BIOS Magazine posted a review on the Lexmark X9575 Professional All-in-One

Similar to the X4875 and other models in the Professional Series inkjet line, the biggest selling point of the X9575 is the new warranty program from Lexmark that includes next-business-day replacement for up to one year after purchase. Furthermore, both high-yield and standard-yield cartridges are available for this series, should you intend to do larger print runs. At the top of the new line is the X9575, which offers built-in automatic two-sided printing, colour print speeds of up to 5ppm (11ppm for black), a 48-bit flatbed colour scanner, and pigmented inks that are highlighter, water and smudge.
