Digital BW, The Print

hi all.

i'm printing BO with MIS's GP (Ultrachrome equivalent) inks on a 1280.

starting yesterday I'm having a problem I can't seem to fix.  I get irregular cyan and magenta bands in my images, it extends beyond the actual print area.  looks like something is leaking or dirty.

i tried printing a bunch of pages with cyan and magenta and tried a couple of cleaning cycles.  no go.

does anyone know what i can do or clean to fix this?  timing is according to murphy's law because i have a bunch of photos sold and paid for and can't print :(

if it helps:  i use cartridges;  the black one i refill myself and the color one is stock MIS.

thanks so much as always.

cheers,

boris
