3.3. Action at Power On
When you apply power to the converter, the following procedure will
be executed:
1. The permanent memory will be read to determine whether it con-
tains valid data. If so, the data will be loaded into the temporary
memory and normal operation will be started on the basis of the
permanent settings.
2. If the data in the permanent memory area is unreadable, it will be
cleared. The factory defaults are then read, and an error message
will be printed containing a description of the action taken. See
the chapter on Error Messages in the FSL and PCL
programmer’s guides. Operation starts on the basis of the factory
default settings.
3. The converter checks the printer. If the printer is malfunction ing,
the converter’s indicators will signal an error.
