HP 728 300-ml Matte Black DesignJet Ink Cartridge (F9J68A)

HP part F9J68A, the 300-milliliter Matte Black tank in HP’s 728 range — a genuine HP cartridge. Matte Black is the only black among the four 728 inks we stock.

Which printer takes it

The compatible-printer list for this cartridge names one machine: the HP DesignJet T830 MFP. If your printer came under a package name instead of an HP model number, read the family number printed on the tank you are replacing first.

What Matte Black does here

The four 728 inks we stock are Matte Black, Cyan, Magenta and Yellow, and Matte Black is the only black among them. That makes it the primary ink for text-heavy prints on plain and coated paper, which is why it tends to run down first in a print room turning out schedules, signage and announcements.

Size and cost per milliliter

The same Matte Black is also sold in a 130-milliliter tank, HP part 3WX25A. Measured per milliliter, the small tank costs about 21% more than this one, so the 300-ml tank is the cheaper ink of the two per unit while the 130-ml is the smaller single outlay. Current prices for both sit on their own product pages.

Don’t order this by mistake

These numbers do not run in sequence. F9J65A, F9J66A and F9J67A are the 130-ml Yellow, Magenta and Cyan; one digit further along, F9J68A is neither 130 ml nor a color. The small Matte Black is not adjacent to it either — that one is 3WX25A.

The full HP 728 set we stock

Four inks in two sizes, eight part numbers. At 300 ml: F9J68A Matte Black, F9K17A Cyan, F9K16A Magenta, F9K15A Yellow. At 130 ml: 3WX25A Matte Black, F9J67A Cyan, F9J66A Magenta, F9J65A Yellow. Colors and sizes sell singly, so no school has to change all four at once.

HP 728 Matte Black: what schools ask

Is Matte Black the only black in the 728 inks you stock?

The four 728 inks we stock are Matte Black, Cyan, Magenta and Yellow, so Matte Black is the only black among them and it carries the text and line work on this printer.

Should we buy the 300-ml or the 130-ml Matte Black?

On ink cost per milliliter, this one: the 130-ml 3WX25A works out about 21% more per milliliter. The 130-ml is the smaller single outlay. Current prices for both are on their product pages.

How many posters will this cartridge print?

We do not publish a figure and will not guess one — coverage, media and design move it several times over. Work from the ink remaining that the printer reports.
