Epson DFX 9000

3.1 Overview

The printer may exhibit different symptoms for the same problem,
which makes troubleshooting more difficult. This section, however,
provides simple and effective ways to facilitate troubleshooting.
In addition, the User's Manual for the EPSON DFX-9000 describes
detailed steps to be taken for recovery from typical user errors.
Before you disassemble the printer, disconnect the
W A R N I N G
power cable and data interface cable.
Allow sufficient time for the motors to cool before
touching them. Some of them get hot enough to burn
you.
Use only specified tools to avoid impairing the quality
C A U T I O N
of the printer.
When troubleshooting motors, always check the driver
circuit as well, and vice-versa. A malfunction in one of
these components can cause the other to fail - and will
cause the replacement part to fail as well. Always
check both the motor and driver.
Use only specified lubricants and adhesives.
Carry out any necessary adjustments by following the
specified procedure.
Wear a grounded wrist strap to discharge static
electricity from your body.
