A:AnswerYou don't need the CD. I followed the directions and downloaded software online. You can set it up this way. I definitely recommend you follow step by step directions. Once you download the software, you can do a number of things including maintenance... The Brother software showed up on my desktop.
A:AnswerNot sure if this will help but did you go to the maintenance section of the downloaded Brother software on your computer? Without seeing the jam, I'm not sure if this helps.
A:AnswerMine have not had problems, but if it looses connection, turn it off and wait a few minutes and turn it back on. That should allow it to reconnect. I've done this with other printers that have had that problem.
A:Answerthe 2700 is grey and the 2740 is black. The 2740 does duplex color scanning while the 2700 only scans one side of the document. The 2740 is a tad heavier. They have same memory and same dimensions.
