3) Enter the adjustment value with 10-key.
In case of increase of image density, input large numeric
value. Or in case of diluting the image density, input small
numeric value.
4) Press [OK] key.
5) Press [Close] key to exit the simulation.
6) Make a copy in the single color copy mode and check the
copy.
If a satisfactory result is not obtained, return to the SIM 46-25 mode
and change the adjustment value.
Repeat the above procedures until a satisfactory result is obtained.

20-R DSPF mode copy density adjustment
(Normally not necessary to adjust)
It is normally not necessary to perform this adjustment.
In the following cases, however, this adjustment must be per-
formed.
* When the copy density differs in the DSPF mode and in the doc-
ument table mode.
* When the copy density differs on the front surface and on the
back surface in the DSPF mode.
* When the copy density in the DSPF mode is too low or too high.
* When the DSPF unit is replaced.
* When the DSPF unit is disassembled.
* When the DSPF CCD unit is replaced.
* When U2 trouble occurs.
