(Gamma adjustment)
After completion of the above procedures, perform the following
procedures.
1) Enter the gamma level with 10-key.
2) Press the [P] or [START] key.
When [START] key is pressed, printing is performed and the
adjustment value is set simultaneously.
Check the gamma density (copy density in the low density
area and the high density area) of printed copy image.
The greater the adjustment value is, the greater the gamma
value is, resulting in a higher contrast.
(Copy condition setting in this simulation)
To select paper (paper feed tray), perform the following procedures.
1) Enter 0 with 10-key.
2) Press [START] key. (The mode is changed to the paper feed
tray selection mode.)
3) Enter the number corresponding to the paper feed tray to be
used with 10-key.
4) Press [START] key. (The paper feed tray is selected.)
