Nowadays, laser printers have become the mandatory office accessory in most of the home and offices for producing superior quality printouts at faster speeds. Probably, you can easily find one in almost everywhere including schools, colleges, offices, and large organizations. Moreover, the significant innovations in laser printing technology such as color printing has made the laser printers a much demanded need for even the children and professionals to get the hard copy of their projects. But, did you ever try to find out the science behind the colored printing? Or what makes color printing possible? Well, the key component of getting high quality and clear colored printouts is the drum unit in a printer. Despite its importance in print mechanism, very few people have a clear idea about its role in the printing process.
What is a Drum Unit?
The printer drum unit is an important printing component which is responsible for producing quality-based images during the printing process. A drum unit attracts the toner particles through electrostatic polarities to create clear texts and images. Most of the printers that are available in the market these days comprise toner cartridges with in-built drum units. This is probably the reasons why most of the printers these days have better printing speed. However, the combination cartridges are not economical in the long run. In most of the cases, it has been found that the drum unit still remains in a good running condition even when the toner cartridge runs out.
How does the Drum Unit Work?
The laser printer drum unit serves as a photoconductive unit which is specifically designed to transfer and create digital images right into the surface of the drum. During the printing process, the documents which need to be printed is transformed into a raster image by the computer and then sent to the printer. The tiny laser beams from the printer laser scanning unit draw patterns on the surface of the drum unit to create images and texts. The surface of the drum unit is positively charged and the images and texts produced by the laser scanning unit is negatively charged. When the drum rotates, it attracts the negatively charged toner particles and the excess toner is wiped away by the cleaning blade to produce clean and quality printouts. Toner that remain on the surface of the drum unit then gets transferred to the paper. Once done, the paper then transferred to the fuser roller for the final bonding before it comes out over the paper tray.
Is it Possible that Laser Printer Work Without Drum Unit?
The simple answer is no. Laser printer depends on the drum unit for creating quality images and texts onto the paper. Without a drum unit, the printer is unable to produce any printout. It is what that makes printing possible.
Does Drum Unit Require Replacement?
Drum unit, as like other printer parts, requires replacement to maintain the efficiency and performance of the printer. The laser printer will produce poor quality prints even when you replace the old toner cartridge with a new one when a defective drum unit is being used for printing work. Replacing the drum unit with a new one will not only improve the printing quality but also adds operational life to your printer.
Hope, you have now a good understanding of the role of the drum unit in the printing process. As it plays a critical role in producing quality printouts, it is imperative to use the best quality drum unit like brother drum to improve the performance, efficiency, and life of the printer.
