Hello all, I am new to Signs 101 and we are having issues with our Mutoh 1638X. We have 2 new heads with maybe 30 hours on them and head 2 seems to be firing cyan randomly , when we do nozzle check's the last black & cyan nozzles are missing. I never had a head strike, and believe the head is not damaged? Do you think maybe 1 of the carriage cables might be damaged and not communicating properly to head 2. thank you
