Digital BW, The Print

Haven't got the banding back yet, so all is well, and clogging issues 
are few.

Now what I get, only on Photorag 308 gsm letter size are thin score 
lines running parallel to paper travel. This only happens in areas 
that have more than about 90-95%k ink layed down with IP5, and it 
doesn't do it on Eclipse. And it's intermitant wrt area of print- only 
two or three wheels are doing it on letter sized paper, it doesn't go 
across the whole page. But it is exactly repeatable in same spots when 
print is redone. To get even further pirsnickity, you have to look 
obliquely at the print to see it but it is definitely there like 
scratches. Naked eye visible.

Prints from last week on this paper don't show it. The only thing 
that's different is I opened a new box, I did a realignment on 
printer, this time using the 17 mil photorag instead of "plain paper" 
as Epson suggests in their manual. In all cases I leave the lever all 
the way up (normal, not thick paper or envelope setting). Humidity is 
controlled to be the same as last week(45%RH), but temperature today 
got to about 79 degrees F. Last week it was 68-72.

Any ideas? After all this happened I gently reached my hand in and 
realized that the entire Pizza wheel frame is spring loaded against 
the bottom transport. Perhaps a judicuous use of a bit of light 
springy foam? Return printer? TIA,
