If the delivered paper is curled, it cannot be stacked properly. In such a case, raise the paper stopper on the output tray and remove the paper frequently.

You can control the fuser temperature to prevent the paper from curling by User Tools.

Printer model: Menu > Maintenance > Quality Maintenance > Curl Prevention: Active (Default: Inactive)
MF model: User Tools > Machine Features > Maintenance > Curl Prevention: Active (Default: Inactive)

If set to [Active]:

  • The print speed drops (30ppm). Accordingly, the first print output time is delayed.
  • The fixing ability might worsen depending on the paper used.
  • If "Thick Paper 2" or heavier is selected, the print speed drops around 23ppm.
  • If "Thick Paper 1" or heavier is selected, idle rotation 10 seconds is added before printing.
