● Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 in) of curl in any direction. ● Condition: Do not use labels with wrinkles, bubbles, or other indications of separation. Never use a sheet of labels that has already been run through the printer. Envelopes Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends on the quality of the envelopes. When selecting envelopes, consider the following factors: ● Weight: The weight of the envelope paper should not exceed 105 g/m2 (28 lb), or jamming might result. ● Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 in) curl and should not contain air. Envelopes that trap air may cause problems. ● Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise damaged. ● Sizes: From 90 x 160 mm (3.5 x 6.3 in) to 178 x 254 mm (7 x 10 in). Store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope might wrinkle during printing. Envelopes with double-side seams An envelope with double-side-seam construction (vertical seams at both ends of the envelope rather than diagonal seams) is more likely to wrinkle. Make sure the seam extends all the way to the corner of the envelope as shown in top figure of the following illustration: Should print well. May jam or wrinkle. Envelopes with adhesive strips or flaps Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives compatible with the heat and pressure in the printer: 200°C (392° F). The extra flaps and strips might cause wrinkling, creasing, or jams. Card stock and heavy media For optimum performance, do not use paper heavier than 157 g/m 2 (42-lb). Paper that is too heavy might cause misfeeds, stacking problems, paper jams, poor toner fusing, poor print quality, or excessive mechanical wear. 20 Chapter 2 Installation and Operation ENWW

Curl:
Prior to printing, labels must lie flat with no more than 13 mm (0.5 in) of curl in any
direction.
Condition:
Do not use labels with wrinkles, bubbles, or other indications of separation.
Never use a sheet of labels that has already been run through the printer.
Envelopes
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers, but also within a box from the same manufacturer. Successful printing on
envelopes depends on the quality of the envelopes. When selecting envelopes, consider the
following factors:
Weight:
The weight of the envelope paper should not exceed 105 g/m
2
(28 lb), or
jamming might result.
Construction:
Prior to printing, envelopes should lie flat with less than 6 mm (0.25 in)
curl and should not contain air. Envelopes that trap air may cause problems.
Condition:
Make sure that the envelopes are not wrinkled, nicked, or otherwise
damaged.
Sizes:
From 90 x 160 mm (3.5 x 6.3 in) to 178 x 254 mm (7 x 10 in).
Store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope
might wrinkle during printing.
Envelopes with double-side seams
An envelope with double-side-seam construction (vertical seams at both ends of the
envelope rather than diagonal seams) is more likely to wrinkle. Make sure the seam extends
all the way to the corner of the envelope as shown in top figure of the following illustration:
Should print well.
May jam or wrinkle.
Envelopes with adhesive strips or flaps
Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal
must use adhesives compatible with the heat and pressure in the printer: 200°C
(392° F).
The extra flaps and strips might cause wrinkling, creasing, or jams.
Card stock and heavy media
For optimum performance, do not use paper heavier than 157 g/m
2
(42-lb). Paper that is too
heavy might cause misfeeds, stacking problems, paper jams, poor toner fusing, poor print
quality, or excessive mechanical wear.
