Enter the self-diagnosis (Level 1) mode, and continue to press the 11111 and 55555 keys until “NV-RAMINITIAL” appears on the upper display (the 11111 key is for test item increment and the 55555 key fortest item decrement).2. The table No. to be initialized appears. There are two tables to be initialized.Hold the 22222 and 66666 keys down until a target table No. shows up (the 22222 key is for table No.increment and the 66666 key for table No. decrement).3. The upper “NV-RAM INITIAL” starts blinking upon pressing the 33333 key, and all the items in Table4-3 are initialized by holding the key down for 10 seconds.4. Press the 44444 key to end the test (the display of step 1 is restored).Table 4-3 (1/2) Initialization Items in Table 1NV-RAM INITIALTABLE 1Table 4-3 (2/2) Initialization Items in Table 2Initialization ItemDrum CounterBelt Unit CounterFuser Unit CounterToner CounterBlackYellowMagentaCyanBlackYellowMagentaCyanDetailInitializes the internal counter after the replacement ofeach drum.Initializes the internal counter after the replacement ofthe belt unit.Initializes the internal counter after the replacement ofthe fuser unit.Initializes the internal counter after the recovery fromeach toner low error.Initial Value0000Unit————RegistrationSet.Pointx-axisRegistrationSet.Pointy-axis(Left)RegistrationSet.Pointy-axis(Right)Engine ParameterYellow LEDMagenta LEDCyan LEDYellow LEDMagenta LEDCyan LEDYellow LEDMagenta LEDCyan LEDDetailInitializes the X-axis correction value for theLED head (Yellow/Magenta/Cyan).Initializes the Y-axis left-correction value forthe LED head (Yellow/Magenta/Cyan).Initializes the Y-axis right-correction value forthe LED head (Yellow/Magenta/Cyan).Initializes all the items that have been setusing levels 2 and 3.Initial Value000Unit1/1200 inch1/1200 inch1/1200 inchInitialization Item
