On alot of printers when you print envelopes theres a back door on the printer to prevent the curling or wrinkles. Just open the back door when doing envelopes.

Best of luck and have a happy and safe 4th of July weekend!

Envelopes thru bypass only....once they are set youl need to set the bypass to envelopes at the machine either thru user tools or by pressing bypass then the # key and selecting envelope or custom size and entering the size of your envelopes.
Back at the computer go into print proprties and select paper souce bypass the printdriver will use the machine settings unless ou tell it otherwise

Select envelope, after you hit print. Run one first on a sheet of regular paper, to see the orientation. Then, just put them in, the way you have it set up for.

Most laser printers have an "S" paper path. They cannot help bending paper. I would suggest you print lables instead of envelopes if you send several letters. If you only send 1, hand address the envelope. Not elegant ut it works.

Envelopes can be printed from tray 1 or 2. Select the type of envelope you are using from the PRINT dialog box or the driver. In your program, set the margins. Typical margins for a commercial #10 or DL envelope would be: Return Address Top margin 15mm(0.6 Inch) Left margin 15mm(0.6 Inch), Delivery Address Top margin 51mm(2 Inches) Left margin 89mm(3.5 Inches). For the best print quality, position margins no closer than 15mm (0.6 Inch) from the edges of the envelope. Avoid printing on the seams of the envelope. Envelopes with a peel-off adhesive strip or more than one flap that folds over to seal must use adhesives that are compatible with the heat and pressure of the printer fuser. the extra flaps and seals can cause wrinkling, creasing and feed jams, could even damage the fuser.

you have to tell the printer in the print que that you are using envelopes and what size envelope.
-Carl, please let me know if this helps.

What error if any do you get? Sounds like your printer needs a firmware update.
