(2) Density adjustment procedure
a. Collective adjustment of two or more copy quality modes
Normally this adjustment is performed with SIM 46-2 and SIM 46-3. In
this method, two or more copy density adjustments in different modes
can be adjusted collectively.
1) Execute SIM 46-2 and SIM 46-3.

If the copy density is too light, increase the adjustment value.
If the copy density is too dark, decrease the adjustment value.

b. Individual adjustment of each copy quality mode
This adjustment is used when a different density level for different
copy quality mode is required. SIM 46-5 to -7 and SIM 46-9 to -11 are
used.
1) Execute the simulation corresponding to the copy quality mode to
be adjusted.
2) Press the COPY button to make a copy.
Check that the copy density is as shown in the table below. If not,
change the adjustment value.
For the auto mode, there is only one adjustment value. For the
other modes, the adjustment value for each density level must be
adjusted.
E. Paper feed
(1) Manual paper feed size detection level adjustment
1) Execute SIM 40-2.
2) Extend the manual paper feed guide fully.
3) Press [MAX POSITION] on the LCD of the operation panel to
highlight it.
4) Press [EXECUTE] on the LCD of the operation panel to highlight
it.
If normal, the highlight is shifted from [MAX POSITION] to [MIN
POSITION].
5) Narrow the manual paper feed tray guide fully.
6) Press [EXECUTE] on the LCD of the operation panel to highlight
it.
Check that [COMPLETE] is highlighted.
7) Press the CA key to cancel the simulation.
