1.4.27 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 
for correcting developing bias voltage is adjusted.

<Operating procedure>

(1) Press the 

7

 and 

2

 keys in this order in the initial state of the maintenance mode.

"PLS WAIT 72" is displayed on the LCD. 

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

the maintenance mode.  If the sensitivity adjustment of the density sensor fails, "ERROR 
72" is displayed on the LCD.  Display the error message by pressing the

key, and take 

the following measure that corresponds to the error message.

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