2. Copier-specific Adjustments 
 
(5) Enter adjustment mode [05]. Change the values for codes [590] to [592] to adjust the gamma balance in each 
of the low- and medium-density area.

* Set the value in increments of approximately 20, while checking the copy image until the optimum value 
is obtained. (Note that gradations (density level) in the medium- and high-density areas may be reversed 
with some setting values.) 
 
* Since the subcode varies according to the area where the density is adjusted, refer to the table below and 
set the appropriate subcode.  Remember that mainly adjusting the low- or medium-density area will change 
the copy density of the images seen through the back of the page.   Setting "2" for the subcode will allow 
you to adjust the high-density area.  But this will not solve the problem.  Therefore, never change the value 
for the high-density area.

 Caution after the adjustment 
The adjustment may possibly cause text handwritten with a pencil or light text to become illegible on the copy.  
Therefore, carefully perform the adjustment, while checking the copy image.

 Remarks 
Enter a value within the recommended value range mentioned in the procedures.  Otherwise, it may cause a loss 
in MFP performance, including degradation in the image quality and a reduction in the life of the consumables.
