The main improvement of this technique is in eliminating “jaggies” in diagonal lines. It is most
effective when the dot map data fits the development characteristics of the printer mechanism well.
It is therefore necessary to set appropriate values in printer settings.
Note:
BiRITech is not as effective for printing a mesh pattern or gray scale. In such cases,
BiRITech must be set to OFF. (The default setting is MEDIUM.) Since the BiRITech effect
depends on the toner condition, adjusted it when the imaging cartridge is replaced or after
the imaging cartridge is used for a long time.
The following settings are available in printer settings for RITech: DARK, MEDIUM, LIGHT, OFF.
The status sheet has the following RITech test image. When the toner density of area A is almost the
same as that of area B (as shown in the figure below), the RITech setting is at its optimum setting. In
other words, the optimum setting is achieved when it is difficult to distinguish the shape of area A
from that of B.
