HP 2820 - Manual (Page 258)

Problem Cause Solution
Only black is printing when the
document should be printing in
color. Color mode is not selected in
your program or printer driver. Select color mode instead of
grayscale mode.
The correct printer driver might
not be selected in the program. Select the correct printer driver.
The device might not be
correctly configured. Print a Configuration page. If
no color appears on the
Configuration page, contact
HP Customer Care. See
Service and support or the
support flyer that came in the
device box.
One or more colors are not
printing, or are inaccurate.
Sealing tape might be on the
print cartridges. Verify that the sealing tape has
been completely removed from
the print cartridges.
The media might not meet
HP specifications. Use a different paper, such as
high-quality paper that is
intended for color laser
printers. See
Media
specifications .
The device might be operating
in excessively humid conditions. Verify that the device
environment is within humidity
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 a
print cartridge .
A color is printing inconsistently
after you load a new print
cartridge. Another print cartridge might be
low. If you are using a non-
HP print cartridge, it might be
low or empty but you will
receive no indication. Check the control-panel display
or HP Toolbox to see if a print
cartridge is low, and replace it if
necessary.
Print cartridges might be
incorrectly installed. Remove the print cartridge for
the color that is printing
inconsistently and reinstall it.
