CHAPTER 3 2. Photosensitive drum As a general rule, do not touch the photosensitive drum with your hand nor clean it. However, if it becomes necessary to clean it, do so in the following way. 1) Open the upper cover to remove the EP- W cartridge. 2) Open the protective shutter. 3) Apply toner to a flannel cloth and clean the dirty drum surface. Notes: 1. Rotate the drum in the same direction that it rotates during printing. Do not rotate the drum in the opposite direction as the connection of the plate spring that applies developing bias to the developing cylinder will be damaged. Do not touch the photosensitive section of the drum. 2. Do not use lint-free paper as it will scratch the drum. Do not use solvents when cleaning. 3. Clean the drum quickly as lengthy exposure to light can have adverse effects on print images. B. Transfer Charging Roller 1. Removal from the printer 1) Open the upper cover. 2) Open the transfer charging roller guide. 3) Pinch the gear, lift it slightly, and slide it to the left.
