Envelope--flap is sealing when envelope is printed

I have a color laser printer #3600n. When I print an envelope the flap is sealed when it comes out. How do I fix this?

Re: Envelope--flap is sealing when envelope is printed

While there is undoubtedly an "envelope specification" in the printer documentation, I have had the best luck with peel-and-seal envelopes with vertical seams. The fuser softens the glue on conventional envelopes (thus sealing them) and (at least in my printer) diagonal seamed envelopes tend to jam.

Are you using envelopes specifically for laserjets? If you aren't you are just going to damage the fusing assembly.

Try using the envelopes with the peel-off adhesive instead of the lick-able type.  

 

As far as damage to the printer goes, as long as the adhesive stays inside the envelope (the flap doesn't expose the adhesive while it goes through the rollers) the worst case is a jam.

Re: Envelope--flap is sealing when envelope is printed

If you happen to live in an area with high humidity levels. the envelopes may be absorbing the mositure from the air, which could lead to the envelopes sealing during the fusing process.

 

I have two suggestions

 

1.  Store envelopes in a sealed container with some silica gel to absorb moisture.

2.  I have heard of people microwaving their envelopes to "cook off" the moisture.  I don't know if that really works or not.

 

I think the sealed container & silica gel is probably the best way to go.
