Definitions
- a surface of the ink reservoir forms the outer closure of the ink channels towards the fourth side, which is open on the chip side. Since the chip is held non-positively on the ink reservoir only by the mounting bracket, the channel walls are movable on the surface of the ink reservoir. This disadvantage is exacerbated by the large length-thickness ratio of the order of 50: 1 and height-thickness ratio of 10: 1 of the channel partition walls.
- the end plate has openings at the intersection of the supply channels in the ink reservoir with the ink channels in the chip.
- the end plate 1 consists of a metal foil which is anodically bonded to the chip 11.
