摘要： An apparatus includes an inkjet assembly having inkjet nozzles through each of which ink flows at a nominal flow rate as it is ejected from the nozzle onto a substrate. Ink is held under a nominal negative pressure associated with a characteristic of a meniscus of the ink in the nozzle when ejection of ink from the nozzle is not occurring. The apparatus includes recirculation flow paths, each flow path having a nozzle end at which it opens into one of the nozzles and another location spaced from the nozzle end that is to be subjected to a recirculation pressure lower than the nominal negative pressure so that ink is recirculated from the nozzle through the flow path at a recirculation flow rate. Each recirculation flow path has a fluidic resistance between the nozzle end and the other location such that a recirculation pressure at the nozzle end of the flow path that results from the recirculation pressure applied at the other location of the flow path is small enough so that any reduction in flow rate below the nominal flow rate when ink is being ejected is less than a threshold, or a change in the nominal negative pressure when ink is not being ejected is less than a threshold, or both.

摘要： A thermal ink jet recording apparatus includes an ink film (21) having a plurality of apertures (22) for retaining ink and movable along a path in the form of a loop, the ink film having an electrical resistance material (35) extending in a direction perpendicular to the path. A thermal head (3) contacts one of opposite surface of the ink film for applying heat to it corresponding to a pattern to be printed. An ink container (26) is located on the path upstream of the thermal head (3) and contains solid ink which melts when heated, and a device is provided for applying a voltage across the edges of the ink film. In this manner, the heated ink film causes the ink to melt thereby filing apertures (22). The ink film (21) has first and second opposite surfaces. In the first embodiment, the first surface and opposite edge portions of the ink film on both surfaces have an electrical resistance layer (35) while the remaining portions of the second surface have an insulating layer (34). In another embodiment, stripe-like electrical resistance layers (37a, 37b, 37c) are provided on the first surface and on opposite edge portions of the second surface. Finally, in another embodiment, electrical resistance layers (39a, 39b, 39c) are provided on the first surface and on opposite edge portion of the second surface, the resistance layers on the second surface being displaced relative to the electrical resistance layers on the first surface.
