The model itself
Of the speeds in Lexmark's MX91x series, the MX910de (first released in 2014) is the one that does 45 pages a minute. Lexmark made one sister model, the MX912dxe, at 65 pages a minute. From the maker's own figures, it reads both sides of a double sided original in one pass, at as many as 80 images a minute, has room for 1,150 sheets (or 6,650 with extra paper options) and copes with card stock to 256 gsm.
