1.4.18 Sensitivity adjustment of density sensor (Function code 72)

<Function>

This function allows you to print the patch data for density sensor sensitivity adjustment on the 
belt unit and measure the density with the density sensor.  The characteristics of the density 
sensor are calculated based on the value measured by the density sensor, and the parameter 
is adjusted upon color density adjustment.

<Operating procedure>

(1) Press the

or

button to display “MAINTENANCE 72” on the LCD in the initial state of 

the maintenance mode.  Then, press the 

OK

 button.  “PLEASE WAIT” is displayed on the 

LCD.

(2) When the parameter is obtained without errors, the printer returns to the initial state of the 

maintenance mode.

When an error message is displayed on the LCD, take the measures described in the 
table below.

* # indicates the toner color (Y, M, or C) of which cartridge became empty.

Note: 

If you replace the main PCB ASSY, be sure to carry out this procedure.  This function 
must not be executed until it is verified that the printer is in the ready state.
