both PRINTHEADS will eventually fail depending on printed content, printer duty cycle (i.e. typically
rated for ~41, 500 printed pages depending on image content & frequency of printing). The average
inkjet printer can typically be refilled with ~20+ complete sets of ink cartridges over the life of the
printhead, after which, either the Yellow/Black and/or Cyan/Magenta printhead may need to be
replaced (available at HP.com). Refer to video on how the HP PRINTHEAD functions:

When the PRINTHEAD electronically fails typically the printer will provide an alert message when this
happens, but if a printhead has suffered a deprime (i.e. loss of ink/pressure which results in no printing
of color), it is possible to recover the system using a 3
rd
party PRINTHEAD priming tool, such as this one:

Regarding your recent inquiry about an HP 88 black ink cartridge error message ("MISSING OR
DAMAGED") associated with your HP 88 refilled ink cartridge, this is not the typical error message we
normally see when a refilled ink cartridge that has a correctly installed and properly programmed smart
chip. We suggest you verify that there is no ink residue on the surface of the smart chip (at rear/lower
side of ink cartridge) – refer to 4
th
picture at the following link: http://inkjet411.com/?page_id=973
It is also possible that either of the PRINTHEADs may have poor connectivity with the rear electrical
pad/interface. It is suggested that you attempt to re-seat (i.e. remove and re-install) the Yellow/Black
printhead assembly. HP.com instructions can be found here.

The inclusion of the statement "intended for single use only" is standard manufacturer language since
HP does not refill or allow customers to reuse their tanks. The ink cartridge/tank is just a plastic body
with an internal foil bag and ink port...nothing can really go bad. As long as the chip is re-programmed
(or replaced) following each use you can use it over and over again. In addition, with the HP 88s, you can
use the ink within a year following refill so there is no rush.
If you continue to see Magenta problems/errors following the chip re-programming, then this could be a
Cyan/Magenta PRINTHEAD issue (this is an electronic assembly which performs the actual 'firing' of
