General Description

1.4.7 Bi Resolution Improvement Technology

The EPL-N1200 printer has BiRITech (Bi Resolution Improvement Technology), which is designed
to improve print quality at 600 DPI and 300 DPI. Using this method, dot map data extracted from the
image data and reassembled to improve print quality.
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 SelecType.

Note: BiRITech is not as effective for printing mesh patterns or gray scales. In such cases,
BiRITech must be set to OFF. (The default setting is MEDIUM.) Since the BiRITech
effect depends on the toner condition, it should be adjusted when the imaging cartridge is
replaced or after the imaging cartridge is used for a long time.
The following settings are available in SelecType Level for RITech: DARK, MEDIUM, LIGHT, OFF.
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.
