CLEANING BLADE
The cleaning pressure mechanism is shown above. When the cleaning solenoid [A] is energized, it turns the cleaning solenoid lever [B] clockwise (rear view). Due to the pull of the cleaning blade pressure spring [C], the pressure arm [D] also turns clockwise and pushes the cleaning blade lever [E] up. The cleaning blade holder then rotates and the cleaning blade [F] presses against the drum. The pressure spring limits the blade pressure. The cleaning blade is mounted by a single swivel screw [G] at its exact center of gravity. With this type of mounting the blade sets parallel and applies even pressure automatically, Also since pressure is transmitted in the center, a single pressure spring is used. Side-to-side movement is applied to the cleaning blade to prevent uneven wear and ensure efficient cleaning. The blade scraper [H] is mounted in contact with the bottom of the cleaning blade. When pressure is applied to the cleaning blade, it is forced forward and bends at its outer edge. When pressure is released from the blade, it snaps back to its original shape. At this time, the blade scraper [H] scrapes off the excess toner and paper dust from the edge of the blade. This helps to maintain efficient cleaning. The blade pressure is released when there is no key input for 15 minutes, when a paper misfeed occurs, or when the safety switches are open. The blade scraper also prevents toner from scattering inside the copier by keeping toner inside the cleaning unit.
