How?I try crossover cables and problems from C/B goes to M/Y channel.So problems is definitely somewhere in C/B sections.I print last time before 10 days.Turn on,do some test print-OK.When try print job C/B uncontrolled print.

in sp 540 the yellow and magenta is in same head
you can revese the cables cards between magenta and yellow if the problem move to yellow here you have a problem in cable card you can check it if you repace it with another
but if the problem stay in magenta here you must replace the head

i crossover both cables from CB to MY and problems move from CB to MY.So that is indicators both printheads and printhead cables are good.Problem is somewhere behind.

You will have to replace those print-heads. Those are old print-heads. Despite that thing, they are working on SP, SC and SJ series.
Good luck with that!
