Digital BW, The Print

OK...finally am taking the plunge and getting the 1280 refillable 
carts, and am a little confused trying to get around the MIS/Inksupply 
website.

First, I have the carts in my basket, But I cant find glop anywhere, 
and I know it is on there somewhere. Also, Where is the chip resetter? 
And lastly, I am assuming that I need bottles of ink for all of the 
slots except yellow, which will get the glop. Correct? I have a few 
eboni carts, and since I mainly do glossy prints, They will last a long 
time. Should I experiment with PKN? I am planning on keeping the eboni 
since I do make big matte prints sometimes. Thabnks inb advance for 
clueing me in! Doug M
