An envelope is used.
Depending on the type of envelope, air trapped inside may be squeezed out
when the paper feed roller picks up the envelope and cause slippage leading to
a misfeed.
• Is the wide LCT fan disabled?
In [Advanced Settings] for the custom paper in use, set [01: Wide LCT Fan
Setting] to [Off].
• Have you flattened the envelope?
Flatten the envelope and all its edges to eliminate air before loading. If the
envelope is curled, decurl it before loading.
