Driving circuit capable of maintaining heat equilibrium of a print head nozzle |
摘要 |
A driving circuit drives an ink jet print head in a printing device. The ink jet print head has ink jet cells and heating elements corresponding to the ink jet cells. The driving circuit has a driving signal generator that provides two different driving signals to heat the ink jet cells. The first driving signal heats cells intended for jetting ink with sufficient energy so that they do jet ink. The second driving signal heats cells not intended for jetting ink with insufficient energy so that they are heated without jetting ink.
