AR-M550/M620/M700 SETTING AND ADJUSTMENTS 7 - 36
If the print density is not at an acceptable level, do the following steps.
6) Adjust the print density by entering an appropriate value through
the numeric keypad.
A larger value provides higher density.
7) Press the P or Start key
This applies the adjustment value.
Pressing the Start key starts print operation as well as applying the
adjustment value.
8) Check the printed image density.
Repeat steps 6 to 8 until an acceptable image density is obtained.
This adjustment is needed in the following situations:
• The CCD unit has been replaced.
• U2 trouble has occurred.
• The MFP control PWB has been replaced.
• The EEPROM on the MFP control PWB has been replaced.
• The scanner control PWB has been replaced.
• The EEPROM on the scanner control PWB has been replaced.
• One or more parts of the scanner (reading) section have been
replaced.

The image density settings should be normally left at defaults but
should be adjusted according to user requests, if any.
1) Set the test chart (UKOG-0162FCZZ) on the original table so that it
aligns with the front frame. Then put four or five pieces of A3 (11" x
17") paper.
