Digital BW, The Print

I have two 1400's both bought at the same time. One will load and print perfectly Bockingford Inkjet paper, weight 190g.

The other will not load whatever I try, I have cleaned the feed roller, tried a gentle push, also put a piece of low tack film at the point that the feed roller hits the paper, also tried the envelope setting, all to no avail. 

Only one point that I can think of is that the machine that feeds OK has always had Epson Claria carts in it, the other machine has a home made pigment setup, based loosely on Paul Roark's.
