1PCLBSET DADF 2 faces color differ crrct ref side
Lv.1 Details To set which side of the front or back side should be the reference
side when correcting a color difference at the time of duplex stream
reading.
The correction result is reflected after executing the following
operation: specify the reference side, execute a series of color
difference correction processing, and then turn OFF/ON the power.
Use case Before starting correction of color difference in DADF duplex printing
Adj/set/operate method Enter the setting value, and then press OK key.
Display/adj/set range 0 to 2
0: N/A, 1: Front side, 2: Back side
Default value 0
1PCLBUDR DADF 2 faces clr differ crrct lowr limit
Lv.1 Details Colors which do not need to be corrected are sometimes corrected
as a result of correction of color difference in duplex stream reading.
To keep colors which do not need to be corrected, the correction
amount is adjusted so that the effect of correction is weakened.
The result is reflected when correction of color difference is executed
again after the setting is made.
When "1: ON" is specified, unnecessary correction is not executed,
but an expected effect may not be obtained for other colors.
Use case If the color difference occurs on the colors which didn't have any
difference before correction, adjust the correction amount before
executing the color difference correction again.
Adj/set/operate method Enter the setting value, and then press OK key.
Caution Expected correction result may not be obtained.
Display/adj/set range 0 to 1

0: OFF, 1: ON
Default value 0
1PCLBOVR DADF 2 faces clr differ crrct upr limit
Lv.1 Details Excessive correction is sometimes made when correcting color
difference in duplex stream reading.
To control excessive correction, adjust the correction amount to
weaken the effect of correction.
The result is reflected when correction of color difference is executed
again after the setting is made.
When "1: Weak control" or "2: Strong control" is specified, excessive
correction is not made, but an expected effect may not be obtained
for other colors.
Use case If the color difference occurs on the colors which didn't have any
difference before correction, adjust the correction amount before
executing the color difference correction again.
Adj/set/operate method Enter the setting value, and then press OK key.
Caution Expected correction result may not be obtained.

CLM-PLTN Sampling of color copyboard read MTF VL
Lv.1 Details The MTF value for the Reader Unit is sometimes displaced from the
factory setting value depending on the condition at transportation/
storage. If the machine is installed without correcting the value, it
may cause an image failure such as moire. Therefore, it is necessary
to readjust the MTF value by reading the MTF adjustment chart at
installation.
When color copyboard reading is performed, the controller performs
sampling of the MTF value. This value is set in COPIER> ADJUST>
CCD> MTF2-Mx, MTF2-Sx.
Use case At installation
Adj/set/operate method 1) Set the MTF chart on the copyboard glass.
2) Select the item, and then press OK key.
Display/adj/set range During operation: ACTIVE, When operation finished normally: OK!

CLM-DF1 Sampling of clr front stream read MTF VL
Lv.1 Details The MTF value for the Reader Unit is sometimes displaced from the
factory setting value depending on the condition at transportation/
storage. If the machine is installed without correcting the value, it
may cause an image failure such as moire. Therefore, it is necessary
to readjust the MTF value by reading the MTF adjustment chart at
installation.
When color front side stream reading is performed, the controller
performs sampling of the MTF value. This value is set in COPIER>
ADJUST> CCD> MTF2-Mx, MTF2-Sx.
Use case At installation
Adj/set/operate method 1) Set the MTF chart on the ADF.
2) Select the item, and then press OK key.
3) Perform color front side stream reading with the MTF chart set on
the ADF. (CLM-DF1)
