Laser Printer Naming Convention
Beginning in the fall of 2012, Lexmark changed the naming convention of its laser printers based on a 5-
digit identifier. The chart below outlines what each of these codes mean.
“M” for monochrome laser and “C” for color
“S” for single function and “X” for multifunction
Class: higher the number, greater level of performance and duty cycle
Gen: changes with each generation of product introduced in that class
Model: identifies the specific model within a class and generation
