HP
cartridges are easy to refill, given the right tools and the appropriate
inks. Here the right tools include a quick, reliable, repeatable and
effective system to create the vacuum (also referred to as ‘negative
pressure’) required by single color HP cartridges for their operation. HP
cartridges belong to the category where the printhead is part the cartridge
itself. Some black cartridges contain a metal bellow that gradually expands
when ink is injected and gradually contracts as the ink is consumed during
printing.
Pressure on the other side of the
bellows regulates the dispensation of the ink. The refill kit includes a
quick cartridge-snap-in tool making it easy (not to say fun) to create the
vacuum and, voila’ (as they say in France) you have a cartridge as good as
new.
HP cartridges are remanufactured industrially and the process is identical to that employed by the refill kit. This should reassure some or all of the (understandably) doubting Thomases who believe that some arcane trick or consummate skill may be required to refill jet cartridges.
One word of advice given here, as well as in the instructions, is not to run printhead-host cartridges (such as the HPs) completely dry before refilling. This has to do with heat. The drier the cartridge the hotter the metal electrodes which are part of the printhead. Excessive heat tends to damage the electrodes. The electrodes carry the current that heats the air that creates the bubble that pushes the ink that forms a droplet that reaches the paper
you wanted to print on. Faulty electrode pairs break the chain.
HP
color cartridges also contain their own printhead and rely on the sponge
ink-retaining reservoir system. The refill kit also contains a ‘top-popper’
with which you literally pop open the top cover of the cartridge so as to
access the (3) fill holes.
As with all kits we
include the most recent and updated collection of tips and good-to-know
information gathered from our users. Still uncertain? Do not let "the
native hue of resolution be sicklied over by the pale cast of thought"
(Hamlet). Charge on and recharge your own cartridges!
