Check your capping station, damper, do a head clean, nozzle wash. All the usual stuff. If the channel doesn't recover nozzles, consider replacing the head. Same as usual when you have nozzles missing.

Nozzles are restored after one normal cleaning, but when I’m starting to print in 4 pass cyan is missing, I’m cleaning - test nozzles is good, if I starting to print 8 or 10 pass - cyan in its place. I think it damper problem, but why 10 pass print is normal

Sounds like ink starvation, so yeah, first bet is dampers. Might be worth flushing the line as well.
