4.1 OVERVIEW
Since the adjustments required for EPSON Stylus Photo 700 and Stylus Photo EX is the same
with the one for EPSON Stylus Photo, refer to the service manual (Chapter 4 Adjustment) of
EPSON Stylus Photo for actual procedures.
4.1.1 Printhead ID Input
Since EPSON Stylus Photo 700 and Stylus Photo EX supports high resolution Super-micro dot
printing, a unique ID number should be defined for EPSON Stylus Photo 700 and Stylus Photo EX.
When you perform the printhead ID input operation with the adjustment program, confirm the
printhead ID number indicated on each printhead unit and input them with the program.
 For EPSON Stylus Photo 700 and Stylus Photo EX
Printhead ID: 6-digit number (Example: S2OLIX)
 For EPSON Stylus Photo
Printhead ID: 5-digit number (Example: 03204)

TROUBLESHOOTINGS
Since the basic design and the structure of the printer mechanism and the electrical
circuits are the same with EPSON Stylus Photo, refer to the service manual for EPSON
