Abstract

Presented is a new adjustment method of laser beam (LB) printer for improving the quality of the printed material. For the correct adjustment of the LB-printer, the quality of characters, figures and lines can be tested without using a micro-densitometer when a new evaluation pattern is printed on a sheet of paper. The quality of the printed material is determined depending on whether the elemental dots or lines are printed in a correct size or not. Since this new evaluation pattern is used to evaluate the quality of characters, figures and lines in five steps, the line width printed on a sheet of paper is expanded or shrunken with an expansion ratio of +20%, +10%, 0%, -10% or -20% of the normal size of the elemental dots. This new evaluation pattern can be used to check if the printer is operating normally
