Title: Ink jet recorder
Inventor: FUKUSHIMA HISASHI
IPC: B41J2/01
Filed: 1990-02-13
Abstract: PURPOSE:To prevent dispersion of discharge for each discharge opening by a method wherein discharge of ink to be discharged from a plurality of discharge openings is detected, and an electric signal to be given to a recording head is corrected according to said result. CONSTITUTION:Discharge opening (a) to (d) are filled with ink of specific condition common thereto (approx. 3cp in viscosity), and drive of specific pulse widths (4.5mus, 5.0mus,...7.0mus) is performed at specific voltage (approx. 25V). In that case, a difference appears according to a discharge characteristic of each discharge opening. The discharge opening (a) requires the maximum energy for discharge, and energy of the discharge opening (d) is the minimum among four discharge openings. Then, when ink viscosity is 3cp, ink is discharged for voltage impressing time of 5.0mus or longer with the discharge opening (d) and is discharged for voltage impressing time of 6.5mus or longer with the discharge opening (a). Such a difference in a discharge characteristic of each discharge opening is detected, and a drive condition is varied independently for each heating element corresponding to each discharge opening according to said detection result. For actual algorithm, the pulse width is increased by 0.5mus from 4.5mus to 7.0mus, the discharge opening being classified for each pulse width which starts discharging, and a suitable pulse width is established for each discharge opening group.
