HP Ink

[kers]

Why are the numbers here in the 1000's but the ones from Ker all in under 20ish? Are we looking at a different unit of measurement (assume)?

because i noted the relative usage

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.

Thanks Mark.

Printer has officially landed in my living room but not unpacked yet. Once I unpack I will check the dates as described.

WOW now that is what I call a real tip :-)

Indeed it is. Cuts the cost of ink for me by half. Ernst recommends this procedure, too.

I wonder what happens if you let a 300ml cart run right to empty.  When my starter carts ran out, the printer stopped, I installed new ones and away it went again.  Invisible on print.

Well I actually tried this 772 cart method first, after refilling the 70 carts with the even larger carts 750ml of the Z6200. Refilling carts is more risky as it is almost impossible to avoid some air in the ink bags and I fear then the printer hardware/firmware/sensors may not work correctly on the empty stage of the cart. The 772 cart method is more convenient. I only use them on the fast consumed inks and still buy from time to time a 70 cart to get a fresh chip for the next 772 round.

I haven't seen any issues with expired ink on my Z5200 other than a control panel warning that a cartridge is expired.

My printer says that the yellow cart has "expired".  I don't see any way to recover back to the "ready" status so that I can continue printing.  I pulled the cart and it's not empty.

How should I proceed?
