Samsung SCX-4521FG Envelopes with Double Side Seams, Envelopes with Adhesive Strips or Flaps

Envelopes with Double Side Seams

Double side-seams construction has vertical seams at both ends of the envelope rather than diagonal seams. This style may be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as illustrated below.

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 machine. The extra flaps and strips might cause wrinkling, creasing or even jams and may even damage the fuser.

Envelope Margins

The following gives typical address margins for a commercial #10 or DL envelope.

Type of Address	Minimum	Maximum
Return address	0.6 in. (15 mm)	2 in. (51 mm)
Delivery address	2 in. (51 mm)	3.5 in. (90 mm)

NOTES:

•For the best print quality, position margins no closer than 0.6 in. (15 mm) from the edges of the envelope.

•Avoid printing over the area where the envelope’s seams meet.

Envelope Storage

Proper storage of envelopes helps contribute to print quality. Envelopes should be stored flat. If air is trapped in an envelope, creating an air bubble, then the envelope may wrinkle during printing.

Labels

CAUTIONS:

•To avoid damaging the machine, use only labels recommended for laser printers.

•To prevent serious jams, always load one sheet of paper at a time to print labels.

•Never print on the same sheet of labels more than once and never print on a partial sheet of labels.

When selecting labels, consider the quality of each component:

•Adhesives: The adhesive material should be stable at 180°C (356°F), the machine’s fusing temperature.

•Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets with spaces between the labels, causing serious jams.

•Curl: Prior to printing, labels must lie flat with no more than 5 in. (13 mm) of curl in any direction.

•Condition: Do not use labels with wrinkles, bubbles or other indications of separation.

Transparencies

Transparencies used in the machine must be able to withstand 180°C (356°F), the machine’s fusing temperature.

CAUTION: To avoid damaging the machine, use only transparencies recommended for use in laser printers.
