AR-M550/M620/M700  SETTING AND ADJUSTMENTS  7 - 30

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. 

• One or more consumables (OPC drum, developer, transfer belt)

have been replaced. 

If the copied test chart (UKOG-0162FCZZ) image includes a back-
ground copy of patch 3 rather than patch 2, adjust all-copy mode to the
image density level specified above.

(Copied image gamma, copied image sharpness)

Normally, default settings should be applied to 'copied image gamma'
and 'copied image sharpness', but images should be adjusted accord-
ing 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 .

2) Go through the modes specified in Simulation 46-2.
