What Is the Difference Between a Drum Unit and a Toner Cartridge?

The process of replacing a toner cartridge is familiar to everybody who owns a laser printer. However, drum machines aren’t familiar to everyone. That said, let’s define them both first before we go any further.

What Is the Difference Between a Drum Unit and a Toner Cartridge

So What’s the Difference Between a Drum Unit and Toner Cartridge?

The toner cartridge is the container in which toner powder is stored. On the other hand, the drum unit is a cylinder charged with electricity that creates texts and images by fusing toner powder into paper.

Notably, both of these elements of the machine are required to create a print. Depending on your printer, you may be used to replacing your drum unit regularly, or you may have never had to do so. So, what’s the deal with the inconsistency? It’s all dependent on your printer’s design. This is because depending on your printer’s consumable needs, a drum unit might be included with the toner cartridge or offered separately as a single unit.

In addition, the consumables for laser printers differ depending on the model. For example, some printers simply require you to replace the toner cartridge. On the other hand, others require you to replace both the toner and the drum unit regularly. As such, always read through the user manual to know the products that suit your machine best.

HP Toners that Come With a Built-In Drum

If you have an HP laser printer, the drum unit is most likely built within the toner. As a result, the drum does not need to be replaced individually. This is because you’ll be replacing the drum every single time you purchase a new toner for your printer.

Toners and Drum Units That are Sold Separately.

In some cases, a separate toner and drum unit is used by some printers. This is the case for most printer types that are manufactured by Brother. Normally, the drum unit is not incorporated into the toner, which means that it must be replaced regularly. Remember, separate drum units survive far longer than toner cartridges and should be replaced after 3-4 toners have been used. Fortunately, when it’s time to replace the drum, your machine should notify you. However, whenever you start seeing black spots or lines on the page, it is time to replace the drum.


  1. Are toner and drum cartridges included with all new laser printers?

Yes, most laser printers come pre-installed with a starter toner cartridge. In addition, a drum is also installed where necessary.

  1. What is the point of having a drum?

The toner powder in the cartridge cannot be transmitted onto the page without a drum unit. To make a print, the two elements work together. Therefore, you can’t expect the printer to perform correctly if you don’t have both.

  1. Is it necessary for me to purchase a separate drum unit?

It is dependent on the laser printer’s brand. The drum unit is built within the toner cartridge in most HP laser printers. However, the drum units for Brother laser printers are sold separately, so you’ll need to replace them as you replace the toner cartridges. However, this should never worry you because you will have to use the machine for a long time before needing to replace the drum unit.

  1. Which printer type or brand is the best?

In terms of a “better” printer, there is no clear winner. Printers that employ toners with a built-in drum unit perform just as well as those that use a separate toner and drum. The only difference worth mentioning is the cost of consumables and how this affects their replenishment. For example, toners with an integrated drum are generally more expensive than toners that are purchased separately. That price rise makes sense because when you run out of toner, you’re essentially paying extra for new cartridges and drum units.

Justifying the Price Difference

Buying a new toner or drum combo every time ensures that your print quality remains consistent over the life of your printer. However, the premium cost adds up quickly, especially if the cartridges are above €100. On the other hand, a separate toner and drum unit have a somewhat different price breakdown. This is because separate toners are usually less expensive. After all, you just have to pay for the bottle that houses the toner powder. In addition, because the technology isn’t as complicated as that of a toner and drum combo cartridge, it’s less expensive to manufacture.

Regular Replacement of the Drum Unit

Keep in mind that the drum unit will need to be replaced at some point. As previously stated, a drum is normally replaced after 3-4 toners have been used. Drum units can cost as much as a hundred dollars or more, thus there will be an additional cost. In light of all these issues, customer preference determines which printer is better.

For instance, some customers choose to spend a little extra for the toner that includes a drum. That way, they don’t have to worry about print quality deteriorating over time or having to buy a separate consumable anytime their prints become splotchy. Others may prefer the instant cost savings of a separate toner cartridge and are willing to spend money on a new drum now and then.

Wind Up

Whichever printer type you choose, make sure to add in the cost of cartridges and drums. This is because it will help you to get a clear picture of long-term replacement expenses. However, if you are on a tight budget, always remember that compatible toner cartridges and drum units are a perfect choice. This is because they are a good way to save money on laser printers. For example, a compatible Brother DR-630 drum unit costs €26.00 against €85.99 for an original Brother DR-630, making the compatible choice 70% less expensive.

Hopefully, the information in this article helps you make a better purchase decision. Remember to seek expert opinion from reputable sellers if you have any queries concerning your toner or drum cartridge. Alternatively, use online reviews from previous customers before choosing a machine.
