The Bubbling of this roller then leads to the embossing as seen in the left print. You will notice the rubber under the black microsleeve on the roller has lifted off and bubbled. The Toner powder used in these compatible cartridges is not the same compound and when it melts in the fuser by the roller it bonds like glue to the roller, because the lift off angle is greater than previous models these two combined factors eventually pulls the rubber off the roller. There are reasons why the Genuine Toner costs $138.00 and these online sellers are only $18.00 and it comes down to the powder. The bubbling/lift off problem is sped up and often begins through the use of certain so called 'Compatible Toners' sold by a handful of popular Online dirt cheap cartridge selling companies. Unlike its predecessor the MFC9140cdn has a fuser roller that is half its size of the MFC9120cn this has increased the paper lift off/separation angle as a result. In this series of Brothers, they have reduced the size of their upper fuser roller and thereby reduced the amount of aluminium and rubber used to produce the roller. This Low price and ability to accept aftermarket toners Though has proven to be its Achilles heel.

These machines have proven to be very popular due to their high number of features including network connectivity (wired and wireless) ability to easily work with aftermarket and refilled toners and its comparatively low Purchase price. The BROTHER MFC9330CDW/MFC9140CDN/MFC9340CDW/H元140 Series Colour laser printer/MFC has been sold by the truckload in the past 1-2 years since its release.
