Adjustment
005
ADF Buckle Adjustment 1
Adjusts the roller timing at the skew correction sensor/entrance roller. A larger
setting causes more buckling.
[–12.0 to +12/1 mm]
-12 = -3.0 mm
+12 = +3.0 mm
006
ADF Buckle Adjustment 2
Adjusts the roller timing at the interval sensor/scanning roller. A larger setting
causes more buckling.
[–8.0 to +8/1 mm]
-8 = -2 mm
+8 = +2 mm
007
ADF Trailing Edge Erase Margin (Front)
These settings adjust the erase margin for the trailing edges for the front.
[–20 to +20/1 mm]
-20 = -10 mm
+20 = +10 mm
008
ADF Trailing Edge Erase Margin (Back)
These settings adjust the erase margin for the trailing edges for the back.
[–20 to +20/1 mm]
-20 = -10 mm
+20 = +10 mm
 Normally, the interval sensor detects the leading edge of small originals (B6, A5, HLT), or
originals for duplex copying, and delays the start of the scanning roller for the prescribed
number of pulses to buckle the paper and correct skew. This feature can be switched on
for all paper sizes with SP6020 (ADF Contact Mode In/Out). However, switching this
feature on for all sizes reduces scanning speed slightly.
