The new Lexmark mono, color, and MFP laser printers possess a new feature called, "Hibernation". Current printers having this feature are the Lexmark C792, X792, C925, and X925.(
Future products will also have it). This document outlines the difference between Power Saver (Sleep) versus Hibernation.

  • There is a product-specific default Sleep timeout.
  • Users can invoke Sleep by simply pressing the Sleep button.
  • Machine is completely available to the network, locally attach, and walk-up user.

Hibernate” mode is essentially OFF, plus the ability to turn off and on based on a schedule.

What’s the difference?

The Sleep and Hibernate optionshave different approaches toward power saving for Lexmark printers/MFP's. In some situations, Sleep is a better option; in other situations, Hibernation is.

Which should you use: Sleep or Hibernation?

Sleep is the most convenient. From Sleep,it takes only a few seconds for your printer/MFP to wake up. With Hibernate, you must to wait for it to start up again.
