Digital BW, The Print

I bought some of the heavy PR paper and was printing last night in my 2200.  
The first few prints went fine and then once again (second time using 308) the 
printer refused to draw the paper down to print.  Anyone had this with the 
heavy PR?   I only have this problem with the heavy thick PR.

The printer reports an error, no paper or a jam.  If I look down inside while the 
printer trys to find paper I can see the rollers or what grabs the paper isn't 
even close, like it is pushed back aaaway from the paper.  Finally I load some 
thin just letter paper and it will grab that and print.  Then I go to EEM and it will 
work.   

I had the printer set to accept the thin paper, letter or EEM.   Later after dinner I 
went back to 308 PR but I had the printer set to the envelope setting and I got 
4 prints through fine.

So how do those that use the 308 PR in a 2200 have theirs set?  

I'm thinking that whatever has tension to grab the paper gets pushed back by 
pulling thick paper through the printer when the printer is looking for thin 
paper, and that when I reinstall thin paper it "finds its way?" again.

 I don't overload the printer with paper, maybe 6 sheets at a time.  When in "I 
can't load paper mode" the printer won't even grab a single sheet if that is all 
that is loaded.

Is the envelope setting the trick?  BTW I noticed in the 2200 manual that OS X 
and single sheet back loading aren't compatable. I never tried rear loading 
one sheet at a time so I don't know.   Maybe there is a patch at the Epson site 
now that OS X and teh 2200 have been out for a while.

Thanks
