Stefan,
In looking at the service manual for the R380, I see a number of
features that should make it an excellent pcb printer. The main one
is that the head height is controlled by a motor! The feedback for
this motor is via a photointerruptor and a disk with 4 tabs
representing the 4 presets that are selected by the paper type
operator input. The lowest paper PG (Printhead Gap) is 1.2 mm, while
the cd/dvd PG is 4.2 mm, so I'm hoping to be able to print 3 mm
pcbs! Spoofing the sensor should be simple, hopefully to the point
where it can be continuously adjusted to match the board thickness.
Now, I hope the paper path will be as cooperative!
