Dell 3000cn Color Laser Printer - Manual (Page 60)

Use envelopes that can withstand temperatures of 205°C (401°F) without sealing, excessive curling, wrinkling, or
releasing hazardous emissions. If you have any doubts about the envelopes you are considering, check with the
envelope supplier.
Adjust the width guide to fit the width of the envelopes.
To load envelopes in the multipurpose feeder, insert the envelopes either with the flaps open and toward the front of
the printer, or with the flaps closed and the short-edge of the envelopes facing into the printer.
See " Loading the Multipurpose Feeder " for instructions on loading an envelope.
Use one envelope size during a print job.
Make sure the humidity is low because high humidity (more than 60%) and the high printing temperatures may seal
the envelopes.
Labels
Your printer can print on many labels designed for use with laser printers. Label adhesives, face sheet (printable stock), and
topcoats must be able to withstand temperatures of 205°C (401°F) and pressure of 25 pounds per square inch (psi).
Before buying large quantities of any print media, Dell recommends trying a sample first.
When printing on labels:
Do not load labels together with paper or transparencies at the same time. This may result in a jam.
Do not use label sheets with a slick backing material.
Do not print within 1 mm (0.04 in.) of the die cut.
Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam. Partial sheets also
contaminate your printer and your cartridge with adhesive, and could void your printer and cartridge warranties.
Use labels that can withstand temperatures of 205°C (401°F) without sealing, excessive curling, wrinkling, or releasing
hazardous emissions.
Do not print within 1 mm (0.04 in.) of the edge of the label, of the perforations, or between die-cuts of the label.
Do not use label sheets that have adhesive to the edge of the sheet. Dell recommends zone coating of the adhesive at
least 1 mm (0.04 in.) away from edges. Adhesive material contaminates your printer and could void your warranty.
If zone coating of the adhesive is not possible, a 3 mm (0.125 in.) strip should be removed on the leading edge, and a
non-oozing adhesive should be used.
Remove a 3 mm (0.125 in.) strip from the leading edge to prevent labels from peeling inside the printer.
Portrait orientation is preferred, especially when printing bar codes.
Do not use labels that have exposed adhesive.
Storing Print Media
For proper print media storage, the following guidelines help avoid media feeding problems and uneven print quality.
For best results, store print media in an environment where the temperature is approximately 21°C (70°F) and the
relative humidity is 40%.
Store cartons of print media on a pallet or shelf, rather than directly on the floor.
