Hi, I have an HP printer that takes 364 cartridges. I bought 3 sets of ink cartridges last December - labelled 364 - that also included a black 364 XL.
I just popped them in a drawer. Then earlier this month I took out a the black one out to use - it was the wrong size !!
Instead of 16mm across the spine of the ink it was 24mm. (both measurements approx)
I'm enclosing pics. The smaller one is the real 364 XL - the larger one is the mystery ink.
Does anyone have an idea what it is please?
Then I can offer them on my local free ads.
