							Solve general problems
If the product is not responding correctly, complete the steps in the following checklist, in order. If the
product does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolves
the problem, you can stop without performing the other steps on the checklist.
Troubleshooting checklist
1.Make sure the product Ready light is on. If no lights are on, complete these steps:
a.Check the power-cable connections.
b. Check that the power switch is on.
c. Make sure that the line voltage is correct for the product power configuration. (See the label
that is on the back of the product for voltage requirements.) If you are using a power strip and
its voltage is not within specifications, plug the product directly into the wall. If it is already
plugged into the wall, try a different outlet.
d. If none of these measures restores power, contact HP Customer Care.
2. Check the cabling.
a.Check the cable connection between the product and the computer or network port. Make
sure that the connection is secure.
b. Make sure that the cable itself is not faulty by using a different cable, if possible.
c. Check the network connection. See 
Solve network problems on page 124.
3. Check to see if any messages appear on the control-panel display. If any error messages appear,
see 
Interpret control-panel messages on page 102.
4. Ensure that the paper that you are using meets specifications.
5. Print a configuration page. See 
Print the information pages on page 70. If the product is connected
to a network, an HP Jetdirect page also prints.
a. If the pages do not print, check that at least one tray contains paper.
b. If the page jams in the product, see 
Clear jams on page 107.
6. If the configuration page prints, check the following items.
a.If the page does not print correctly, the problem is with the product hardware. Contact
HP Customer Care.
b. If the page prints correctly, then the product hardware is working. The problem is with the
computer you are using, with the printer driver, or with the program.
7. Select one of the following options:
Windows : Click Start, click Settings , and then click  Printers, or Printers and Faxes . Double-
click the name of the product.
-or-
Mac OS X : Open Print Center  or Printer Setup Utility , and double-click the line for the product.

							8.Verify that you have installed the printer driver for this product. Check the program to make sure
that you are using the printer driver for this product.
9. Print a short document from a different program that has worked in the past. If this solution works,
then the problem is with the program you are using. If this solution does not work (the document
does not print) complete these steps:
a.Try printing the job from another computer that has the product software installed.
b. If you connected the product to the network, connect the product directly to a computer with
a USB cable. Redirect the product to the correct port, or reinstall the software, selecting the
new connection type that you are using.
Factors that affect product performance
Several factors affect the time it takes to print a job:
● Maximum product speed, measured in pages per minute (ppm)
● The use of special paper (such as transparencies, heavy paper, and custom-size paper)
● Product processing and download time
● The complexity and size of graphics
● The speed of the computer you are using
● The USB connection
● The printer I/O configuration
● The amount of memory installed in the product
● The network operating system and configuration (if applicable)
NOTE:
Although additional memory can improve how the product handles complex graphics and
improve download times, it will not increase maximum product speed (ppm).
Restore factory settings
Use the  Restore defaults  menu to restore factory settings.
1. Press  OK.
2. Press the down arrow 
 to select  Service, and then press  OK.
3. Press the down arrow 
 to select  Restore defaults , and then press OK .

							Interpret control-panel messages
The control-panel messages indicate the current product status or situations that might require action.
Control-panel messages appear temporarily and might require that you acknowledge the message by
pressing OK to resume printing or by pressing  X to cancel the job. With certain messages, the job might
not finish printing or the print quality might be affected. If the message is related to printing and the auto-
continue feature is on, the product will attempt to resume printing after the message has appeared for
10 seconds without acknowledgement.
For some messages, restarting the product might fix the problem. If a critical error persists, the product
might require service.

							Jams
Common causes of jams
Many jams are caused by using paper that does not meet HP specifications. 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 .
The product is jammed.1
CauseSolution
The paper does not meet specifications.Use only paper that meets HP specifications. See Paper andprint media on page 43.
A component is installed incorrectly.Verify that the print cartridge is correctly installed.
You are using paper that has already passed through a product
or copier.Do not use paper that has been pr eviously printed on or copied.
A tray is loaded incorrectly.Remove any excess paper from the tray. Make sure that the
stack is below the maximum stack height mark in the tray. See
Load trays on page 50.
The paper is skewed.The tray guides are not adjusted correctly. Adjust them so they
hold the stack firmly in place without bending it.
The paper is binding or sticking together.Remove the paper, flex it, rotate it 180°, or flip it over. Reload
the paper into the tray.
NOTE:Do not fan paper. Fanning can create static
electricity, which can cause paper to stick together.
The paper is removed before it settles into the output bin.Reset the product. Wait until the page completely settles in the
output bin before removing it.
During two-sided printing, you removed the paper before the
second side of the document was printed.Reset the product and print the document again. Wait until the
page completely settles in the output bin before removing it.
The paper is in poor condition.Replace the paper.
The internal rollers from the tray are not picking up the paper.Remove the top sheet of paper. If the paper is too heavy, it
might not be picked from the tray.
The paper has rough or jagged edges.Replace the paper.
The paper is perforated or embossed.Perforated or embossed paper does not separate easily. Feed
single sheets from Tray 1.
Product supply items have reached the end of their useful life.Check the product control panel for messages prompting you
to replace supplies, or print a supplies status page to verify the
remaining life of the supplies. See 
Print the informationpages on page 70.
Paper was not stored correctly. Replace the paper in the trays. Paper should be stored in the
original packaging in a controlled environment.
