that is a bad sign. you are having data issues. either from a loose data cable. but more possibly a blown head. i'd give you some pointers about a data swap that would diagnose if it is your slider board or head. but, i don't think i want blood on my hands if you do the swap wrong and fry your printer.
at least recheck your cables and make sure all the ends are clean with no fraying or bent ends, and that they are plugged in firmly. turn off your machine on front, switch off on back, unplug, and press the front power button four times before doing any poking around in the head carriage. and try to keep one hand on the platen if possible.

That is a loose head data cable most likely.
Turn off your printer.
unplug your printer
Cycle the power switch to insure there's no power left in the system.
remove the damper to the affected head ( make sure you pull straight up and don't break the nipples on the manifold to the head)
Gently remove the plastic cover over the magenta head ( the dampers for the heads to the side will be partially over the top of that plastic cover wiggle it free)
Gently push down on the ribbon cables on the head, making sure they are seated fully
replace all the parts in the opposite order
power up and see what you get.

first just inspect the cables and or swap the cyan with one that is working to see if the issue stays at the head or follows the cable. if it stays at the head, it can be a bad slider board port or ink inside the head's ribbon cable input.
attached is a rendering of a data swap that will be needed to isolate if the
data is good coming from your mainboard and slider board.

test prints like that make baby jesus cry.
best of luck. search function on these forums will turn out TONS of threads with similar issues which wind up ending with head replacement and more threads about how to replace heads and then more threads about aligning those new printheads. Worth your time digging through for valuable info, otherwise its worth paying the $$$ to get a tech in there to flip your machine back into a workhorse in no time.
