Operation/Procedure
(Copy mode selection)
1) Select the number corresponding to the copy mode to be adjusted
with 10-key. (Select one of 3 - 14.)
2) Press [START] key.
(Print mode selection in the FAX mode)
1) Enter 2 with 10-key.
2) Press [START] key.
3) Select the number corresponding to one of the following adjust-
ment items. (Select one of 3 - 14.)

4) Press [START] key.
(Gamma adjustment)
After completion of the above procedures, perform the following proce-
dures.
1) Enter the gamma level with 10-key.
2) Enter [P] key or [CUSTOM SETTINGS] 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.)
NOTE: When [P] key is pressed after entering an adjustment value in
this simulation, the adjustment value is set. When START key
is pressed, the adjustment value is set and copying is per-
formed.
Press [START] key. Press [CUSTOM SETTINGS] key.
