The packaging looks rather a bit tiny and you think first: As should be 10 pieces in it?
But they were then. However, unlike HP cartridges, they are really small.
But first installed printer and not the original cartridges but these are used here.
Unfortunately drooling at opening the shutter a bit, so please carefully open and what lay ready for wiping.
The incorporation into the printer is easy and is immediately recognized by the printer, even with level indicator.
The level indicator is somewhat tricky.
The cartridge is "split in two" in the room is a half ink, in the other a kind of sponge that absorbs the ink and write to mice.
The level indicator is, however, integrated into the ink supply, that is, when the ink is running low. And you can print 1-2 days not then the ink moves into the sponge and the display says empty.
However, you can then press OK 1-2 times the printer print anyway. (With me 60 pages went problemslos only with ink in the sponge)
So be careful because you can still bring some out.
!!! However, one should "make empty" while watching since this possibly the printhead may be damaged. (See comment) !!!
The capacity of a large black cartridge is about 500 pages, the others are (fortunately) not yet empty.
The cartridges I can recommend in good conscience.
But for frequent printers I recommend anyway to use refillable cartridges. (I will now do)
Although these cartridges are really cheap, but bothers me the "sponge" problem which is still quite a bit of ink remaining in the sponge remains. And thus the ink level indicator is also something "spongy".
