							Jam recovery
This product provides jam recovery, a feature that you can use to reprint jammed pages. The following
options are available:
●AUTO — The product attempts to reprint jammed pages when sufficient memory is available.
●OFF — The product does not attempt to reprint jammed pages. Because no memory is used to
store the most recent pages, performance is optimal.
NOTE:When using this option, if the product runs out of paper and the job is being printed on
both sides, some pages can be lost.
●ON — The product always reprints jammed pages. Additional memory is allocated to store the last
few pages printed. This might cause overall performance to suffer.

							Solve print-quality problems
You can prevent most print-quality problems by following these guidelines.
●Configure the trays for the correct paper-type setting. See 
Configure trays on page 85.
●Use paper that meets HP specifications. See 
Paper and print media on page 69.
●Clean the product as necessary. See 
Clean the paper path on page 133.
Print-quality problems associated with paper
Some print-quality problems arise from using paper that does not meet HP specifications.
●The surface of the paper is too smooth.
●The moisture content of the paper is uneven, too high, or too low. Use paper from a different source
or from an unopened ream.
●Some areas of the paper reject toner. Use paper from a different source or from an unopened ream.
●The letterhead you are using is printed on rough paper. Use a smoother, xerographic paper. If this
solves your problem, ask the supplier of your letterhead to use paper that meets HP specifications.
●The paper is excessively rough. Use a smoother, xerographic paper.
●The paper is too heavy for the paper-type setting that you selected, so the toner is not fusing to
the paper.
For complete paper specifications for all HP LaserJet products, see the HP LaserJet Printer Family Print
Media Guide. This guide is available at 
www.hp.com/support/ljpaperguide.
Print-quality problems associated with the environment
If the product is operating in excessively humid or dry conditions, verify that the printing environment is
within specifications. See 
Operating environment on page 212.
Print-quality problems associated with jams
Make sure that all sheets are cleared from the paper path. See Jam recovery on page 180.
●If the product recently jammed, print two to three pages to clean the paper path.
●If the sheets do not pass through the fuser and cause image defects on subsequent documents,
print two to three pages to clean the paper path. If the problem persists, print and process a cleaning
page. See 
Clean the paper path on page 133.

Random image
repetition If an image that appears at the top of the page (in solid black) repeats further down
the page (in a gray field), the toner might not have been completely erased from the
last job. (The repeated image might be lighter or darker than the field it appears in.)
●Change the tone (darkness) of the field that the repeated image appears in.
●Change the order in which the images are printed. For example, have the
lighter image at the top of the page, and the darker image farther down the
page.
●From your software program, rotate the whole page 180° to print the lighter
image first.
●If the defect occurs later in a print job, turn the product off for 10 minutes, and
then turn it on to restart the print job.

Pages print but are totally blank.The sealing tape might still be in the print
cartridges.Verify that the sealing tape has been
completely removed from the print

ends and reconnect it.
●Try printing a job that has printed in

●Try using a different USB cable.
Other devices are running on your
computer.The product might not share a USB port.
If you have an external hard drive or

the same port as the product, the other
device might be interfering. To connect
and use the product, you must
disconnect the other device or you must
use two USB ports on the computer.

							Solve connectivity problems
Solve direct-connect problems
If you have connected the product directly to a computer, check the USB cable.
●Verify that the cable is connected to the computer and to the product.
●Verify that the cable is not longer than 2 meters (5 feet). Replace the cable if necessary.
●Verify that the cable is working correctly by connecting it to another 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 and show-me-how pages on page 104.
1.Are there any physical connection problems between the workstation or file server and the product?
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 product 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 product 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 on page 68.
4.Can you ping the product?
Use the command prompt to ping the product from your computer. For example:
ping 192.168.45.39
Ensure that the ping displays round-trip times.
If you are able to ping the product, verify that the IP address configuration for the product is correct
on the computer. If it is correct, delete and then add the product again.
If the ping command failed, verify that the network 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 applications 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?
