Digital BW, The Print

I'm going to suggest two possibilities that I really don't have a lot 
of confidence in...so consider it a shot in the dark to check for, and 
maybe someone else will have a better idea.

1) Dirt under the head deflects the stair pattern in a nozzle check, 
also is responsible for blobbing. Corrected by paper towel under the 
head trick.

2) You don't state if you use a CIS/CFS or carts, but if the cart 
clamp has been removed for these, or if the carts aren't simply seated 
well for some reason, I had heard somewhere third-hand that this 
causes overspray. I don't know, maybe if you have ink caked up at the 
bottom of nipple you would get the same effect of cart rising, though 
I think the chip connector would start getting upset at this point and 
give you a red light.

Not likely, but easy to check....
