Dell 5110cn Color Laser Printer - Manual (Page 116)

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 at
the rear, 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:
Set the Paper Type to Label in the Tray Settings. Set the Paper Type on the printer driver.
Do not load labels together with paper or transparencies in the same tray. This may result in a jam.
Do not use label sheets with a slick backing material.
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 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.
Portrait orientation is preferred, especially when printing bar codes.
Do not use labels that have exposed adhesive.
