Labels are paper with pressure-sensitive adhesive. Acceptable sizes are
Letter and A4.
Note the following conditions when choosing a label sheet:
❏ The label print face (top, or face sheet) must be made of ordinary,
matte-ﬁnish paper similar to copy paper.
❏ The paper backing must be able to withstand the heat generated by the
ﬁxing assembly (about 190˚ C or 374˚ F). The backing must not be
made of easily removable coated paper.
❏ Do not use labels with exposed adhesive, which may stick to the EP-
22 cartridge or the ﬁxing roller, causing the labels to peel off and
serious paper jams to occur.
Follow these guidelines when printing on envelopes:
❏ Envelopes must not have any fasteners, snaps, or windows, or be made
of artiﬁcial materials.
❏ Do not use envelopes that discolor or melt at about 190˚ C (374˚ F),
envelopes which might emit dangerous fumes when heated, or
envelopes that seal with pressure-sensitive adhesives.
❏ Do not use envelopes which are damaged, curled or wrinkled, or that
have an irregular shape.
❏ Do not use oversized envelopes, or envelopes with folds.
