Page 181: Theory Of Operation
Theory of operation Print engine theory Electrophotographic Process (EP Process) The method that all laser and LED printers use to print is called the electrophotographic process. These machines use differences in charge to manipulate and move toner from the toner cartridge to the printed page. Even though the basic EP process is the same for every laser and LED printer, the specifics for each printer are different.
Page 182: Step 1: Charge
Step 1: Charge During the charge step, voltage is sent from the high-voltage power supply to the charge roller (A) beside each of the four photoconductors. The charge roller is part of the photoconductor unit. The charge roller (A) puts a uniform negative charge over the entire surface of the photoconductor to prepare it for the laser beam.
Page 183: Step 2: Expose
Step 2: Expose During the expose step, the laser fires a focused beam of light at the surface of each photoconductor (B) and writes an invisible image called a latent image or electrostatic image for each color. The laser beam actually discharges the surface only where the beam hits the photoconductor. This creates a difference in charge potential between the exposed area and the rest of the photoconductor surface.
Page 184: Step 3: Develop
Step 3: Develop Once the laser exposes the photoconductor, the high-voltage power supply sends charge to the developer roll (C). For each color, the toner cartridge engages the photoconductor so it is in contact with the surface. Because of the charge difference between the toner on the developer roller and the electrostatic image created by the laser, the toner will attract to the photoconductor only where the laser exposed the surface.
Page 185: Step 4A: First Transfer
Step 4a: First transfer When the latent images are developed on each Photoconductor, the high-voltage power supply sends voltage to the 1st Transfer Rollers inside the ITU (D). The charge difference between the developed toner image on the Photoconductor surface and the 1st Transfer Roller causes the images to transfer to the surface of the ITU belt for each color.
Page 186: Step 4B: Second Transfer
Step 4b: Second transfer Once the four planes of color are transferred to the transfer belt from the photoconductors, the image is carried towards the transfer roll (E). This transfer roll is also part of the ITU. Based on the speed of the transfer belt, the proper time to send the signal to pick the media from an input source is determined.
Page 187: Step 5: Fuse
Step 5: Fuse Once the image has been fully transferred to the media, the transfer roll helps move the paper into the fuser area. The fuser (F) applies heat and pressure to the page to melt the tiny toner particles and bond them permanently to the media.
Page 188: Step 6: Clean/Erase
Step 6: Clean/Erase There are two main cleaning processes that take place during the EP Process. One process cleans the transfer belt, and the other cleans the photoconductors. Transfer Unit Clean Once the toner image on the transfer belt has been transferred to the page, the transfer belt rotates around and is cleaned by the cleaning blade (G).
Page 189 Photoconductor Clean/Erase After each plane of color has been transferred to the transfer belt from the photoconductors, a cleaning blade (H) scrapes the remaining toner from the surface of each photoconductor. This is the clean/erase process. Now the photoconductor surface is prepared to begin the EP cycle once again. This cleaning/erasing cycle happens after each plane of color is transferred to the transfer belt.
Page 190: Paper Path, Transport Components
Paper path, transport components In order for an image to be printed, the media has to be moved from an input source (such as a tray) into the printer and eventually exit into an output source. The most important component in this process is this media itself. Old, damaged, or out-of-specification media can and will cause feed and transport problems.
Page 191: Transport Components
Transport components In summary, the media is fed from the tray into the printer by a feed roll and carried to the transfer roll (ITU). The pick rollers time the media to enter the EP process at just the right moment. The pick rollers push the media to the ITU where the image is transferred to the page.
Page 192 When the trailing edge of the media clears the fuser, the fuser engine rotates forward to prepare the fuser for the page travelling through the duplexer. As the media reaches the gate aligner, a sensor (S1) is triggered indicating the presence of the leading edge. When the S1 sensor is triggered, the paper continues to the S2 sensor.
Page 193: Scanner Theory
Scanner theory Duplex ADF The following illustration shows the paperpath, rollers and sensors used in the MF923 duplex ADF. The MF923 duplex ADF enables the user to create duplex scans automatically, eliminating the need to stop the scanning process to flip the media being duplicated over. The ADF uses a step motor, and a series of sensors to determine the media’s position in the paper path during the scan process.
Page 194 with the ADF scan sensor ensure that the media is travelling at the correct speed through the scan area. The speed the document travels through the ADF scan area is dependent on the image DPI specified by the user. 7. After a predetermined number of counts, the media reaches the scan area and the image acquisition process is initiated.
Page 195: Color Theory
Color theory What is RGB color? Red, green, and blue light can be added together in various amounts to produce a large range of colors observed in nature. For example, red and green can be combined to create yellow. Televisions and computer monitors create colors in this manner.
Page 196: My Color Transparencies Seem Dark When They Are Projected. Is There Anything I Can Do To Improve The Color
My color transparencies seem dark when they are projected. Is there anything I can do to improve the color? This problem most commonly occurs when projecting transparencies with reflective overhead projectors. To obtain the highest projected color quality, transmissive overhead projectors are recommended. If a reflective projector must be used, then adjusting the Toner Darkness setting to 1, 2, or 3 will lighten the transparency.
