Ricoh 3131 Betriebsanweisung

Generally, printers use 4 color toners or inks (3 primary colors and black) which are mixed

together to reproduce colors. (In theory, any color can be made with the 3 primary colors, but

black is difficult to reproduce since the 3 primary colors may make it dark brownish.)

This copier makes a full-color image by piling up the 4 color toners one by one on paper

conveyed on the transfer belt as shown in the figure above.
