If you have the tri-color and photo print cartridges installed, try calibrating 
the color. For instructions, see Calibrating color.
Colors are printing as black and white
Check the printer driver settings

For Windows, the Print In Gray scale check box is probably selected. From 
your software application, open the Printer Properties dialog box. Click 
the Color tab and make sure Print in Gray scale is not selected.
For Macintosh, open the Print dialog box and from the Image panel, make 
sure that Gray scale is not selected.

If you are printing with only the black or photo print cartridge, the printout 
will be printed in grayscale. See Single-cartridge printing mode.
Wrong colors are printing
Check the printer driver settings

For Windows, the Print In Gray scale check box might be selected. From 
your software application, open the Printer Properties dialog box. Click 
the Color tab and make sure Print in Gray scale is not selected.
For Macintosh, open the Print dialog box and from the Image panel, make 
sure that Gray scale is not selected.

For Windows, try adjusting the Saturation, Brightness and Color Tone 
from the Color tab in the printer driver. For Macintosh, adjust these 
settings from the Color Panel in the Print dialog box.
Check the print cartridges

When colors are completely wrong, the printer might have run out of one or 
more colors of ink. Check the print cartridge LEDs to make sure they are 
not on (see LED Reference). You can also check the status of the print 
cartridges from the Printer Status tab in the Toolbox. Replace any low or 
empty print cartridges. For instructions, see Replacing the print cartridges.

If you are printing with only one print cartridge, see Single-cartridge printing 
mode.

If you have the tri-color and photo print cartridges installed, and the color 
does not print out as expected or there is a color tinge in gray shades, try 
calibrating the color. For instructions, see Calibrating color.

Whenever print quality noticeably decreases, try cleaning the print 
cartridges. For instructions, see Cleaning the print cartridges.

Bleeding colors in printout
If the ink is spreading on the page or colors are blending together, try the 
following:
Check the print settings

Some paper type settings (such as Transparency  Films and Photo 
Papers) and print quality settings (such as Best) require more ink than 
others. Choose different print settings in the printer driver. Also, make sure 
that you have selected the correct media type in the printer driver. 
Selecting the wrong media type causes the wrong amount of ink to be used 
on the media.

Check that the media is printed on the print side.
Check the print cartridges

Make sure the print cartridges have not been tampered with. Refilling 
processes and the use of incompatible inks can disrupt the intricate printing 
system and result in reduced print quality and damage to the printer. HP 
does not guarantee or support refilled print cartridges.
For information on ordering HP accessories, see HP Supplies and 
Accessories.

The print cartridges need to be aligned when a print cartridge is replaced. 
You can align the print cartridges from the printer driver or the Toolbox. For 
instructions, see Aligning the print cartridges.
Colors do not line up properly
Check the print cartridges

The print cartridges need to be aligned when a print cartridge is replaced. 
You can align the print cartridges from the printer driver or the Toolbox. For 
instructions, see Aligning the print cartridges.
Check the graphics placement

Use the zoom or print preview feature of your software to check for gaps in 
the placement of graphics on the page.
If printing using a single print cartridge
If one of your print cartridges runs out of ink before you can replace it, you 
can still print with a single print cartridge.
Printing with one print cartridge may be slower, and colors will differ from 
those when both print cartridges are installed. It is recommended to install 
both print cartridges. For more information, see Single-cartridge printing 
mode.

Wireless printing problems
Infrared printing does not work
Check for obstacles
Clear any obstacles between the printer and the device from which you are 
sending the print job. Sunlight, heat from nearby equipment, or other 
sources of infrared radiation can also cause transmission errors.
Move closer to the printer
Make sure the device is no more than three feet (one meter) from the 
printer when you send the print job, and that the ports face each other as 
squarely as possible.
Send the print job again
There may be a loss of data; try sending the print job again.
Check software
Make sure any necessary software is installed in the host device, for 
example, BtPrint for Palm OS PDA users. If you are still having problems, 
consult the documentation for the PDA or notebook computer.
Bluetooth printing does not work
Check the wireless settings
From the Toolbox, click the Printer Services tab and then click the 
Configure Bluetooth Settings button. Make sure your Bluetooth settings 
are correct. Also see Bluetooth printing.
Send the print job again
There may be a loss of data; try sending the print job again.
Check the software

Solving media feed problems
This section provides solutions to common media feed problems.
Media is not picked up from the input tray

Make sure to pull up the input tray extension.

Remove the media, fan it, and reload.

Make sure the media is squarely against the alignment guide and that the 
paper guide is snug, but not tight, against the media. For media using the 
card slot, make sure the media is aligned squarely against the right edge of 
the card slot. Adjust the paper guide on the slot until it fits snugly against 
the left edge of the media. 

Make sure the media you are using is not wrinkled, bent or curled. Uncurl 
paper by bending it in the opposite direction of the curl. Do not leave media 
in the input tray overnight. Leaving media in the input tray overnight can 
cause it to bend.

Do not load more than 45 sheets of plain paper or a stack paper more than 
0.18 in (4.5 mm) thick into the input tray. For other media input capacity, 
see Printer Specifications.
Paper skew

Make sure to fully extend the input tray extension.

Remove the media, fan, and reload.

Make sure the media is squarely against the alignment guide and that the 
paper guide is snug, but not tight, against the media. For cards, make sure 
they are aligned squarely against the right edge of the card slot. Adjust the 
paper guide on the slot until it fits snugly against the left edge of the media. 

Make sure the media you are using is not wrinkled, bent or curled. Uncurl 
paper by bending it in the opposite direction of the curl. Do not leave media 
in the input tray overnight. This can cause it to bend.
Paper output problem
Remove excess media from the output area. If printed media stacks up 
outside the output slot, it may prevent media from properly exiting the 
printer.

Print media is jammed
If print media is jammed in the printer, follow these instructions to clear the jam.
1Turn off the printer.
2Remove media that is not jammed from the input tray and the output slot.
3Locate the media jam.
4If the media is visible from the output slot, pull it out from the slot. 
Otherwise, open the front access cover and clear jammed media.
5If the print carriage is obstructing the jam, gently push it to one side and 
then remove the media.
6If the jammed media is not visible in the print area located inside the 
printer, remove what is visible in the input tray.
7After you clear the jam, close the front access cover, turn on the printer, 
and then press the 
RESUME BUTTON to continue the print job.
The printer will continue the print job on the next page. You will need to 
resend the page or pages that were jammed in the printer. Do not stick your hands in the input tray. Use tweezers instead and be careful 
not to scratch the inside of the printer.
Remove jammed media slowly and steadily to prevent media tear.

Tips for avoiding paper jams

Make sure nothing is blocking the paper path.

Do not overload the input tray or the card slot. The input tray holds up to 
45 sheets of plain paper or other print media measuring 0.18 in (4.5 mm) in 
thickness.

Load paper properly, making sure the paper is squarely against the 
alignment guide and that the paper guide is snug, but not tight, against the 
paper. For cards, make sure they are aligned squarely against the right 
edge of the card slot. Adjust the paper guide on the slot until it fits snugly 
against the left edge of the media. 

Do not use paper that is curled or crumpled.

Always use paper that conforms with the media types/sizes and media 
weights listed in Printer Specifications. See HP Supplies and Accessories 
for a list of HP-recommended media.

Always stack paper neatly when printing on both sides of the page 
(two-sided printing).
