Epson AcuLaser CX-11N/AcuLaser CX-11NF Field Repair Guide 9/9/05 XEROGRAPHY CONCEPTS Monochrome (Single Color) Laser Printer Image Formation Laser printers employ the Xerographic or Electrophotographic process. This process uses a laser beam to etch the image onto a light sensitive material, high voltages to move toner to the paper and heat to fuse the toner to the media. The entire process can be broken down into 7 steps.
Epson AcuLaser CX-11N/AcuLaser CX-11NF Field Repair Guide 9/9/05 Step 1: Charging/Conditioning Conditioning is the first step of laser printer image formation process. During this stage, a high negative charge is applied across the entire surface of the OPC Drum (Organic Photo Conductive) via the charging roller (see Figure 2). The surface of the OPC Drum consists of a photo conductive film material which enables it to accept and retain the negative charge.
Epson AcuLaser CX-11N/AcuLaser CX-11NF Field Repair Guide 9/9/05 Step 2: Exposure/Writing The image is etched onto the OPC Drum using a laser diode, motor driven polygonal mirror and a series of lenses and mirrors. The laser beam is deflected by the polygonal mirror, through a series of lenses and mirrors and onto the OPC Drum. The laser triggers the SOS (Start Of Scan) Sensor to indicate the start of the print line, which then signals the logic to begin transmitting the print data.
Epson AcuLaser CX-11N/AcuLaser CX-11NF Field Repair Guide 9/9/05 Step 3: Development In the development stage, the toner is transferred to the electrostatic image on the OPC Drum. The negatively charged toner on the Magnetic Roller is attracted to the less-negative latent image on the OPC Drum. The amount of toner that is attracted to the Magnetic Roller can be altered allowing the print density to be controlled.
Epson AcuLaser CX-11N/AcuLaser CX-11NF Field Repair Guide 9/9/05 Step 4: Image Transfer During the image transfer stage, the image that is now visible on the OPC Drum is transferred to the media. As the media moves through the paper path, it makes contact with the OPC Drum. The media is charged with a positive charge causing the toner to be attracted to the media.
Epson AcuLaser CX-11N/AcuLaser CX-11NF Field Repair Guide 9/9/05 Step 6: Fusing Figure 7: The toner image is permanently bonded to the media by the heat roller and fuser belt. With the toner now resting on the media, the printer moves the paper through the paper path to the Fuser where heat heat is applied to permanently bond the toner into the media. As the media passes into the Fuser assembly, the Heat Roller and the Fuser Belt are used to bond the toner image into the media.
Epson AcuLaser CX-11N/AcuLaser CX-11NF Field Repair Guide 9/9/05 Step 7: Cleaning The final step in the laser printer image formation process is the cleaning stage. During the cleaning stage, any lingering toner residue that was left on the OPC Drum needs to be cleaned off before the next image can be created. Since this toner cannot be reused, a Cleaning Blade is used to remove the residue from the OPC Drum and deposit it into the Waste Toner Box.
Epson AcuLaser CX-11N/AcuLaser CX-11NF Field Repair Guide 9/9/05 Color Laser Printer Image Formation The color laser printer image formation follows very similar processes to that of monochrome laser printers. With the color laser printer however, there are a few differences; • 3 color Toner Cartridges are used along with black for CMYK printing • Each color of the image is transferred to the OPC Drum in a separate operation.
Epson AcuLaser CX-11N/AcuLaser CX-11NF Field Repair Guide 9/9/05 Each color of the image is transferred from the OPC Drum to the Transfer Belt until all color images are formed. The colors are transferred from darkest color to lightest color (Black first, Magenta second, Cyan third, and Yellow last). Each one of these transfers are called the “Primary Transfer.” Then the “Secondary Transfer” stage occurs - the transfer of the image to the media.
