There are two ways to achieve running envelopes.
***But before we go into that, let me say that running envelopes on a machine that is not intended to specifically run them...will put a lot of wear and tear on the machine. If you have a service contract that gives you free parts,supplies and service...then you wont be that bad off. If you dont have a contract, I would really suggest against it!
(1) the first way , I find to be the easiest. You will need to unfold the flap on all your envelopes. Make sure when you are unfolding the flap, that you get them very flat. You may need to even fold the flap backwards once to counter act the fold. You will then be able to load them in horizontally, with the bottom of the long edge loaded in.
This way they will not crease. But you will wind up with a few crooked envelopes , usually off by about 2-4 mm. If you load in a stack of 24-35 I would guess you would get about 3 crooked ones.
(2) the 2nd way , you will get all straight envelopes. But it is much harder to do. You will need a 2nd fuser that is only for envelopes. Depending on the machine konica,xerox canon....it will be a little different on all of them. But, basically you will need to a just the rollers on the fuser so that there is more room for the envelope to pass through. There are usually springs and two top screws holding that top roller down. You need less pressure. Once you are able to locate the actual area that is providing the pressure, you will need to back it off. Each machine is different. It may be between .0250 of a millimeter to a full millimeter. A justing your fuser is hard and I can tell you, I trashed two fusers just figuring it out.
A dedicated envelope machine is best in the long run. If you have the money. Xante provided the easiest to use and good quality. But the machine is costly to run as far as supplies. I am not sure about the lifetime either. Some options proven options are PSI and OKIDATA.
If you have any questions feel free to shoot me an email. Any time that we are not busy with our own customers...I am happy to help other PrintPlanet members.

, that's #1, as for #2 - it is pressure in the fuser that does a creasing, older b/w HP laserjets had a lever that user would've flipped up to run envelopes which decreased the fuser rollers squeeze, You can do the same but this will turn your machine in to Envelope printer and may (most likely will) affect printing on flat media but if you absolutely must - have a tech decrease fuser pressure to the point where toner is fused and creasing is less noticeable... I am not familiar with design of your machine but if, say, fuser is easy to change yo can get 1 fuser optimized for envelopes and other for regular printing, swap'em when you need to.
