Operation
(*1) Destination Check is for the operation on the different product (destination) with the previously operated product
(destination). It is the reset relying on the recognition regarding the destination change by PJL command and the
operation at POWER ON of the new product EEPROM as an error.
(*2) It is reset to 0 limited by Page Count less than 500 pieces. (ENGINE RESET due to PJL Command is not in this
limitation.)
(*3) About DOT SHIFT setting menu, even it is also exist in System Maintenance Menu, but because the setting
value keeping area is allocated in PU EEPROM AREA, in the case of the item of System Maintenance Menu
initialized, DOT SHIFT setting is not initialized. By contraries, in the case of PU EEPROM AREA initialized, DOT
SHIFT setting is initialized.
(*4) DOT SHIFT setting should not be initialized.
(*5) Because of the support of Toner TAG, Toner Dot Counter is not reset.
