							Printing on both sides (duplexing)
You can print on both sides of a sheet of media, either automatically by using the optional automatic
two-sided printing accessory (duplex unit), or manually by turning the media over and feeding it into
the printer again.
Guidelines for printing on both sides of a page
●Always use media that conforms to the printer specifications. See Understanding specifications
for supported media.
●Specify duplex options in your application or in the printer driver.
●Do not print on both sides of transparencies, envelopes, photo paper, glossy media, or paper
lighter than 16 lb bond (60 g/m
2) or heavier than 28 lb bond (105 g/m2). Jams might occur with
these media types.
●Several kinds of media require a specific orientation when you print on both sides of a page,
such as letterhead, preprinted paper, and paper with watermarks and prepunched holes. When
you print from a computer running Windows, the printer prints the first side of the media first.
When you print from a computer using the Mac OS, the printer prints the second side first. Load
the media with the front side facing down.
●For auto-duplexing, when printing finishes on one side of the media, the printer holds the media
and pauses while the ink dries. Once the ink dries, the media is pulled back into the printer and
the second side is printed. When printing is complete, the media is dropped onto the output tray.
Do not grab it before printing is complete.
●You can print on both sides of supported custom-sized media by using the printers manual
duplex capabilities. For a list of supported custom-sized media, see 
Understanding specifications
for supported media.

							Replacing the ink cartridges
You can check the estimated ink levels from the Toolbox (Windows), the HP Printer Utility (Mac OS),
or the embedded Web server. For information about using these tools, see 
Overview of printer
management tools. You can also print the configuration page to view this information (see
Understanding the configuration page).
NOTEAfter removing a cartridge from its package, install it right away. Do not remove a
cartridge from the printer for long periods of time.
To find out which ink cartridges work with your printer, see 
Supplies.
To replace the ink cartridges
1.Gently pull open the ink cartridge cover.
2.Remove the ink cartridge that requires replacement by grasping it between your thumb and
forefinger and pulling it firmly toward you.
3.Remove the new ink cartridge from its package.
4.Align the cartridge with its color-coded slot and insert the cartridge into the slot. Press down
firmly on the cartridge to ensure proper contact.
5.Close the ink cartridge cover.

							Maintaining the printheads
If printed characters are incomplete, or dots or lines are missing from printouts, this may be caused
by clogged ink nozzles and you might need to clean the printheads.
When the quality of printouts deteriorates, complete the relevant steps based on the following
sequence:
1.Check the health of the printheads (see 
To check printhead health).
2.Print the print quality diagnostic page on a clean sheet of white paper. Evaluate any problem
areas, and perform the recommended actions (see 
To print the print quality diagnostic page).
3.If the color tints on printed pages have shifted visibly towards yellow, magenta, or blue, calibrate
the color (see 
Calibrating the color).
4.Manually clean the printhead contacts. See 
To clean the printhead contacts manually.
5.Replace the printheads, if the problems persist after cleaning. See 
To replace the printheads.
CAUTIONHP is not responsible for damage to the printer that results from modifying the
printheads.
To check printhead health
Use one of the following means to check the printhead health. If the status of any printhead is not
good or fair, then perform one or more of the maintenance functions, or clean or replace the printhead.
●Configuration page: Print the configuration page on a clean sheet of white paper, and check
the printhead health section. See 
Understanding the configuration page.
●Embedded Web server: Open the embedded Web server (see 
To open the embedded Web
server). Click the Information tab and click Ink Supplies in the left pane.
●Toolbox (Windows): Open the Toolbox (see 
To open the Toolbox). Click the Information tab
and click Printhead Health.
To print the print quality diagnostic page
Use the print quality diagnostic page to diagnose issues affecting the print quality of the printer. This
will help you decide whether to run any maintenance tools to improve the print quality of your
printouts. You can also view the ink level information, and the printhead health status on the page.
●
Control panel: Press and hold 
 (Power button), press  (Cancel button) once, press
