Dell 1130n Laser Mono Printer - Manual (Page 42)

Do not use damaged or poorly made envelopes.
Be sure the seam at both ends of the envelope extends all the way to the corner of the envelope.
1. Acceptable
2. Unacceptable
Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives
compatible with the machine’s fusing temperature about 170°C (338 °F) for 0.1 second. The extra flaps and
strips might cause wrinkling, creasing, or jams, and may even damage the fuser.
For the best print quality, position margins no closer than 15 mm from the edges of the envelope.
Avoid printing over the area where the envelope’s seams meet.
Transparency
To avoid damaging the machine, only use transparencies designed for use in laser printers.
Transparencies used in the machine must be able to withstand machine’s fusing temperature.
Place them on a flat surface after removing them from the machine.
Do not leave unused transparencies in the paper tray for long periods of time. Dust and dirt may accumulate on
them, resulting in spotty printing.
To avoid smudging caused by fingerprints, handle them carefully.
To avoid fading, do not expose printed transparencies to prolonged sunlight.
Ensure that transparencies are not wrinkled, curled, or have any torn edges.
Do not use transparencies that separates from the backing sheet.
To prevent transparencies from sticking to each other, do not let the printed sheets stack up as they are begin
printed out.
Labels
To avoid damaging the machine, use only labels designed for use in laser machines.
When selecting labels, consider the following factors:
Adhesives: The adhesive material should be stable at your machine’s fusing temperature about 170°C (338
°F).
Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets that have
spaces between the labels, causing serious jams.
Curl: Prior to printing, labels must lie flat with no more than 13 mm of curl in any direction.
Condition: Do not use labels with wrinkles, bubbles, or other indications of separation.
Make sure that there is no exposed adhesive material between labels. Exposed areas can cause labels to peel off
during printing, which can cause paper jams. Exposed adhesive can also cause damage to machine components.
Do not run a sheet of labels through the machine more than once. The adhesive backing is designed for only a
single pass through the machine.
