Push to release the latches of the corona wire cover (1), and then open the cover. NOTE: We recommend you place the toner cartridge(s) on a clean, flat surface with a piece of paper underneath it in case you accidentally spill or scatter toner.Ĥ.

NOTE: If you cannot pull the drum unit out, make sure that the front cover is fully open.ģ. Press down on the front cover release button and open the front cover by pulling it towards you.Ģ. To clean the corona wire, follow the steps below:ġ. View All Brother Care Program Eligible Products.View All Refurbished - Sewing & Crafting.View All Refurbished - Fax Machines & Scanners.And if the cleaning process is unsuccessful, consider replacing the drum or the corona wire altogether. Make sure you are gentle, as the corona wires are quite sensitive. Please check your manuals to identify which method of cleaning is appropriate for your machine. Use Q-tip and alcohol to gently clean the wire.Reinsert the cleaning tool and the wire.Insert the tool into the underside of the corona housing.Remove the provided cleaning tool that is inside the printer, right below where the corona wire sits.To remove the corona wire, pinch the handle of it and pull.When complete, match the arrow on the tab and the arrow on the cassette before reinserting.Locate the blue tab on the assembly and gently slide it from left to right repeatedly.If the corona wire is not cleaned, the quality of the prints will begin diminishing and faded coloring or streaks may appear on the printed page. They should be cleaned every time cartridges are replaced. The corona wire then gives an even stronger negative charge to the paper so it can pull the toner from the imaging drum.Ĭorona wires take a beating and collect a lot of dirt and excess toner. This negative charge attracts the positively-charged toner. The corona wire receives a blast of high voltage, which it then transfers to the written image on the drum in the form of static electricity. When data is transferred, the laser writes the image onto the drum. The imaging drums sits in the middle of the machine, flanked by rollers, corona wires, a fuser and a toner cartridge, unless it is a Brother unit, then the Brother toner cartridge is within the drum assembly. These make it challenging to generalize cleaning techniques and give "how-to" instructions.Īs you may assume from the terminology, laser printers are known as such because the images and text that is to be printed is written with lasers. Though laser printers generally have the same components, the interior functionality and design have small differences that are unique to each manufacturer. However, this wire is one of the single most important parts of any laser printer, and it doesn't require a lime. This may even be the first time you have ever heard the word "corona" outside of a cold one on a hot day. Let's start with the obvious- what is a corona wire?Ĭhances are if you are not a printer technician, you have no idea what the answer is.
