The PRINTHEAD is eithere electrically damaged or is unseated (incorrectly installed or it has slipped out of position). Attempt to
print the SELF TEST or PRINT QUALITY REPORT (under TOOLS menu) to
aid in identifying which color is causing the issue. Check that cartridge or
cartridges to ensure they have plenty of ink inside.
NOTE: If one or more the colors were previously dry
fired during printing (i.e. if you continued printing using only a few colors
to one, air may have been accidently ingested into the ink lines between the
cartridge(s) and PRINTHEAD. To recover from this more severe condition,
you may have to run the CLEAN PRINTHEAD
procedure 2 or 3 times. Print the SELF TEST REPORT or PRINT QUALITY REPORT
to see if there is any visible improvement in colors and/or print quality.
If a problem persists then it is suggested to
review the steps outlined on the following Inkjet411 HP564 support page,
including printhead removal/printer electrical
contact cleaning and service station cleaning. A dirty service station can
cause poor image quality and/or ink cross-contamination between different
colors:

If the problem still cannot be corrected,
then the PRINTHEAD may be dry and may need
to be flushed (i.e. with warm water as it could have dried out, but this is
a function of how much you print). Remove
and thoroughly flush all ink ports for 2-3 minutes...thoroughly dry printhead
prior to re-installing. Retest. For complete instructions refer to video here:

Worst case scenario the PRINTHEAD may simply be electrically
damaged or at end-of-life (while rated for 10-12,000 pages, the average
consumer may only see an average of 5,000 printed page throughput) and may
require replacement. A severe failure of the PRINTHEAD is typically accompanied
by error messages such as INCOMPATIBLE PRINTHEAD, REPLACE PRINTHEAD or INK
SYSTEM FAILURE. NOTE: The PRINTHEAD will
eventually fail in time. For more information on the how the PRINTHEAD works,
watch the video here:
