1. Make sure that the print cartridge is fully installed.
2. The toner level in the print cartridge might be low. Replace the print cartridge.
3. The media might not meet HP specifications (for example, the paper is too moist or too
rough). See 
Paper specifications .

1. Make sure that the print cartridge is fully installed.
2. Make sure that the EconoMode setting is turned  off at the control panel and in the printer
driver.
3. Open the Configure Device menu at the printer control panel. Open the Print Quality submenu and increase the TONER DENSITY setting. See 
Print Quality submenu .
4. Try using a different type of paper.

2. If the paper is rough, and the toner  easily rubs off, open the Configure Device menu at
the printer control panel. Open the Print Quality submenu, select  FUSER MODES, and
then select the paper type you are using.  Change the setting to HIGH 1 or HIGH 2,
which helps the toner fuse more completely onto the paper. (See 
Print Quality submenu .)
3. Try using a smoother paper.

Loading trays.) Make sure that the guides in the  tray are not too tight or too loose
against the paper.
4. Turn over the stack of paper in  the tray. Also, try rotating the paper 180°.

5. If paper is lightweight and smooth, open  the Configure Device menu at the printer
control panel. On the Print Quality submenu, select  FUSER MODES, and then select the
paper type you are using. Change the setting to  LOW, which helps reduce the heat in
the fusing process. (See 
Print Quality submenu .) You must also set the type of paper for
the tray you are using. (See 
Printing by type and size of media (locking trays) .)

This defect typically occurs when the print cartridge has far exceeded its rated life of 6,000
(Q6511A) or 12,000 (Q6511X) pages. For example, if you are printing a very large quantity
of pages with very little toner coverage.
1. Replace the print cartridge.

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 application, rotate the whole page 180° to print the lighter image first.
● If the defect occurs later in a print job, turn  the printer power off for 10 minutes, and then
turn the printer power on to restart the print job.

							Troubleshooting network printing problems
NOTEHP recommends that you use the printer CD-ROM to install and set up the printer on a
network.
● Print a configuration page (see 
Configuration page ). If an HP Jetdirect print server is
installed, printing a configuration page also prints a second page that shows the network
settings and status.
● See the  HP Jetdirect Print Server Administrators Guide  on the printer CD-ROM for
help and for more information about the Jetdirect configuration page. To reach the
guide, select the appropriate print server series, select the appropriate print server
product, and then click  troubleshoot a problem .
● Try printing the job from another computer.
● To verify that a printer works with a computer,  use a parallel or USB cable to connect it
directly to a computer. You will have to reinstall the printing software. Print a document
from a program that has printed correctly in the past. If this works, a problem with the
network might exist.
● Contact your network administrator for assistance.
