Epson STYLUS PHOTO 2000P Instruction Manual page 24

Note:
The folding quality and thickness of envelopes varies widely. If the
total thickness of the stack of envelopes exceeds 10 mm, press each
envelope in the stack flat before loading.
❏ Set the adjust lever to the "+" position. To do this, open the
printer cover and reposition the lever.
Note:
❏ Return the adjust lever to the "0" position, which is the normal
position, after you finish printing on envelopes. Leaving the
lever in the "+" position may cause gaps to appear in images
printed on other media.
❏ When the adjust lever is in the "+" position, make sure the High
Speed setting in the printer driver's Advanced dialog box is off.
To turn this option off, you may also need to change the Print
Quality setting.
❏ Load envelopes flap edge first with the flap side down, as
shown in the illustration.
❏ Do not use envelopes that are curled or folded. Make sure to
flatten the envelope flaps before loading. Also avoid using
envelopes that are too thin; they may curl during printing.
