
one control-panel display. Do not touch the  all-in-one control-panel display if there is a chance
that you have collected a static electric charge (for example, by walking on carpet in a low-
humidity environment).
Unexpected lines or dots might appear on the all-in-one control-panel display, or the display might
become blank if the all-in-one is exposed to an  electric or magnetic field. To resolve this problem,
perform the following procedure:
1. Turn the all-in-one off.
2. Remove the all-in-one from the electric or magnetic field.
3. Turn the all-in-one on again.
Stapler problems (HP LaserJet 3392 all-in-one)
The convenience stapler is designed to be free of staple jams. To reduce the risk of staple jams,
make sure that you staple 20 or fewer pages of media (80 g/m2 or 20 lb) at a time.
