Product Description

Brother MFC-9840CDW Drum Unit - 17,000 Pages


This Drum is good for printing 17000 pages, on average. Average page coverage is 5% of toner per page (compared to white space on the paper), which is the standard Brother specification for this drum, and a standard measuring term for the consumer printing industry.


This product comes with a 6 month Warranty against any defects (including free replacement). We stand behind our products 100%, as these are not manufactured by Brother.

What's the difference between a drum and a toner cartridge? A toner cartridge is just that: a cartridge that contains toner. The drum does all the work.


Product Manuals
How to Install a Drum Unit in the Brother MFC-9840CDW Multifunction Printer
You must start the drum unit replacement procedure by turning off the power switch of your Brother MFC-9840CDW Multifunction Printer, and then open the front cover by pushing down its lock release button. After that, you must grab the green handle of the exhausted drum unit and pull upwards, and then pull the exhausted drum unit towards you until it stops. Now, you must unlock the exhausted drum unit by releasing the gray lock lever on the left side of the printer, and then take the exhausted drum unit out of the printer. Please note that you must avoid touching the components surrounding the installed drum unit, the photoconductive drums of the new drum unit, and the contact areas of the toner cartridges. In the next step of the replacement procedure, you must detach all toner cartridges from the exhausted drum unit by grabbing each cartridge's handle and pulling upwards. Once all toner cartridges are detached, you must take the new drum unit out of the transport packaging, and then remove its protective plastic cover. Then, you must insert all of the previously removed toner cartridges into the new drum unit by following this order (front side of the new drum unit-rear side): Black (K), Yellow (Y), Magenta (M), and Cyan (C). After that, you must make sure that the toner cartridges' handles are folded down and that the gray lock release lever is still in ''upper''/''unlocked'' position, and then insert the drum unit into the printer slot until it stops. Now, you must push the gray lock release lever down, and then slide the new drum unit into the slot until it stops. Finally, you must gently push the new drum unit down to lock it into the slot, and then reset the drum counter by executing the procedure included below.

Reset The Drum Unit Counter

Close the front cover and turn on the printer.
Navigate to the [84. Reset Menu] by pressing [Menu] – [8] – [4].
Use [^] or [v] to choose [DRUM].
Press [OK], and then press [1].
Finalize the drum counter reset procedure by pressing the [Stop/Exit] button.
When do I Replace a Drum Unit in the Brother MFC-9840CDW Multifunction Printer?
The drum unit installed in your Brother MFC-9840CDW Multifunction Printer must be replaced after a certain number of prints/copies, because it is a consumable printer component which has a limited printing resource. Therefore, the installed drum unit is constantly monitored by a precise built-in system, and once a drum unit status abnormality occurs, you will see the following warning message ''Change Parts DRUM'' appearing on the control LCD of your printer. You should install a new drum unit soon after the initial appearance of the above warning, in order to be avoided a variety of print quality issues caused by an exhausted drum unit. You could easily replace the drum unit in your MFC-9840CDW by executing the replacement procedure included below.

Brother MFC-9840CDW Review


Overview:

There are many powerful printers out there, but not many come as powerful as this. The Brother MFC-9840CDW can do all of the basics that you would expect such as printing, copying, scanning and faxing, but also has some amazing features that make it a stand out from the rest. It features high quality printing in color, as well as duplex printing and wireless networking. This makes it a very powerful machine. Read below to find out more what this can offer.


Pros:

There are too many good features on this machine to say that one is the main function. It features color printing, which is not always possible on a lot of office machines, especially in this price range. Don’t be mistaken though; even in color it can reach high speeds and high quality. It is possible to print out at 20 pages per minute in black and white and in color. It even has very good quality, and can print out at a resolution of u to 2400 by 600 dpi. This is a very good quality, and will give your images a very professional look.

Duplex printing is another main feature this machine can offer. This is basically a function that allows you to print on both sides of the paper automatically, without the need to manually do it yourself. This will save you time as you don’t need to open up the paper tray and turn document around yourself. It will also save the business money as you are saving on paper. Overall this is a very convenient feature that will make working easier and faster.

Another one of the machines main features is the wireless networking abilities. This allows you to connect to the machine through a network, and using no wires. Having a network is something that every office, no matter how big or small will have. If more than one computer needs to connect to the MFC-9840CDW then this is definitely the way forward. It means that you can access some of its features such as printing, scanning and faxing directly from your computer.

The copying function on this machine is also quite good. It isn’t as fast as printing though, and only reaches up to 16 pages per minute when copying in color and black and white. You even have a duplex copying option that will automatically turn the document around for you. There is a reduction/enlargement feature with the copier that can perform at a ratio of between 25% and 400%.

The scanning feature can reach a resolution of 19,200 dpi when scanned at enhanced mode, and 1200 by 2400 dpi when scanned at optical resolution. Its scan to feature allows you to transfer scanned images directly to your computer over the wireless network for easy access and editing.


Cons:

With every machine there is going to be a few small disadvantages. In this case, it is the print and copy speed. Although this machine can achieve almost everything else, it prints at 20 pages per minute and scans at 16 pages per minute. This is too slow if you are working in a medium to large office space. It should only be used in a home office or between a small workgroup.

The ability of color may be a very useful feature to some, but running costs can be dramatically increased. It is important to only use the color when you generally need it and not just because it is there. Color cartridges can cost a lot of money to refill, and won't last as long as black and white. Also documents might get accidently printed out in color when they were meant to be in black and white. This is a very common mistake and could easily be made by a novice user.


In all, this machine is fantastic. For the every day user, it is what you expect from a machine of this price. It has the standard features you would expect on every all in one machine, plus the added ability of duplex printing, printing in color and wireless connectivity.
