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.
