I'm still using an Epson Stylus 400 (10+ years old) with cheap refill dye ink
because the genuine cartridges are discontinued.
After upgrading the PC (debian linux), i couldn't get all the unexposed resist
to develop off the pcb.
After testing the UV blocking of the ink with a UV light meter, i found the
black ink is only blocking two-thirds of the light.
The printer used to put out bucket loads of ink on to the gelatine transparency
such that it would pool for a second before soaking in.
Because i've got a detailed user manual, developer manual, and source code to
the printer driver (gutenprint), i'll figure out how to get more ink out.
