I think 80% of all printing issues with these machines can be traced back to the maintenance station, or just the capping unit and wiper. I have been using an old VJ1604 for about 4 years now and it still has a head unit in it that was 4 years old when I bought the machine. Apart from a few other minor issues and replacing a couple of dampers, every problem I have ever had with printing issues has come back to the maintenance station or blocked drain lines.
My Mutoh is capable of printing flawless prints if looked after.
So here is my two bobs worth for an older Mutoh.
1. Run cleaning fluid through the capping station twice a week and manually remove blockages because most banding issues (on my machine) have been caused by clogged drain lines.
2. Clean the wiper and its surrounds along with capping unit once a week.
3. Keep a spare maintenance station on hand.
4. Replace the wiper at least 4 times a year.
5. Keep the whole area around the head clean as this will prolong the wiper life.
All done.
