Handholds Handholds Choosing the new location for your Lexmark C720 printer is vital to ensuring the printer provides you with the quality of service you expect. When selecting a place to set up your printer consider: · · The amount of space your printer and any options will require The type of environment necessary for optimum printer performance For more information on the amount of space your printer requires, environmental consideration, and instructions on setting up your printer, refer to the Setup Guide. 132 23 Theory of operation By understanding how the toner cartridges, photo developer cartridge, transfer drum, transfer roller, and fuser interact you can understand why problems occur and how to correct or prevent them. Output tray Photo developer cartridge Fuser Toner cartridges Transfer roller Laser emitter Transfer drum Paper trays Photo developer charger The green film inside the photo developer is a belt that makes a continuous loop as your printer operates. The photo developer charger (the thin wire on the bottom of the photo devleoper), places a uniform negative charge on the surface of the green film (photo developer media) as the media travels past the photo developer charger. As the media moves toward the toner cartridges it passes the laser emitter inside your printer. The information you send to your printer is changed into a laser-emitted signal. This signal is projected onto the photo developer media and discharges portions of the media. The discharged areas on the photo developer media pull negatively charged toner particles from the toner cartridges into the discharged areas on the photo developer media. As the photo developer media rotates, it meets the transfer drum. The transfer drum has a uniform neutral charge on it. When the transfer drum and photo developer meet, the image on the photo developer media moves from the media onto the transfer drum. As the transfer drum rotates toward the rear of the printer, the paper is pulled from the paper tray and travels up the paper path to meet your image. The paper or other media (such as transparencies or envelopes), arrives at the transfer roller and transfer drum just prior to your image. 133 The transfer roller is located on the inside of the rear door of the printer. It has a strong uniform positive charge on the roller. The positive charge on the transfer roller goes through the paper to the transfer drum.
