The envelope lever (Pressure release lever) [A] is also used by the operator to adjust the size of the gap between the pressure roller and hot roller. A larger gap is needed for envelopes, which are thicker than paper.

The fusing pressure release sensor [B] detects whether the envelope lever [C] is set to the envelope position. A warning will be shown on the LCD if the envelope lever is set when normal paper is being fed, and vice versa.

  • Lower the lever [2] to increase the size of the gap between the hot roller and pressure roller. This prevents jams and wrinkling when printing on envelopes.
  • Raise the lever [1] to reduce the gap for all other print jobs. Normally this lever should be up.

  • Both envelope levers should be set to the same position at the same time, Otherwise a warning will be shown on the LCD to prevent paper jams.
