Digital BW, The Print

I am new to this group so first let me just say "hi".

I have two printers, a 1270 that I use for colour work and a 1200 
that I am dedicating to black and white printing. A few months after 
I bought the 1200 it was stolen, along with a ton of other computer 
stuff. Several months went by before the gear was recovered. Several 
more months went by before it was returned to me.

The printer had been used but when I got it back the black cartridge 
was missing. It has taken awhile finding drivers and such but finally 
it is up and working...sort of.

The black head seems to be really plugged up. I used a cleaning 
cartridge in it prior to installing MIS variable inks in it but after 
several cleaning sessions two sections of the test pattern are still 
incomplete.

Any suggestions or does this need to go into the shop for a 
professional cleaning job?

Also, the choices of paper that are available on the 1270 are not 
listed on the 1200. Not sure if this is a driver problem or not.

thanks in advance for any help.
