Mono ink tank with features spaced by distances ensuring interface with printhead

An ink tank with features spaced apart by distances ensuring interface with a printhead of an inkjet printing system, comprising:

• a reservoir body with a length, a width and a height and having opposite front and rear walls, right and left walls and a bottom wall connected together at respective right and left front and rear corners, right and left bottom corners and front and rear bottom corners, and a top rim on the walls defining a top opening on said reservoir body, said width of said reservoir body extending between outer surfaces of said right and left walls being within a range of from approximately 15.8 mm to 21.5 mm;
• a top cover attached on said reservoir body so as to substantially close said top opening of said reservoir body for containing a supply of ink within at least one interior chamber of said ink tank;
• a protrusion on said front wall having an upper edge disposed adjacent to said top rim and defining a lip on said protrusion adapted to engage a latch on a printhead, the lip enabling seating of said reservoir body therein;
• at least one protuberance on said rear wall disposed adjacent to and above said rear bottom corner and diagonally across said reservoir body from said lip on said protrusion on said front wall, said protuberance adapted to insert into a slot in the printhead, the protuberance for enabling seating and releasable locking of said reservoir body therein;
• and
• at least one snout on said bottom wall disposed closer to said front wall than to said rear wall and adapted to be in fluid communication with an orifice in the printhead as said reservoir body is pivotally inserted and seated in the printhead;
• wherein a furthermost point of said protuberance is displaced from a furthermost point of said lip by a distance of no more than 78.0 mm, as measured along an axis extending substantially parallel to the length of said reservoir body;
• said protuberance having a height extending above an outer surface of said bottom wall within a range of from approximately 0.3 m to 4.6 mm, as measured along an axis extending substantially parallel to the height of said reservoir body;
• said snout having a central axis displaced from said lip of said protrusion by a distance within a range of from approximately 18.1 mm to 19.1 mm, as measured along an axis extending substantially parallel to the length of said reservoir body;
• said snout having a height extending below said outer surface of said bottom wall within a range of from approximately 1.2 mm to 3.8 mm, as measured along an axis extending substantially parallel to the height of said reservoir body
