2.2.2 Principles of the Printing Operation

The printing mechanism of this printer uses a drop-on-demand ink jet system similar to the system used on all
other EPSON ink jet printers. However, the printhead in this system is completely redesigned to make it more
compact and ensure a high level of reliability, just as with the Stylus Color. The figure below shows the
structure of the printhead and ink supply system.
