Just a word of caution: if you have a new printer under warranty, be sure to use all inks that are are still fresh, meaning not expired.
Official word from HP is:
"...On the box is the sell by/ expiration date. Somewhere in very small print
on the printhead is either the expire date or manufacture date. If it's the
manufacture date then there is no other wording on it and the printhead is
good for two years after the manufacture date. If it's the expire date it
usually starts with that "expire or install by XX/XX/XX. If the customer
has installed expired ink it does not void warranty of the whole printer
just whatever components that comes in contact with the ink. Which is ink
cart, ink tube system and prnitheads. And also any image or color quality
issues are not guaranteed until fresh ink is installed...."
Further:
"The warranty policy for ink supplies (and hence “dating” policy on the
retail boxes) can vary by product. For the HP 70 ink cartridges, the
end of warranty date, and hence the warranty policy, is set to be 30 months from the date of
manufacture. Nearly all supplies warranty and dating are based on when
the product was manufactured. This is why there can be a varying date
on these products, and why the customer sees these dates
be quite disparate. Manufacturing is done in batches, at certain times
of the month or quarter, and then they are dated 30 months out. As
they move thru the supply chain and distribution channel, they can get
intermixed and this will result in this variance in dates seen by the customer. HP does not have a “standard” window of
guarantee (or warranty), but we do try to ensure there is at least 6-12
months of “usable life” remaining (most often way more than this), once a
customer purchases the supplies..."
On our machines (Z3200 24 and 44 inch models) that are no longer under warranty, I use older inks and have no problems.
The newest machine that is under a 5 year carepack warranty - I am very careful to make sure it has all new, unexpired ink in it.
That little statement about "If the customer
has installed expired ink it does not void warranty of the whole printer
just whatever components that comes in contact with the ink. Which is ink
cart, ink tube system and prnitheads. And also any image or color quality
issues are not guaranteed until fresh ink is installed...." is a real gotcha, if they decide to enforce it.
I don't expect these issues, but be aware, it is lurking in the wings if you have a new printer.
