another name for drum roller for printer
The drum unit transfers the toner to the paper. The laser printer puts the toner on the roller called The photosensitive drum inside the drum unit, and then prints letters and images by fixing toner to the paper by heat and pressure. To keep good print quality, the Brother machine detects the quality deterioration of the drum unit automatically. In the early laser printers, the on/off status of the laser could be changed 300 times per inch, and the drum rotated 1/300 of an inch with each horizontal sweep of the laser, resulting in a 300 dots per inch (dpi) maximum resolution. Today’s laser printers can achieve 600 dpi or even 1200 dpi. Step 4: Paper feed. The drum of a laser printer is responsible for transferring the toner and image or text to the paper. It has several different names, and you might hear it referred to as the image drum, imaging unit, drum unit or photoreceptor drum. For a drum to transfer the text and toner to the page, it first receives a positive charge from the corona wire. Fusers dont last long typically 100,000 to 200,000 pages is all there good for most printer. manufacturers will say they last longer and all printers are rated differently concerning fuser life expectancy. but by running envelopes and heavy paper stock through the printer you will cause your printers.

Color LaserJets are a bit trickier to troubleshoot in regards to light print than black and white printers. The transfer process involves four toners instead of one. Most color LaserJets have a transfer belt (ITB) and some designs separate the photosensitive drum from the toner cartridges. 3. Fuser. The fuser is the part of the printer that bonds toner to the paper through heat and pressure. Fusers DO NOT have a built in supply of toner, they only bond toner that is already on the paper. Therefore fusers can not cause light print, unless the toner is sticking to the fuser’s upper roller.
