Envelope
Print on the front (address) side only. Some parts of the envelope consist of three layers of paper—the
front, back, and flap. Anything printed in these layered regions may be lost or faded.
You can print continuously with envelope. However, this could affect the media feed, depending on
the media quality and printing environment. If problems occur, stop the continuous printing and
print one sheet at a time.
