42641101TH Rev.1 48 /Oki Data CONFIDENTIAL3.1.3 EEPROM Initial Setting Range for EventsAs for initialization of EEPROM, ranges differ the whole phenomenon."O" is initialized. "–" is not initialized.Table 3-1 The Initial-Setting domain of EEPROMCU EEPROM Area PU EEPROM AreaNo Events(*1) The model (forcing) which operated before is for operating as another model (forcing), and a Brands check isrecognized as an error and resets change of the Brands point by the PJL command, operation at the time ofthe power supply injection by new EEPROM, etc.(*2) It restricts to the time when whose page counter is 500 or less sheets, and is reset by 0. (ENGINE RESET bythe PJL command is not this limitation.)(*3) Although a DOT SHIFT setting menu exists in a system maintenance menu, since setting value preservationarea is arranged at PU EEPROM AREA, even when the system maintenance menu item is initialized, a DOTSHIFT setup is not initialized. On the contrary, when PU EEPROM AREA is initialized, a DOT SHIFT setup isalso initialized.123456——OO——User MaintenanceMenu EEPROMRESET OperationF/W Revisioncheck error at thetime of a poweron.CU EEPROM areamapping Revisioncheck error at thetime of a poweron.Brands area checkerror at the time ofa power on.(*1)EngineMaintenanceMenu ENGINERESET OperationPU EEPROM areamapping checkerror at the time ofa power on.FactoryDefaultAreaOOOO——UserMenuArea—O—O——F/WRevisionArea————OODrumCounter————O(*2)OPageCounter————OOToner DotCounter—OOO——Administrator Menu/ SystemMaintenance MenuArea(*3)—————O(*3)Engine Maintenance Menu Area———O——BrandsArea
