6-5 
Scanning speed - platen   
[-5.0 to 5.0 % / 0.5 / 0.1%] 
Adjust the scanning speed of the scanner. 
6-6  Scanning speed - ADF mode   
[-5.0 to 5.0 % / 0.0 / 0.1%] 
 
Adjust the scanning speed of the ADF. 
Scanning speed (platen/ADF) 
1.  Make copies of the test pattern printed during the previous adjustments 
( previous page), in platen mode at 90 rpm (speed 3). Use the 10th print for 
the adjustment. 
2.  The length of the 8 squares in the feed direction should be 130 mm. 
3.  If it is not, calculate the reproduction ratio using the following formula.{(130 - 
Value) / 130} x 100 = ± X.X % (Round off to one decimal place) Example: If 
the value is 133, {(130 - 133) / 130} x 100 = - 2.3 % 
4.  Access SP6-05, input the calculated ratio, and press the Enter key. 
5.  Check again to make sure that the ratio is correct. 
6.  Make copies of the test pattern in ADF mode and repeat the process using 
SP6-06. 
6-7 
Skew Correction - ADF   
[-5.0 to 5.0 mm / 0.0 / 0.1mm] 
Adjust the skew correction of the ADF. 
6-8 
Scale shadow mask -platen   
[2.0 to 10.0 mm / 2.0 / 0.1mm] 
Adjust the scale shadow mask of the scanner.
