Determining Fan Functionality on a Lexmark CS310, CS410, CS510, CX310, CX410, and CX510


This article will discuss the proper functionality of the printer's main fan.

Proper Fan Operation

The printer's fan has to run at various times to cool down the machine, and in a hot environment it will have to run more often than otherwise. It is NORMAL for the fan to run:

  • Briefly during startup.
  • At all times during printing. Revolutions per minute (RPM) will vary based on the print job's length.
  • The exact time the fan will continue to run after the printer finishes a print job varies as this will depend on the environment and the length of recent print jobs. The fan will run until the printer reaches a safe internal temperature.

Abnormal Fan Operation

It is NOT NORMAL for the fan to run:

  • When the printer is in sleep mode (screen off, sleep button lit).
  • When the printer is in idle mode (printer in "Ready" state), unless the printer is in a very warm environment.
  • When the printer is in an error state (i.e., paper jam). The printer should act the same as it does in idle mode.



If the printer's fan is running too often, please update to the latest firmware.
