AR-M550/M620  SETTING AND ADJUSTMENTS  7 - 37

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.

1) Go through the modes specified in Simulation 46-21.

2) Select the adjustment item SCANNER EXP. LEVEL using the

numeric keypad. 

3) Press the Start key

4) Enter the image density adjustment value. 

5) Press the P or Start key

Note: Adjusting the scanned image density through this simulation

changes the image density settings for all scan modes to the
image density level applied by carrying out this simulation. 

The scan-mode image density settings for individual scan modes
adjusted through Simulations 46-22, -23, -24, -25, and -45 are
changed to the image density level applied by this simulation. 

Scanned images must be visually checked to ensure the post-adjust-
ment image density.

This adjustment is intended to the image mode for each scan mode
individually. In manual mode, the image density setting for each
scanned image density adjustment level (1 to 5) can be adjusted to a
custom density level. 

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 simulation modes that correspond to the scan

modes for which to adjust the scanned image density (i.e., the
modes specified in Simulations 46-21, -22, -23, -24, or -25).

3) Enter the number that corresponds to the following adjustment

item using the numeric keypad.  (Choose from numbers 0 to 5.)

• Auto mode

• Manual mode (print density adjustment level)

For manual mode, select the number that corresponds to the
image density adjustment level (1 to 5).  (Choose from numbers 1
to 5.)

6) Press the Start key

7) Enter the image density adjustment value. 

8) Press the P or Start key

Scanned images must be visually checked to ensure the post-adjust-
ment image density.

1) Go through the modes specified in Simulation 46-27.

2) Using the numeric keypad, select the number that corresponds to

the scan mode for which to make adjustments. 

4) Press the Start key

5) Adjust the gamma by entering an appropriate value through the

numeric keypad. 

A larger value provides larger gamma gradient and higher image
contrast.

6) Press the Start key

This applies the adjustment value. 

Scanned images must be visually checked to ensure the post-adjust-
ment image gamma.

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 CIS unit has been removed. 

• The CIS unit has been replaced. 

• The SPF unit has been removed. 

• The SPF unit has been replaced.

1) Using the numeric keypad, select the number that corresponds to

the mode for which to make adjustments.  (Choose from numbers
2 to 4.)

2) Press the Start key

3) Using the numeric keypad, select the number that corresponds to

the operation mode. 

4) Press the Start key. 

AE fix OFF: Density (exposure) is automatically controlled on a real
time basis. (The density level is dynamically changed according to the
original's pattern.)

AE fix ON: The density of the leading edge of the original is detected
and used to determine the overall density (exposure) level. (The over-
all density level is fixed.)

This adjustment is needed in the following situations: 

• Paper is jammed in or around the fusing section.

• Printed images are unclear or deflected in areas close to the paper's

leading and/or trailing edges.

Adjust the fusing paper guide position by loosening the fusing paper
guide fixing screws and the sliding the fusing paper guide in the arrow
direction.

Note that the fusing paper guide is fixed to the center by factory
default.

This adjustment is needed in the following situations: 

• The manual paper feed tray section has been disassembled. 

• The manual paper feed tray unit has been replaced. 

• U2 trouble has occurred. 

• The PCU PWB has been replaced. 

• The EEPROM on the PCU PWB has been replaced.
