We just recently bought and installed a used 3404DI press. After a few weeks of getting everything set up to print, we excitedly printed for the 1st time. Unfortunately, come to find out, the cyan and yellow are off from the magenta and black by 3 mm consistently. We have proven that the cylinder of the 1st tower is literally off time from the others by attempting to align the timing holes. Just wondering if anyone has any idea how to fix this or what could be causing this, because right now even our Ryobi tech is a bit stumped.
