  OVER 100
IN STOCK NOW

Price:  $28.89
Product Description
Brother MFC-8640 All In One Machine Drum - 20000Pages

This Drum is good for printing 20000 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.

How to Install a Drum Unit in the Brother MFC-8640 Multifunction Center
In the initial step of the replacement procedure, you must open the front cover of the laser printer, and then take the drum unit and toner cartridge assembly out of the print compartment. Next, you must remove the toner cartridge from the exhausted drum unit by pulling it towards you while holding the release lever on the right down, and then unpack the replacement component. After that, you must insert the toner cartridge into the new drum unit until it locks into place, and then install the assembly into the Brother MFC-8640 Multifunction Center. Now, you must press the [Clear/Back] button, and then press [1]. Finally, you must close the front cover of the multifunction center.

Brother MFC-8640 Review


Overview:

The Brother MFC-8640D was a variation on the brand’s popular line of print, copy, scan, and fax ready all in one units. The device was also available in a base model and a network ready model, adding a level of versatility and selection unseen in other brands’ models. Unfortunately, the device’s dated hardware leaves it stranded firmly in the obsolete category.


Pros:

The most notable feature of the Brother MFC-8640 is its duplexing capabilities. With the addition of automatic two sided printing, copying, and fax receiving, the unit hangs on to relevance a little longer due to the uniqueness of this hardware feature. With duplex printing, paper usage can be cut down by as much as fifty percent, and two sided pamphlets and manuscripts will have an additional feel of professionalism.

The Brother MFC-8640 is also a fairly sturdy piece of hardware, boasting a strong 20,000 page per month maximum duty cycle, along with a one year factory warranty. It’s mushroom shaped flatbed design is made to fit a full legal sized document glass that can scan and copy three dimensional objects as well as individual sheets of paper. The unit’s built in automatic document feeder is another convenient way to scan input material when dealing with multiple sheets at once.

Interestingly enough, the Brother MFC-8640 excels as a fax machine. With a huge range of comprehensive fax functions and a collection of one touch dial buttons, the unit is absolutely top of the line in this category. A built in fax page memory of 400 sheets (expandable up to 480 sheets) is the perfect failsafe feature for protecting incoming fax data that cannot be printed immediately due to paper outages or an occupied printer.

The device comes equipped with room for up to 240 auto dial locations and a broadcasting function for up to 290 locations. Possibly the most outstanding fax specification that the Brother MFC-8640 boasts is its speed. With a built in Super G3 fax modem, the device is fully capable of transmitting faxes at 2 seconds per page.


Cons:

With a print speed topping out at just about 20 pages per minute in black and white, the Brother MFC-8640 falls noticeably behind its more current competitors in the area of raw speed. Its copy and scan speeds match the device’s 21 page per minute rate of print, while other notable areas, such as built in memory, also leave much to be desired.

The Brother MFC-8640’s 16 MBs of on board RAM is not enough to prevent significant slowdown when dealing with large, complex print projects. Like many Brother electronics, this unit’s memory is expandable, but with the high cost of additional RAM, buyers would be wiser to invest their money in a newer unit.
