One very annoying problem is that Fuji is no longer cutting either regular CA paper or Supergloss in 30X40 sheets. You have to purchase it in 32 inch wide rolls, which means you either have to make two cuts
on the material or design a slightly longer drum. Another design problem is that the Jobo-style lids simply
fills and drain too slowly for precise color work: a lot of chemistry has to get through a small hole. The CPI-style lid is far superior in this respect, with the chemical entering and leaving around the entire rim.
