Operating Principles
3. Normal Dot / EPSON Micro Dot Printing Modes
The Stylus 1500 uses two ink ejection modes (normal dot and EPSON Micro Dot) for monochrome ink
printing.
In normal dot printing mode, the print dot consists of two ink dots combined into a single dot. Since this
mode uses a larger dot size, the space between dots becomes narrower.
In EPSON Micro Dot Printing Mode, the print dot consists of only one ink dot, so a smaller dot is used. This
mode is therefore useful for a larger graded representation and for preventing white banding. Micro Dot
mode can be used for EPSON exclusive paper or transparencies with the appropriate paper settings. This
mode can also be selected for normal paper printing in super fine (720 dpi) quality.
