 |
|
My HP D7360 printer had to be replaced under warranty. The HP lady who
authorised the replacement took pains to tell me to remove *all*
accessories, including the cartridges, from the old printer before
sending it back. So that's what I did. However...
The new printer came with carts installed, and a generic note saying
something like "use only the new new carts in the exchange unit, the ink
is specially formulated to mix-up with the one in the printhead assembly
at first-time setup." The implication being that using the old carts in
the new unit can cause damage.
What is the actual situation please?

The ink in the heads of returned printers may be dried out or non-OEM
(assuming the printhead is not integral with the cartridge). If refurb.
does not involve replacing the head, they may provide an installed
cartridge formulated with a solvent to clear any residue of non-OEM
ink in the head.
In any event it's been my experience that removing and replacing
cartridges can damage the seal so ink gets distributed around
inside the printer, I suspect that some cartridge piercing spikes
are fir tree in shape, and tend to pull the seal out of shape as the
cartridge is removed, as a way to discourage refilling. |

It is not a matter of damage. The printheads initially have a different
dye load than "standard" cartridges, the special first-time cartridges
have yet another dye load formulated to give the right mixture when used
with the new printheads. Once this first cartridge is used you can use
the the normal cartridges.
