Messages
The EPSON Stylus Pro 9000 performs self-diagnostic tests using the data
supplied by its various sensors, and if an error is detected by one or more
sensors, a corresponding error message appears on the control panel display.
No matter what kind of error occurs, use the Error Message List for Service
Technicians table on page 58 or the General Error Message List table on page
58 to determine what and where the problem is, as well as where to look for
directions on fixing the problem.

Table 3-3 lists the printer errors that users can check and troubleshoot by
