Question about Office Equipment & Supplies
The top one of the array of lights is labelled drum - what is this? It flashes on for just a half second befoe the red alarm light shines by itself.
Brother laser printer HL-820
The drum is one of the most important major part of a laser printer. This part of the printer is so sensitive that fingerprints on it will ruin it and will cause poor print quality. If this is damaged then you will definitely need to have it replaced. This may cost a bit because it is a major component of a printer.
Laser printers works this way. A laser beam projects an image of the page to be printed onto an electrically charged rotating drum coated with selenium. Photoconductivity removes charge from the areas exposed to light. Dry ink (toner) particles are then electrostatically picked up by the drum's charged areas. The drum then prints the image onto paper by direct contact and heat, which fuses the ink to the paper.
