Clearing jams
Occasionally, paper or other print media can become jammed during a print job. Some causes include
the following events:
●The input trays are loaded improperly or overfilled.
● Tray 2 or optional Tray 3 is opened during a print job.
● Too many sheets accumulated in the output area or sheets blocked the output area.
● The print media that is being used does not meet HP specifications. See 
Print-media specifications
.
● The environment in which the print media was stored is too humid or too dry. See 
Print-media
specifications
.
Where to look for jams
Jams can occur in these locations:
●Inside the printer. See 
To clear jams from inside the printer
.
● In input areas. See 
To clear jams from Tray 2 or optional Tray 3
.
● In the output area. See 
To clear jams from the top bin
.
Find and remove the jam by using the instructions on the following pages. If the location of the jam is
not obvious, first look inside the printer.
Loose toner might remain in the printer after a jam. This problem should resolve itself after a few sheets
have been printed.
Each section below corresponds to an area where a paper jam could occur. Use the following
procedures to clear the jam. In all cases, grasp the jammed paper by both corners and pull slowly to
remove the paper.

To clear jams from inside the printer
CAUTIONJams in this area might result in loose toner on the page. If you get toner on your
clothes or hands, wash them in cold water. (Hot water will set the toner into the fabric.)
1. Open the front door.
CAUTION Do not place anything on the transfer belt, which is located on the inside
of the front door. Otherwise, the printer may be damaged, adversely affecting print
quality.
2. Carefully grasp the jammed paper by both corners and pull slowly to remove the paper.

Print problems
Print quality problems
Occasionally, you might encounter problems with print quality. The information in the following sections
helps you identify and resolve these issues.
Improving print quality
Use the print-quality settings to prevent print-quality problems.
Understanding print-quality settings
Print-quality settings affect how light or dark the print is on the page and the style in which the graphics
are printed. You can also use the print-quality settings to optimize the print quality for a specific media
type.
You can change the settings in the device properties to accommodate the types of jobs that you are
printing. The following settings are available, depending on the printer driver that you are using:
●600 dpi
● Custom:
 This setting produces the same resolution as the default setting, but you can change the
scale patterns.
NOTE Changing the resolution can change the formatting of your text.
To temporarily change print-quality settings
To change the print-quality settings only for the current software program, open the properties through
the Print Setup  menu in the program that you are using to print.
To change print-quality settings for all future jobs
For Windows 98, Windows 2000, and Windows Me:
1. In the Windows system tray, click  Start, select  Settings , and then click  Printers.
2. Right-click the device icon.
3. Click  Properties  (in Windows 2000, you can also click  Printing Preferences).
4. Change the settings, and click  OK.
For Windows XP:
1. In the Windows system tray, click  Start, click  Control Panel , and then click  Printers and Faxes .
2. Right-click the device icon.
3. Click  Properties , or click Printing Preferences .
4. Change the settings, and click  OK.
Identifying and correcting print defects
Use the checklist and print-quality issues charts in this section to solve print-quality problems.
84 Chapter 8   Problem solving ENWW
 
						

							
Print-quality checklist
General print-quality problems can be solved by using the following checklist:
1.Make sure that the paper or print media that you are using meets specifications. Generally,
smoother paper provides better results.
2. If you are using a special print media such as labels, transparencies, glossy, or letterhead, ensure
that you have printed by type.
3. Print a Configuration page and Supplies Status page at the device. See 
Special pages .
● Check the Supplies Status page to see if any supplies are low or empty. No information is
provided for non-HP print cartridges.
● If the pages do not print correctly, the problem is with the hardware. Contact HP Customer
Care. See 
HP Customer Care
 or the flyer that came in the device box.
4. Print a Demo page from the HP Toolbox. If the page prints, the problem is with the printer driver.
5. Try printing from a different program. If the page  prints correctly, the problem is with the program
from which you were printing.
6. Restart the computer and the device and try printing again. If the problem is not resolved, choose
one of these options:
●If the problem is affecting all printed pages, see 
General print quality issues
.
● If the problem is affecting only pages printed in color, see 
Solving issues with color documents
.
General print quality issues
The following examples depict letter-size paper that has passed through the device short edge first.
These examples illustrate problems that would affect all of the pages that you print, whether you print
in color or in black only. The topics that follow list the typical cause and solution for each of these
examples.
ProblemCauseSolution
Print is light or faded.The media might not meet
HP specifications.Use media that meets HP specifications.
One or more print cartridges might be
low. If you are using non-HP print
cartridges, no messages appear on the
device control panel or in the
HP Toolbox.Replace any low print cartridges. See
Changing print cartridges .
If none of the print cartridges is low or
empty, remove the print cartridges one at
a time and inspect the toner roller in each
to see if the roller is damaged. If so,
replace the print cartridge.
 Print the Supplies Status page to check
the remaining life. See 
Supplies Statuspage .
Toner specks appear. The media might not meet HP
specifications.Use media that meets HP specifications.
The paper path might need cleaning. Clean the paper path. See theHP Toolbox online Help.
