1. Configuration
The EP-52 cartridge consists of a photosensitive drum, a primary charging roller, a developing
unit, a cleaning unit, etc.
While the photosensitive drum rotates in the cartridge, a visible image is formed on its sur-
face based on the print data according to the print process.
The cartridge has been designed in such a way that it cannot be disassembled.

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