Lexmark has implemented features in the X73xde Series MFPs that allow our customers to easily select various
operating modes in order to reach their sustainability goals related to environmental and noise pollution. These
new features are Eco Mode and Quiet Mode.
Eco Mode optimizes printer settings to minimize the environmental impact while Quiet Mode significantly

The parameters that are changed are returned to their factory default state. This mode will
support performance claims for the product.
MFP will be configured to run in a reduced noise mode. Primarily, the user is trading
performance for quieter operation. The following parameters are affected:
• Process speed is reduced
• Key press sounds and alarms, for example, are disabled or minimized
• Engine motors are not ramped up prior to the job being ready to actually print
• Fans run in reduced speed or are turned off
