*2: When the image registration automatic adjustment operation is 

abnormal, it is judged as an error or not.

• After replacement of a toner cartridge

• At every 8000 copies (total of print and copy)

(When, however, 8000 copies is reached during a job, the operation 
is stopped after completion of the job.)

If the adjustment is not completed normally, "ERROR" is displayed.
In case of an error, the contents of the adjustment are not revised.

Operation

1. Press the [EXECUTE] key.
The amplifier gain adjustment of the black image density 
sensor is automatically performed. 
After completion of the adjustment, the result is 
displayed and the [EXECUTE] key display returns to the 
original state.
