Paper won't feed on this printer. usually, after the first page prints, i have no more problem. it's getting the first one to print is the problem. Envelopes are tricky also.

I had this same problem - you could hear the printer "trying" to pick the paper up.  After a few cycles it would stop  and pop up the media jam error.  I noticed this would never happen when the try was half to completely full - only when the stack was low.  I pulled put the paper, inserted a feather duster, applied some elbow grease (or wrist in this case) - problem solved.

any stripes are usually caused by imagining unit, first use the tool in front cover to clean laser glasses. inspect IU drums for stripes maybe youll need to change them. is the page coming out ok, but picture is printed crookedly ?

did you put these envelopes right way (portrait/landscape) also you have to change in printer menu paper source paper type from plain paper to envelope.

pleas check the driver settings, maybe there is a setting fit to paper or something.

In your print driver, you need to go to the Printer Features -> Media 1 window and specify "Thick 2" and then go back to the main print window and specify Paper Feed "Tray 2" Then go to the copier,, place the stock into tray 2 and match the paper setup for that tray on the copier to "Thick 2" for tray 2.

Basically, both the Mac and the copier need to match paper types and feed tray.
