    Hello everywon

    brand new to this forum, Aussie field service engineer

    this canon machine has had a new print head fitted, ink supply checks OK, however one yellow block is not printing at all (attachment supplied)

    i am looking at replacing the Head Relay PCB, then the Carriage Relay PCB, then the Flexible Cable, then the Controller PCB in that order

    i was wondering if anyone has had the same problem and can help with a firm diagnosis

    any assistance very much appreciated

    Andy
