Problem Cause Solution
When printing to envelopes,
the envelopes may be fed in
together, or the envelopes
may not be fed.
The envelopes are curled. Make sure you fully flatten curled
envelopes before you load them. Do
not stack envelopes over the specified
limit for the paper tray.
If misfeeds still occur after the
envelopes have been flattened, load
envelopes on the tray one at a time
and print them individually.
For details about how to load
envelopes, see page 205 "Envelopes".
