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 contains 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. - 20 -
