Envelope Lever
Envelope levers are provided on the right and left side of the fusing unit. When the lever is pulled down,
the fusing pressure decreases (approx. 55% of the usual), and wrinkles on the envelope are controlled.
Since no sensor to detect the lever position is provided, make sure to pull up the lever after printing on
an envelope.
At the time of shipment, the lever is lowered (Envelope mode) to prevent deformation of the pressure
roller. When not using the machine for a long time, leave the lever down.
