Does anyone have a scan of the MX-80 Dot Matrix
Printer Technical Manual?
It's apparently intended to be available here:
http://www.computinghistory.org.uk/det/39747/Epson-MX-80-Dot-Matrix-Printer…
but I was unable to actually download it.
If you do get the site working, or contact the site owners, this one might also be worth
getting (?7.5 rather than ?0, but also fails to check out):
http://www.computinghistory.org.uk/det/32320/Epson-FX-RX-MX-Printers-Produc…
Covers FX-85/185, FX-80/100, RX-80/100, MX-80/100.
(Principles of Operation, Wiring data, Repair Analysis Procedures, Parts Lists, Repairs
and Adjustments, Final Actions, General)
This book on pages 11-12 has a brief overview of the differences between the MX-80
versions (suggesting mostly firmware differences, and with the Type III including the
previously optional Graftrax 80 support):

This VCFED thread also discusses the ROMs (and the 5152 printer):

The Graftrax 80 installation manual also has a component layout diagram on page 4:

Here is the Epson MX-80 III FT - Sams ComputerFacts:

Here is the IBM 5152-002 - Sams ComputerFacts:

If you do manage to get hold of either of those Epson PDFs on computinghistory.org.uk,
I'd be very keen as well.
