1PSCLB-B Exe frt/bck clr differ calibration: bck
Detail To read the PG for calibrating color difference between the front and back sides with the Scanner
Unit (for back side) in order to correct the color difference between the front and back sides at
duplex stream reading.
A significant color difference may occur between the images on the front and back sides scanned
with the DADF caused by variations in the LED and changes in durability. Such a color difference
is corrected by executing 1PSCLB-B following 1PSCLB-A.
Use Case When a significant color difference occurs between the front and back side at DADF duplex reading
Adj/Set/Operate Method 1) Place the paper used by 1PSCLB-A on the DADF so that the front side is faced down and the
cyan image is placed at the left rear side.
2) Select the item, and then press OK key.
Caution - Do not turn OFF/ON the main power switch during execution of 1PSCLB-A and then 1PSCLB-
B.
- Until 1 is displayed in both 1P-ERR-A and 1P-ERR-B, calibration of color difference between the
front and back sides is not completed.

1PCLBUDR ON/OFF frt/bck clr dif calibr l-lmt set
Detail To set whether to set the lower limit of the target color difference for correction when correcting
color difference between the front and back sides at duplex stream reading.
In some cases, colors which do not need to be corrected are also corrected by performing color
difference correction at duplex stream reading.
When 1 is set, the correction level is adjusted to weaken the effect of correction. Unnecessary
correction is not executed, but an expected effect may not be obtained for other colors.
The result is reflected when color difference correction is executed again after the setting is made.
Use Case
When color difference occurs on the colors which did not have any difference before correction
Adj/Set/Operate Method
Enter the setting value, and then press Apply key.
Caution
Expected correction result may not be obtained.

Detail To set whether to set the upper limit of the target color difference for correction when correcting
color difference between the front and back sides at duplex stream reading.
Excessive correction is sometimes made when correcting color difference at duplex stream
reading.
When 1 or 2 is set, the correction level is adjusted to weaken the effect of correction. Excessive
correction is not executed, but an expected effect may not be obtained for other colors.
The result is reflected when color difference correction is executed again after the setting is made.
Use Case When color difference occurs on the colors which did not have any difference before correction
Adj/Set/Operate Method Enter the setting value, and then press Apply key.
