Summary: I bought this printer 8 years ago when it first hit the market. I have NEVER had a single problem with it and it is still going strong. No jamming, no streaks, no weird errors. It prints clearly and is as reliable as the sun.
Summary: I got a 5240 as a giveaway from another resident in the apartment building with about 1200+ prints total on it according to the status sheet that printed out. I just plugged it in, connected it to my Mac laptop and I got asked if I wanted to download the driver. I clicked "yes" and away it went.
Summary: Like many others, I just cannot recommend this printer or any other Brother product. This is the second product from this manufacturer that I have owned. The first gave me multiple problems, even the second and third replacement units.
Summary: Like the other reviews you have, above, this line of printers wrinkles paper. The trouble shooting is of no help. Using the two-blue tabs at the back of the printer and flipping them can be of temporary assistance.
Summary: I have had this printer for 3 years in constant use for printing out .pdf files for research. I have had absolutely no major trouble. I inadvertently overloaded the paper feed and it jammed one time. Look for toner cartridges on line, Staples and Office Max too expensive.
Summary: Having owned an older version of this Brother laser printer for several years, we found ourselves with extra toner cartridges and a printer, though still working, that would only feed with its top-loading feeder and not the higher-capacity tray.
Summary: The printer is lacking network ports & other important features. Price looks great until you open the box & see everything it is missing. The company I ordered from has not called me back to exchange "Global Express' Does not have an operator or a live person you can talk too. Bad Deal!
