Lexmark International Inc 5056 Manual De Usuario

Try a sample of any envelopes in consideration for use with the printer before buying large quantities. 
See 

 for instructions on loading envelopes.

When printing on envelopes:

To achieve the best possible print quality, use only high-quality envelopes that are designed 
for use in laser printers.

Set the Paper Source in the Paper Menu based on the source in use, set the Paper Type to 
Envelope, and select the correct envelope size from the operator panel, the printer driver, or 
from MarkVision Professional.

For best performance, use envelopes made from 90 g/m

2

 (24 lb bond) paper. Use up to 105 

g/m

2

 (28 lb bond) weight for the 250-sheet standard tray or 105 g/m

2

 (28 lb bond) weight for 

envelopes as long as the cotton content is 25% or less. Envelopes with 100% cotton content 
must not exceed 90 g/m

2 

(24 lb bond) weight.

Use only new, undamaged envelopes.

For best performance and to minimize jams, do not use envelopes that:
–

Have excessive curl or twist

Are stuck together or damaged in any way

Contain windows, holes, perforations, cutouts, or embossing

Use metal clasps, string ties, or metal folding bars

Have an interlocking design

Have postage stamps attached

Have any exposed adhesive when the flap is in the sealed or closed position

Have nicked edges or bent corners

Have rough, cockle, or laid finishes

Use envelopes that can withstand temperatures of 230°C (446°F) without sealing, excessive 
curling, wrinkling, or releasing hazardous emissions. If any doubts exist about the envelopes 
considered for use, check with the envelope supplier.

Adjust the width guide to fit the width of the envelopes.

Load only one size of envelope at a time in the tray. Envelopes may only be loaded in the 
standard tray. Load them with the flap down and the flap to the left of the tray.

A combination of high humidity (over 60%) and the high printing temperatures may seal the 
envelopes.
