IT is a long list so I will try.
First off it was laying so much ink it was not drying fast enough to even use the take up real,
Crop mark sensor would not read the crop marks. (there is an aftermarket filter to put over the sensor)
Take up real stopped working had to get a new motor.
went daily coming into work with Red Lights flashing. Never found out why as it would shut down for its own protection. Firmware fixed but we had to shut main power of at night.
still can not print at night because we need to tap an ink pouch at least once every 2-3 hours as it thinks it is out of ink.
If you do not print White at least once a week it takes about 2 hours of cleanings and test prints to get it back
There is a little piece of metal that protects the print head that just snaps on. Mine broke the clip and started to hit the media clamp. Roland said i had to get a new head(non warranty) My supplier took on off a dead head and snapped right on.
Now I am having problems with Print cut using crop marks. Starts off great but slowly the cut gets off worse and worse the further away from the original origin point.
There where a few other small thinks that I can not remember but that is the just of it.
Like I said before, My suppler (Pacific Coast
Sign Supply) has been great, Out normally same day or next and he has helped out a lot. And Firmware has fixed a lot as well
