AR-M550/M620  SETTING AND ADJUSTMENTS  7 - 31
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.
3) Using the numeric keypad, select the number that corresponds to
the copy mode for which to make adjustments.  (Choose from
numbers 3 to 6.)
4) Press the Start key
5) Press the Start key (A copy is created.)
Check the density of the copied image. 
If the copied image density is not at an acceptable level, do the fol-
lowing steps.
6) Adjust the copy 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 copy operation as well as applying the
adjustment value. 
8) Check the copied image density. 
Repeat steps 6 to 8 until an acceptable copied image density is
obtained. 
Note: Adjusting the copied image density through this simulation
changes the copied image density settings for all copy modes to
the copied image density level applied by carrying out this simu-
lation.  Also, the copied image density gradient is automatically
adjusted to the specified level.
The copied image density settings for individual copy modes
adjusted through Simulations 46-9, -10, and -11 are changed to
the copied image density level applied by this simulation. 
This adjustment is intended to customize the copied image density set-
tings. The copy density setting for each copy density adjustment level
(1 to 5) in manual copy mode can be adjusted to a custom density
level.
1) Set the test chart (UKOG-0162FCZZ) on the original table.
2) Go through the simulation modes that correspond to the copy
modes for which to adjust the copy density (i.e., the modes speci-
fied in Simulations 46-9, -10, or -11).

(Fax mode density)
The print 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 . 
2) Go through the modes specified in Simulation 46-12.
3) Select the adjustment item (FAX EXP. LEVEL) using the numeric
keypad. 
4) Press the Start key. 
5) Press the Start key (A copy is created.)
Check the print density. 
If the print density is not at an acceptable level, do the following
steps.
6) Enter the print adjustment value using the numeric keypad.
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.
