Digital BW, The Print

My C86/EZW refillables combination has recently developed a paper 
feed problem: when printing anything that occupies roughly the bottom 
1"-1.5" of an 8.5x11 paper, the print heads seem to "hang up" on the 
right-hand (as viewed when looking at the printer during printing) 
corner of the paper.  This results in 3 things: a funny noise, a 
turned up corner soaked in ink, and misaligned printing on the image 
itself, evidenced by a kind of "ghosting".

This didn't happen before I got the refillables (with the super size 
black), though I'm certainly not ready to blame it on the new carts.  
The paper thickness doesn't seem to matter, because this problem is 
showing up on 188gsm photorag.

Any ideas?
