This would be especially true when you have been handling the maintenance of your laser printers yourself. However, the difference between drum units vs. As such, in this blog article we will simplify the comparison by explaining the key differences between drum units and toners. Take a look at our experts' guide to understanding the differences. In short, the toner cartridge is a container that contains the toner powder, whereas the drum unit is an electrically charged cylinder that transfers the powder onto paper.
Without a drum unit, the toner powder is unable to be transferred onto a piece of paper, which is why both parts are essential components for producing a print. While both the toner cartridge and drum units are essential for printing onto a piece of paper, although you may not have physically come into contact with the drum unit. Under the hood, the laser printer is a very complex machine with many internal components working in tandem to create that crisp printed image on your page.
With lasers, mirrors, photoconductor drums, rollers, and fusing units, all being essential to the printing process. These parts must be properly maintained and replaced as needed. While most of these parts are directly built into the machine, some of them, like the printer drum, can be removed. It may come as a surprise for some, but drum units need to be replaced every so often to keep up the quality of the printing. Drums are the shell that toner cartridges are placed in and allow for the toner to adhere to the paper.
Drum units are items that, alongside toner cartridges, need to be replaced after consumption. Many consumers have the "If it ain't broke, don't fix it" mentality. But the replacement of a drum unit is vital to laser printers' health. A degraded drum unit can cause streaks, smudges, and blank spots on your printed page even if you just inserted a new printer toner.
While a broken drum unit won't break your printer, it will just fail to stop printing at a certain point. Sadly, there are no special tips to get around this pesky occurrence, and it doesn't matter whether you're using a brand name cartridge or cheap printer ink replacement. Why do I need to replace the drum in my Brother printer? Below, you'll learn why replacing them is essential to the quality of your laser printer. It is important to remember that drum units need to be replaced every so often to maintain good print quality.
Just like their toner or ink cartridge counterpart, drum units have a shelf life as well that a consumer needs to be aware of. Smaller laser printers can have a drum no wider than a pencil. Regardless of size and color, the primary function of the drum unit is to attract the toner powder particles via electrostatic polarities and transfer the toner to the paper.
While the drum receives the electric charge and the image is drawn, the rest of the drum unit stays neutral. A drum uses an electrostatic charge to attract the toner powder particles which are put on a photosensitive roller inside the drum unit.
The electrostatic charge is then used to draw the image on the drum that is transferred onto the paper and printed on the page later in the process. In most laser printers, the drum and toner are housed in a single cartridge. However, in some machines the two units are separate. The advantage here is you can replace toner without having to replace a printer image unit, and vice versa.
You can replace toner cartridges three or four times before you need to replace an imaging unit or drum. Many models of Brother laser printers have separate Brother toner cartridges and printer drums.
The Brother printer drum comes in a separate cartridge that snaps together with the toner cartridge to form one unit. Brother printer drum units and Brother copier drums can be cleaned and replaced as needed. Brother laser printer drum life depends on how frequently you print. Other printer manufacturers that use a separate toner and drum configuration include Epson, Oki , and Panasonic.
HP laser printers usually have the HP imaging drum built into the HP toner cartridge so when you replace one, you automatically replace the other.
Replace the drum unit when you get white lines on your pages. The answer depends on how often you print. In general, a printer drum lasts about three or four times longer than your toner cartridges.
Which is better: separate toner and drum cartridges or all-in-one cartridges? So, why the inconsistency? It is all contingent on the design of your printer. A drum unit can be incorporated with the toner cartridge or sold separately as a single unit, depending on the consumable requirements of your printer. Laser printers and their consumables vary across printer models.
Some printers only need you to replace the toner cartridge, and others require that you regularly replace both the toner cartridge and the drum unit. Most printers use toner cartridges with the drum unit built into the cartridge. If you own an HP laser printer , for example, the drum unit is likely incorporated into the toner.
Therefore, there is no need to replace the drum separately. Every time you buy a new toner for that HP printer, you are replacing the drum. Some printers, like most Brother laser printer models, use a separate toner and drum unit.
In this case, the drum unit is not built into the toner, and therefore, must be replaced.
