1. Configuration
The EP-W cartridge is comprised of the photosensitive drum, primary charging roller, developing
unit, cleaning unit, etc.
While the photosensitive drum rotates within the cartridge, a visible image is formed on its
surface based on print data according to the print process.
The EP-W cartridge has been designed in such a way that it cannot be disassembled.

a. Drum Protective Shutter
Since blank spots and black lines can appear on prints as a result of strong light striking the
photosensitive drum, it is covered by a protective shutter. Do not carelessly open the protective
shutter. (The protective shutter opens automatically when the cartridge is installed in the printer.)
