Abstract: An apparatus and method for correcting printing characteristics of a full-line printhead, and producing a high-printing quality printhead at high manufacturing yield, a corrected printhead by this apparatus, and a printer employing this printhead. According to this method, an image is printed on a printing medium by using double pulses obtained based on fluctuation of resistance of each printing unit of a printhead, and a reference OD value is determined from an OD value histogram of the printed image. A preheating pulse width is selected, based on OD values of n printed images obtained by changing the preheating pulse width n times and the reference OD value, such that an OD value on each printing element is equal or close to the reference OD value. For example, assuming that the reference value is 0.43, a preheating pulse width on printing element No. 3 is 0.875 .mu. sec.

Abstract: PROBLEM TO BE SOLVED: To eliminate deviation in the machining dimensions and pitch of holes and trenches and occurrence of bur around an ejection opening while keeping a desired size of the holes and trenches without increasing the machining time by varying the energy density per unit time of laser light being projected to a work. SOLUTION: A work W is trenched or bored by projecting a laser light L while varying the energy density thereof per unit time. For example, a laser light L having a high energy density per unit time is employed until completion of trenching an ink channel or boring a liquid ejection opening and the energy density is lowered to a level causing no deformation of resin nor occurrence of bur immediately before completion of trenching or boring. According to the method, an ejection opening of desired size or a liquid channel of desired depth can be machined accurately.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid jet recording head in which a liquid channel and a jet port can be machined with high accuracy by evaluating the laser irradiation state and feeding back laser information and the operating rate of apparatus can be enhanced while reducing the cost. SOLUTION: When a liquid channel and a jet port are made in the resin top plate of a liquid jet recording head by laser machining, a liquid channel 23 being machined through irradiation with laser light 12 is observed and the image thereof is processed. The depth (d) of the liquid channel is measured simultaneously with machining alignment of jet port and compared with a preset standard value. Subsequently, the output state of current laser is recognized and evaluated based on the comparison results thus determining the correction quantity of laser irradiation energy for next machining. The information is fed back to a control section and a laser light source and the voltage being applied to the laser light source is regulated to emit a laser light 12 having an optimal irradiation energy density thus machining a jet port, or the like, with high accuracy.
