I'm about to covert an Epson 4900 to the Piezography digital negative inkset. I have experience making digital negatives with the 3880 but not the 4900. I have a number of questions starting with, what is the best feed method for the film into the 4900. I would love to correspond with anyone who has or is using the 4900 for digital negatives. Any hints or advice for a 4900 novice would be greatly appreciated.
