This is the ultimate monochrome laser killer. It delivers 100 ppm performance with inkjet running costs, reliability, and sustainability – no heat, no drum replacements, no fuser failures, and power consumption as low as 320 W at full speed. First page out in ~4.9 seconds, virtually silent operation, and service intervals measured in years. For any organization currently running multiple 75–120 ppm monochrome lasers (or paying huge electricity/toner bills), the WF-M21000 consolidates everything onto one greener, quieter, lower-cost machine without sacrificing speed or quality.
