2.3 Automatic adjustment of auto exposure
(50%, 100%, 154% and 200%)
Note: Before performing automatic exposure
adjustment, check to make sure that
manual exposure adjustment for 100%
has been properly done.
(1) Make sure that “AJ” is shown on the dis-
play.
(2) Place blank A3-sized (or Ledger-sized)
copy paper on the glass and set it against
the original scale, then close the original
cover.
(3) After keying in code “49”, press the PRINT
key and the automatic adjustment
of auto exposure commences. (The car-
riage, lens unit and mirror unit, respectively,
move to the positions corresponding to the
four reproduction ratios, making the expo-
sure lamp also to light four times.)
Note: Do not touch the machine while it is
performing automatic exposure ad-
justment.
(4) When the display changes to “AJ”, the au-
tomatic adjustment is complete.
(5) Make copies at the respective reproduction
ratios and check the image density. (In the
“AJ” mode, simply press the ENERGY
SAVER
key to make copies.)
(6) If the image density of test copies is not
appropriate for any reproduction ratio, make
adjustments in Sec. 2.4 Automatic exposure
adjustment (d), (e), (f) or (g) for the inap-
propriate reproduction ratio.
