The unit requires it's own drivers from Lexmark, Microsoft's won't work. Machine doesn't feed faxes properly, resulting in a CLR DOCUMENT JAM error every time, only clearable by unplugging the machine, but it will occur any time you use the scanning element - basically, if you want to scan, copy, or fax - you're [messed up]. As a printer, it's majorly slow, and the quality is very bad. Would rate it a 0 if it was allowed.
