Digital BW, The Print

Hi all. 

I am using a 1400 with CIS UT14 from MIS. Mac OS 10.6 with QTR and photoshop

I started getting some faint banding and a row of very small lines just outside the border of my images. These very short lines (half mm) run along the long edges of my prints they occur about 12/cm for the length of the prints. 

I did what I think is a thorough reallignment with the epson utility - at the end the first two rows had #5 perfect and the third row had three very faint bands on #5.

Any thoughts?

Thank you, 
Dean
