10 Paper Handling Chapter 2
❏ Do not use labels with exposed adhesive, which may stick to the EP-
25 cartridge or the fixing roller, causing the labels to peel off and
serious paper jams to occur.
Envelopes
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.
❏ Poorly manufactured envelopes are not recommended.
