Igor,

Weird !! in the first place.

My best guess is something with the paper sensor located on 
the head carriage and/or the auto check for paper thickness. 
The printer reports a smaller sheet to the driver than 
inserted. Other test would be similar paper as thick or 
thicker + feeding the Photorag at 90% if it is grain 
related. Either a loose electric connection of the paper 
sensor or deflection of the paper sensor light path because 
the sensor itself isn't fixed rigid enough or at a small 
angle instead of loodrecht :-).  Then there is the less 
likely chance the coding strip or whatever method they use 
on the 3800 isn't reading the position of the head carriage 
correctly: filth on the strip, or coding sensor dislocated 
to the strip when thicker paper is going through the 
printer. The 9000 model had similar problems with the coding 
strip.

Epson's problem now I think.
