Title: Optical scanning method for laser beam printer
Inventor: ISHIZUKA YUTAKA
IPC: B41J2/44
Filed: 1987-04-20
Abstract: PURPOSE:To reduce variation in reflection factor by correcting the variation in reflection factor affected by variation in the angle of incidence of a laser beam on a rotary polygon mirror in rotation. CONSTITUTION:The oscillation frequency of a laser oscillator 10 itself is made optionally controllable and then the influence of the variation in the angle of incidence of the beam on the rotary polygon mirror on the reflection factor is corrected. Namely, the reflection factor of the rotary polygon mirror 4 has characteristics which vary with the wavelength of the laser beam when the angle of beam incidence is made constant. The incidence angle of the incident laser beam B, therefore, varies as the rotary polygon mirror 4 rotates, and consequently even if the reflection factor of the rotary polygon mirror 4 varies, the frequency of the laser beam B is controlled by the laser oscillator 10 to minimize the variation in the reflection factor. Consequently, a latent image of high quality which has small light-shade variation is formed on a photosensitive drum to obtain a produced image with uniform density.

IPC: C09D11/02
Filed: 1993-03-30
Abstract: PURPOSE:To achieve complete recycling of cleaning liquid waste in printing by a method wherein when color is changed or printing is ended, a printing unit is cleaned by using a detergent wherein glycols of a specific ratio are mixed in water, and correcting ink wherein a solvent part of a specific rate is removed from printing ink to be used initially is added to the cleaning liquid waste generated in such case. CONSTITUTION:Printing ink wherein 95-40% in total quantity of solvent of glycols and 5-60% of water are used as a solvent for a vehicle is used to carry out printing. When color is changed or printing is ended, a solvent wherein 100-40% of glycols and 0-60% of water are mixed is used to wash a printing unit, and correcting ink is added to cleaning liquid waste generated at that time, which is recycled. Ink wherein 20-60% of the solvent part is removed from the printing ink to be used as abovementioned is used as the correcting ink. Consequently, the cleaning liquid waste can be completely recycled to serve for both reduction of a printing cost and resolution of environmental problems.
