Ernst, those are indeed the old numbers. When Epson made the 9000 to 
9500 conversion option, they suggested that each tech doing these carry 
2 spare light ink heads in case of problems. Now Epson only supplies 
the single part number (F055070) and I know it is used for the 
5000/7000/7500/9000/9500 printers, as well as some Mutoh and maybe some 
Mimaki. It is supposed to be of higher quality than the F055050 head.

I've got to replace the flex lines in my 9500, as well as swab out the 
stainless lines, and replace a couple of heads that I cooked. When the 
heads get hot, I lose a couple of nozzles, that comes from running them 
at 100% too often with a bad supply of ink. The peizo gets hot, and 
things in the head change. Then whenever they get too hot, they stop 
pumping like they should. Then the printer will get converted to a 
grayscale system in conjuction with the new version 4 Evolution RIP.
