PURPOSE:To obtain the high emitting reliability of ink without lowering the throughput of image output. CONSTITUTION:Pusle signals P21. P24 having a specified pulse width are usually used as the emission signals applied to the heaters of nozzles in order to emit ink liquid droplets and, when the application period of the emission signals coincides with the output period of a second timing signal, a pulse signal P23 having a large pulse width is used as an emission signal to increase the supply energy to the heaters. |
