Digital BW, The Print

First, thank you for responding to my query re. printing problems with 
my R1800.  I think I am getting close to resolving issues and awaiting 
new inks to find out.  I now have some questions regarding a previous 
post where you are identifying inks you use as you are experimenting 
with the new gloss papers.

Another reader responded:  "So lineup, from left to right is as 
follows? ---

Normal: Y M C MK PK R B GO
You: Pk cln Eb Eb Eb cln GO GO"

Here is my question:  As the cartridges EB for the PK, MK, and GO are 
not interchangeable, how do you achieve printing capabilities with MIS 
PK in the Y position, Eb in the C position and GO in the B position.  
When I posed that question to Inksupply.com, they had no idea.  I 
assume you must be using a continuous feed system.  Are those carts 
still available?

Thank you in advance.  Nancy
