For poor printing problems I suggest you run the Tap 10 diagnostic print test (see link to video below). If the new (or
refilled/reman/compatible) HP 56, 57 or 58 ink cartridge refuses to print
black/color and/or function at all (i.e. blinking ink light on Deskjet 5000
series printer) or fails to complete the printer alignment following cartridge
installation, then the ink cartridge either has a connectivity issue with the
flexible printed circuit cable (inside unit where cartridge mates with cable),
the rear cartridge contacts or cable contacts are dirty with ink residue, or
the cartridge is suffering from marginal internal electrical performance. It is
suggested you perform the TAP 43 (and TAP 10) DIAGNOSTIC PRINTER TEST to
evaluate the ink cartridges electrical performance. Visit Inkjet411 support
site to see instructional video:

NOTE: For the HP Deskjet
5000 series printer models, when you get an HP 56, 57 or 58 integrated ink
cartridge refilled (i.e. currently offered at Costco or Frys today) or if you
buy a remanufactured/compatible HP ink cartridge, the ink levels are not
initially reset. However, continuing to use an ink cartridge which displays LOW
INK alerts is permitted by the printer, simply select OK, CONTINUE or DISMISS
when these alerts are observed. Now, it is possible to reset the ink levels by
performing the procedure outlined on Inkjet411's site:

To clean the HP 56, 57 or
58 ink cartridges please visit the Inkjet411 site which provides
recommendations on how to clean the electrical contacts, flex driver cables and
how to perform a hot water flush of the nozzle plate (refer to video):
