Image Cartridge

Installat ion

1. Open the top front cover.

2. Hold the cartridge handle and pull it out while lifting it up toward outside.

3. Remove the cartridge wrapping.

Cartridge handle

Do not touch the cartridge’s bottom drum with bare hands.

4. Hold cartridge handles and shake it lightly to spread toner evenly.

5. Hold cartridge handles and place the both cartridge hooks with the printer holes.

6. Push the cartridge in until it clicks and locks.

7. Close the front cover. Check if both ends of cover clicked and locked.

Check if multipurpose tray’s cover is closed when closing the front cover. If the front cover is closed while multipurpose tray’s cover is open, it can cause paper jam and malfunction.

Detailed Description

IMAGE PROCESS

Electrification

Voltage of -1650V is applied to electrification roller from HVPS and the drum surface gets electrification of 1100V.

Exposure

Laser scanning is performed to the image printing area and the surface electric potent ial of scanned area drops to about -300V to form ‘Latent Image’.

Development

Images are formed on the drum surface by attaching the electrificat ion toner with about -600V via development roller and Doctor blade on the latent image area formed by laser from exposure stage.

Transfer

Images are formed by tonner transfer on the drum surface from the Development stage and when paper passes, about over +2000V electric potential applied transfer roller pulls the image forming toner particles on drum surface to form unsettled images on the paper.

Cleaning

Remaining toner on the drum surface after transferred to paper gets trimmed by cleaning blade before getting into electrificat ion roller and gets collected in the used toner collecting space.

Main Driving Gear Units

Main Driving Gear Unit Components

The machine has one main motor and the rotation of this motor is delivered to the train of gears composed with various gears to operate developer/drum, bypass tray, Fusing unit, duplex unit, Registration roller and pickup roller.

Operate Multipurpose Tray

When machine’s front door is opened, the link connected to the front door moves to the posit ion 1. The guide lever rotates as 2 by moving link and pulls coupler to 3 direction on the rail to disconnect from image cartridge.

2, Closing Front Cover

When closing the front door, the link connected to the front door moves to the position 1 and the connected guide lever rotates to 2 direction. When the guide lever rotates and goes down on the rail, the coupler returns to 3 direction by spring and connects with image cartridge.

Removing Fusing Unit Paper Jam

1. Removing paper on the back of Fusing unit

The gear link gets pushed back and disconnects gear connection and allows it to remove jammed paper.

2. Removing paper on the front of Fusing unit

When front door is opened, gears are disconnected by the link connected with front door and allow it to remove paper easily.
